Mercedes Benz R-Class W251 tips, tricks, spark plugs, belt, tensioner, misc maintenance repair 

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.

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.

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.

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

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.

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....

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.

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

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!

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.

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.

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

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.

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.

Wow! Fantastic tutorial. Great job. Thank you

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!

Thanks for the tips Big Bro definitely from tech to tech✊🏽especially the Safety. Saftey First

Thank you enjoy your video. God bless you and yours

Purchased a 2007 with 149k miles paid 6k. Everything looks great on the car and I'm excited about driving it around

Great video! I really enjoyed watching.. cheers from another youtube wrencher👍

I fix by myself! Perfect! Thank you!

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...

Looking at purchasing a R350 soon , I am amazed at how easy it is to replace the spark plugs compared to M113 engine. Is crank sensor at rear of engine and how easy or hard to get too

Man I have been looking for this kind of help!

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.

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?

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?

Save!🙏🙏🙏

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?

👌

Thanks my friend

I have a 2010 R350 that will not switch to 2nd gear. any suggestions? by the way enjoyed this video. learned a lot. 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 ?

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.

Great video ! Subscribed! My R350 runs like shit

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.

Nice video, which spark plugs do you recommend to MBr350 thanks 🙏🏼
