Thank you
I've owned my '07 R350 for 14 years now and this guy's tips and tricks are great. Learned many new things in his video. I recommend it to all R350 owners that do their own work.
Lou, I am fortunate to have recently found your channel. I have a C350 (w203) & my wife drives an R350 (w251). I've been working from home now for over a year and fixing the cars myself has been a way to save a bunch of money. You've given me the confidence to do things I never figured I'd know how to do. (I've been a Wall Street guy...soft hands, LOL) I'm grateful for all of your useful tips and detailed explanations you provide. I think it's totally interesting and beneficial that you include mentioning the quirks and nuances of these German cars. The way the locks on electrical harnesses and drains work are examples. I especially like the importance you give to staying organized. My teenage sons are watching your videos too, and I'm glad that you set a good example, demonstrating the proper way to approach a complex job like this.
Thank you so much for reaching out! This is my goal of the channel. To educate. My aim is to help. So I truly appreciate those that can appreciate my information. Thanks again for taking the time to watch and comment! Be safe. Lou
I own a 2013 R350 BlueTec, just changed oil today. I really appreciate the small tips (we called best practices in IT) you gave for almost everything. This is really helpful for DIY guys like me who never got any formal training.
thank you!, more to come.
terrific vid for us amateur wrenches who want to keep our cars away from the dealers. Been driving high end MBs for over 40 years and always do most stuff myself. Yes you need the right tools, and you need guys like this who can walk you thru the steps. I would opine that this guy has more attention to detail than most of the mechanics at the dealership. MBs depreciate like a stone. The are way over engineered with unnecessary technology gizmos that do break. The running gear is actually not that bad. The engines are ok. I change my oil approx every 5K and use a vacuum pump so i don't need to get underneath the car. My r350 is pushing 200k and runs like a sewing machine. My 320e wagon is at 188k. Same. Had 2 S classes, lost the first one in a divorce deal and exwife couldn't handle the maintenance, but she was able to run it into the ground, and i'm happy it kept her safe. I would say don't buy a used MB unless you can wrench on it yourself. Thanks for this great video.
35:19 That is why they offer a lifetime warranty. 👌 I still have Hazet sockets in a toolbox I got for my birthday in 1984. Same sockets, same toolbox. 😁 Thx for the video.
Hi, Now I understood why my MB W251 y.2012 is so often in MB workshop for repairing different items. I just took not sufficient service on it. After watching your video I plan to take more care now ;)) I go to my garage with tools now....
Glad to assist, be safe, hope my videos help. Lou
Great video, very informative. Full of real world explanations. Not that I could do much of what’s explained my self, but it’s good knowing how everything hangs together. Thanks!
Thanks I appreciate that!
You are appreciated sir. Buddy hooked me up with an 06 R500 . In love first Benz ever!
Great video. Just got an R350 a couple months ago I want to renew the car. Thank you for your content
Great video tutorial Lou. I learned a few things that will help me with my rclass, as well as a few things that will help me with life itself, lol. Your the man, keep 'em coming.
ha thanks Jeff, mission accomplished man! Be safe, Lou
So glad I found your channel. I have a 2006 R350 4matic. I love how you are explaining things in details. And no it is not boring to hear your advice. Finally someone who is working on R350s. The hardest thing to do on this vehicle was the fuel tank sensor. No one has done a video on that. But my buddy mechanic and I figure it out.
Thank you, I appreciate your nice comments. I hope this video helped you.
Wow this is an awesome video. I own a w163 with a m113 that just got written off im looking at buying a w251 with m113. I was a little worried about engine accessibility but after seeing your video im commited. Thanks for your video’s
Wow! Fantastic tutorial. Great job. Thank you
Thank you!
I fix by myself! Perfect! Thank you!
You are welcome! Thank you! Lou
Thanks for an informative video. I love my rclass and believe it or not my biggest frustration is the over engineered rear door. The shocks that hold it up are “hidden” in the roof of the car and makes the headliner have to come out to replace. But can’t complain because everything else has been great :) new subscriber
Steve Wilson thanks! Much appreciated!
I appreciate your level of concern, it's refreshing. I followed the same rules back when I was in customer service. I'm not rich, The car is not a status, I had a 123 and 124 years ago, solid cars, wanted hopefully my last car, to another. a 14 W212 M276. with 138k. I'm slowly getting maintenance up to date, with a few repairs, cold start rattle. I used scan tool to observe cam position, left bank erratic both intake and exhaust, so I'll be replacing secondary cam chain tensioners. 7/13 I assume it has the check valves. But, it has no money lights on, drives flawlessly, but. Scan data shows codes for missing messages with RFK at Head unit and Ignition Switch Module, STORED. If I clear these they come right back on restart. I guessed a connection on CAN network. Another person stated RFK, ISM, SCM, TCM, and DME with loose pins, or broken solder joints in all these modules, that only the RFK is sensitive enough to set codes, but those others are about to fail they're just not bad enough to set a code. Kinda goes against my experience and logic, but I'm not ruling out till enough evidence refutes claims. I assumed a loose connection or green crusties on a CAN line connector or Bus. Thoughts? Not looking for a "Silver Bullet" just your experience with similar concerns.
Regarding your codes, if there is no customer complaint, meaning you dont observe any functionality issues, then codes dont matter to me. I wouldn’t chase them. Thats our rule of thumb . No customer complaints? Dont worry about codes.
@@MasterTechLou Thank you Lou, you are correct. I was saying out loud the answer to my problem all along, "the car presents no concerns". Thank you for a very informative video, I will continue to get the maintenance sorted on this ol' gal. You have helped remind me of some things i'd forgot, as well as other things to take note of. Please, keep up the good work, my friend.
@@r.weaver3769 Thank you I truly appreciate that!
Great video! I really enjoyed watching.. cheers from another youtube wrencher👍
My plastic pulley broke on the highway on my way to GA on Christmas Eve. It left me stranded. Good video and I wish knew these pulleys issue before. I guess they last around 100k miles and fail.
Oh man sorry to hear!
My ML350 has the same engine and I get p0016. My engine is not part of the recall.
just subscribed! detailed information! hope you can do more videos on mercs!
thank you, if there is something you would like to see just let me know . I will try.
Thank you enjoy your video. God bless you and yours
Angie S thank you! Same to you, be safe. Lou
Awesome video!
Thank you for this video
Thanks for the tips Big Bro definitely from tech to tech✊🏽especially the Safety. Saftey First
Thanks my friend
good video . well done. i just subscribed
thank you!
Man I have been looking for this kind of help!
I need help with my 06 R350 W251 losing acceleration intermittently
Thank you Keith, is there something specific that was helpful to you? thanks for viewing, hopefully you subscribe , Lou
I've been watching you for a while, THANKYOU, I got a mystery for you. I have a 2007 R350. I love this car. I have over 250k on it and still love it! My battery went bad. I replaced the battery. After wards a couple of things happened. The wipers stopped working, thanks you solved that problem with this video! I tried to open my rear hatch. It unlocked fine but would not lift! I manually opened it and pushed all the proper buttons and it would not close. I closed it and it locked fine. I prefer to do work myself but I realize there are somethings I cannot do. Can I repair this myself? Thank you so much. I live in Oklahoma so good Mercedes mechanics are no easy to find. I really appreciate your help, tips and your integrity! Unfortunately, it is a rare commodity these days! BTW, Happy New Years!
Richard thank you so much! Happy new years as well. Most likely the hydraulic pump or module failed. Its tricky to tell the difference.
Benz-Tech Lou Thanks Lou. Is there a way I can test this? What is the difference between the pump and the module? BTW, I love your SERVICE philosophy! I've always tried to do the same! I spent a lot of my own hard earned money on this car and I ,I've it when people respect that. BTW, I am retired and on a fixed income. I would love to work but I have macular degeneration and have lost a lot of my eyesight, especially my detail sight. I just replaced the air ride struts on my front end, so I can do things. It just takes me longer and I have to pay extra attention. I love doing things myself when I can. I finally found the left gate pump! It's on the left side. Thanks again!
@@rdpurdom if you can jump the pump it will tell you if it works or not, usually the wiring corrodes at the pump, or there is water and corrosion in the module.
Benz-Tech Lou , just wondering, is there a fuse or something I need to check? It happened at the exact time that my battery died. Thank you
awesome! love your ideology
Great great great video!!!!! ❤❤❤❤
Wow thanks!
great ethics bro !
I appreciate that man!
Purchased a 2007 with 149k miles paid 6k. Everything looks great on the car and I'm excited about driving it around
Congratulations, we (techs) loved out shuttle R class, we took it everywhere:) lunch, long road trips for morning coffee, bachelor parties. Shhhh :)
@@MasterTechLou yes I'm very happy with it. My brother told me to check the air bags and they look great also the brake pads look like the are new. It's always such a gamble with used cars but this one looks like the previous owner really cared about it.
You bought yours for 6k? Waow why market was that
The engine is so small compares to mine. So much space to work with, envy.
This is a great video you just same me an hour drive and a lot off money
What a wonderful video! I have learned a lot from it. Could you do a video to replace the tailgate latch? Thanks!
My 2010 R350 tailgate will close but fail to lock close. One can hear the clicking sound of the tailgate tried to lock but failed. Is it the latch motor? Thanks again.
Thanks! Yes its a latch that has failed In your car. Im sure there are plenty of videos showing how to replace the latch it really is a simple process. I don’t have the car in my possession or else I would my friend. Thanks!
@@MasterTechLou Thanks for your time to reply. Unfortunately, I cannot find any video on the latch replacement for Mercedes! A video will help many people in the same situation as mine. Thanks in advance.
I have R 350 CDI, it's an amazing car
2 pairs of eye's? NICE!
Save!🙏🙏🙏
Crazy
I would love to bring my car to you...I have a 2010 R350, rear hatch issues, pinch protection issues?, rear SAM issues, and now cylinder 4, 5, 6 misfires...(just 2 days ago). Did not want to take it to the dealer, took it to 3 indy's who could not diagnose (or did not take any time) for poop...I'm 5 hrs north of you though...
Oh man sorry to hear. Rear hatch issues are easy to diagnose and the misfires are most likely a bad cat clogging the exhaust.
Hi, great vid, I loved it. Gives me motivation to give more care to my R500 5.5l. Any chance for inputs on how to conduct a maintenance on doors and especially roof top?
Yes certainly! I will do one soon thanks for the idea! Hopefully you subscribe:)
@@MasterTechLou absolutely, can't wait 😉👍
Awesome video I have R class 500 And I'm getting a esp malfunction and run flat inflation malfunction on my dash. Only 89,688 miles Any idea?
Yes tons of ideas however I will not "diagnose" via the comments, it can cause issues with others with the same problem. If you would like my help you can reach me at my website. www.cartechconnect.com I can help you. thanks, Lou
Thank a lot. And I'll look forward to chatting
I had a bad coil on Cylinder six, so I went ahead and replaced all six since they all were the originals. I also replaced all six spark plugs since I was there, and replaced the air filters as well. I could not have done this without your video for sure! My idler pulley's are kind of noisy, any advice on which brand and part number(s) I should buy to replace them with?
Glad I could be of assistance! Ive used the ones at O’Reilly’s with no issue in the past. I prefer dealer parts but those can be pretty pricey and its just a pulley so, not hard to replace if theres an issue.
@@MasterTechLou Thanks a million Lou!!!
Lou, I have a 2011 R350 Bluetec and recently found water in my rear fuse box. Do you have any videos that show how to repair a seal or gasket leak on the rear glass roof ? I would really like to see if possible as there telling me they have to remove the headliner in order to do the repair? Any advise or thoughts
water leak tests can be a pain, check the tubing from the hatch to the body it can crack and leak. its usually not the glass. also check the taillight seals. those are the two common.
I have a 2010 R350 that will not switch to 2nd gear. any suggestions? by the way enjoyed this video. learned a lot. thanks.
You have a obvious transmission problem. You will need a good scanner to read the transmission control module for the code. You most likely have to have the dealer replace the control unit/conductor plate.
First let me say this video was very informative! I really appreciate your work! That being said...I am looking to purchase a 2011 R350 4matic with 80k miles. What if anything should I be concerned about? The vehicle runs very well as far as I can tell, but I don't want any surprises. Any information would be appreciated! Thanks.
They are honestly solid cars. Great year to own. Biggest concerns are checking near the battery and rear trunk area for water stains. These cars were horrible with water entry. That Kiils the fun in owning these. Id recommend doing a pre purchase inspection at a Mercedes dealer and asking them to go through the car and make sure the battery area is clean and clear. The rest is easy maintenance. I loved these and sad to see them discontinued. Best of luck.
@@MasterTechLou...Thank you so much for your input. I have since purchased the vehicle and love it! This machine is amazing and solid! Thanks again!
Nice video, which spark plugs do you recommend to MBr350 thanks 🙏🏼
Double platinum or iridium tipped bosch from the dealer but the parts store ones will work the same. I just prefer dealer plugs :)
@@MasterTechLou thanks
Can you confirm is that tool brand you showed a A model line that Benz Techs use or is that just what you went with ?
There is no one brand. Techs use whatever they like. Hazet and stahlwille (probably spelled wrong) are German toolmakers that mercedes special tools come from. So I willingly and rarely will get those brands. But other then that there is no secrets to our success 😊. Whatever tools you like.
I need help! My dad has Mercedes R320i and when he presses gas sometimes car doesn't respond automaticlly.. I would like to hear you opinion on this. Thanks!
Hello, our cars have a lag in time between pressing the gas and when the cat actually responds. You would need a scanner to verify live data of the accelerator pedal. But anytime theres an accelerator pedal issue or inlet port issue there should be fault codes as well.
I received my 2006 R350 from Japan on 31st Dec 2020. I had to jumpstart it in order to drive it home. The following day I checked main battery voltage which recorded 3.25 volts. I replaced the main battery, and the car started well (no more jumpstarting). However, the dashboard now gives white battery display. Could this be an Auxiliary Battery problem? How do I fix it? Please help.
Yes sir, always replace the small aux battery when you replaced the main one. The small one always dies once the main one dies. Hope this helps! Lou
Hey lou, I replaced my backup camera on my r class because it wouldn’t activate and the problem has not been remedied. What would it be? Software update?
Hey sorry not sure why I did not see this until now. if you still need help you can find me on my website. Thanks,Lou
Hi Lou, I have a 2006 R500 that is flashing “Drive to workshop without changing gear”. It is in park and does not shift out of it. Using the iCarSoft CR Pro scanner, there are no current codes but the TCM has code 0513 in the historic state. What needs to be done to fix this? Any advice is greatly appreciated.
You either have a failed transmission control unit or ism.
@@MasterTechLou thank you for the reply. If I decide to replace the control unit, will any coding need to be done? Can the CR pro do it?
@@victorvaldez3802 only the dealer scanner can program the transmission control module. And very very few others so im told.
@@MasterTechLou sounds like this isn’t a DIY project.. I’ll have to drag it on a flatbed and get it to a repair shop. Thank you very much for the insight!
Just had the same issue with my r500, had to replace the ISM.
Nice detailed video. I am considering buying R class, what can you say about its reliability
Łukasz Drobnik do not buy the diesel. Also do not buy 2006-2008 and you will be happy. These are great cars. Very few issues outside of water leaks to the interior.
@@MasterTechLou Thanks, great video. I have 2008 and have no problems. It is still running like new.BTW, I do all maintenance myself.
@@MasterTechLou Agree, I only replaced two NOX sensors in the last 7 years. This costed me 3K at the dealer. I won't buy the diesel if I knew. But this year I learned a lot myself and hope to deal with everything myself from now on. I just brought a iCarsoft MB v2.0 too.
@@MasterTechLou where do the water leaks come from
@@glendonhines9022 sunroof drains. Taillight seals, rear tailgate door tubing to the roof. Windshields. Loose evaporator drains. Those are the common places.
What to do if The key does not lock the steering wheel?
How many miles should valve seals last on the 2007 R500 5.0l V8? Mine is burning oil.. 153k...
Hello and thanks for watching! Well you are at about the right mileage. it all depends on how the oil looks through the oil fill cap. if you see any signs of sludge then its for sure valve stem seals. if you do not then it can still be valve stem seals especially if you get a poof of smoke on startup when cold. also you might have some cylinder scoring.
Bro!! I bought my R350 new in 2010.. and been checking for videos for years! Hardly anything out there. I want to do more maintenance.. what do you recommend that I can purchase. A book with pictures or a CD.. help me out. The damn dealership doesn’t help for shit! They take my money and that’s it! Thanks for the video!
Ebay, buy a set of WIS discs or a download (I prefer discs). Its the workshop information we use in the dealer and it also comes with epc which is our parts catalog. That will help with working on these. Appreciate you reaching out!
@@MasterTechLou Roger that! thank you brother. I appreciate the feedback. I know you’re busy.. so it means a lot for you to take two minutes of your time! Thanks again!
My rear brake lights and indicators don't work. Any suggestions?

How we can check the fluid level on the transmission on r350
Checking the fluid is not an easy process if you do not have a scanner, trans filler or rack. Its a somewhat tedious process. There are ways to accomplish this but there is no dipstick. In short you need to overfill trans and then let it drip out to a very fine drip at a specific temperature based on your trans pan and options.
Great job. Where are you located
Thank you, Central Illinois. I made a video on my experience. Thanks!

Thank you for your service. I appreciate You reaching out. Please dont make the mistake most do and obtain a Mercedes on a fixed income. I know its not my place to say so, but ive had a lot of bad stories that all start out this way my friend.
Hello I agree about the Fixed Income but… I had a Nice almost $100,000 Nest Egg and it was Stolen by my Drug Addicted Home Health Care Aide. My Grandmother got me the car. She was trying to be Special, I guess due to the Cancer and it will be my last car. It’s Beautiful. It just needs some TLC and a few Flaws fixed.
Thanks for the videos!👍👍 You are the sexiest bald guy ever !! With all due respect! And I'm not into guy's 😄 But you sound like a solid person! I tell you this if you help me fix my car and I save 500.00 dollars. I will send you 200.00 dollars out of appreciation and gratefulness. I will do that,because the fact that you save me so much money . Blessings on this new year 2021.
Ha thanks! Bald is beautiful! I appreciate the thought. I do. Whats the problem with the car? I don’t normally like to diagnose cars in the comments as ive stated in the video. But if I can help, I surely will. Lou
@@MasterTechLou Listen friend, I got friends of mines that shaved their heads to have the bald look,but is not for everyone. You nailed friend. The car situation is difficult. My sister owns a mb r350 4matic 2011,in a strike of brightness she placed a 5 gallons of paint in the back of the vehicle. Needles to say it spilled and she went to the car wash and hose it off. The SMS is in the back and so is the fuse box. We purchased the parts but our Mechanic is unable to flash it. Everything works with the exception of the fuel gauge. I'm just wondering why everything is working if he never flashed? To top it,she already paid 500.00 to the guy. Same guy I took my c230 kompressor because a braking problem and never was fixed. I don't know what to think. Thanks for your response and no disrespect intended. Blessings to you and your family in this new year 2021.
