Huge issue with those vibrations... W220 S500 RWD only. Before couple of years i replace the center support bearing, because it was shaking terrible when i hit the pedal. After that everything was fine. Year later, i notice that there is new vibrations coming from under the car at speed from 80kph to 130,and they are not constant?!?! Something like a resonance, 2 seconds vibrating and 2 seconds not... wth. I've changed almost everything,both flex discs, new support bearing again, motor mounts, everything worned on the suspension, wheel balance 4 times, just everything suspicious ,and the f*cking vibrations still remain...... There is no strange noices from the wheel bearings, nothing! Next thing will be both axles with their CV joints and i hope that the case will be closed... Pls help,if you have something in your mind about. 🙏

I have a 2005 E320 CDI, I love it, although it has the front end bushing issues. I was going to put a OM617 in my 2007 Jeep, but I think I'm goin with a GLK Engine, transmission and transfer case!

how long did it take completely, removal and renewal

I’m located in Clinton Township MI. Do you work on vehicles? I have a 2014 ml350 bluetec and need some work.

Modern mercs are crap! Swithched to porsche Cayenne V8 diesel ⛽️ 👌 🙌

Excellent video but dude, turn the music down or your voice up preferably both. My fingers are worn out from constantly adjusting the volume! 😳

Please assist with suggestions; had to replace the cracked nozzle cover for W203 CDI now it looks like we have damaged the threads where you screw back the injector holder. thank you in advance .

Which direction did you move the arm to for the EGR valves to be constantly open? Forth toward the front of the engine or back?

hi you have great knowledge in this OM651 engine, can you show the location of the EGR please?

Totally normal, newer diesels has vacuum/venting pumps pressurizing the crank case apparently. Dont worry about it

Block off the line from the vacuum pump. The vac pump vents into the crank case and causes weird "blow by". If you block off the outlet ports on the vacuum pump and it still does it you may have a issue. But tbh the crank case venting on some of these 4cylinder diesels isnt the greatest.

My dad scared me when he told me check the oil cap and it was doing the same thing. I just bought a e250 with 90k miles. Dealer maintain. Mine runs great and no check engine light

search "diesel blowby" on youtube and you will see real blowby

Thats ok. I went nuts with the blowby on mine. Its been years now and still runs fine.

is PCV valve ok?

The first time I did this job, it took all day and I got my arm burned on the exhaust somehow. The second time I was prepared and it took under 2 hours, taking my time.

i live my life happy again after selling my mercedes with om651

By the way, this was an awesome video! Very informative

I have a 2014 GLK250 with 160K miles. It's an amazing engine. Unbelievable power for a small diesel, great fuel economy and 100% reliable.

Very good video, I bought a GLK250 with 180k miles back in march. Now it has 187k miles I have replaced the intercooler hose along with the boost elbow, and the intake pipe.

Hey man, first thing first - absolutely love your channel man. Some stuff you explain is priceless. On another hand, I was thinking to buy this scanner and then i saw all negative reviews on Amazon. People use it, there is an update, people do update it and then "repurchasing" option pups up and manufacturer is ignoring customers. So my isssue is that it will work for unknown period of time and then it becomes paper weight. Can you recommend any other brand please?

Great information on this repair! When do you replace vs reuse the oil cooler? There’s 2 aftermarket coolers from China available and 1 Mercedes from Germany, what’s your thoughts? How do you cleanup those manifolds, they look new? Many thanks.

Considering a used Mercedes and trying to educate myself on these engines, this was a very valuable video for me. Thanks!

I see quite a bit of surface rust. Do you think the rust caused the ring to bond to the inner knuckle after it being left parked for a while?

I just had the check engine light on for the last 2 days and its the o2 sensor. Car has 68000kms

My oilcap on my s205 250d is also leaking 😅

I am trying to configure an android radio but as I see there is none canbus version I dont Know Why.I connect a long green (one with a red Stripe and the other without) in the can bus location near left driver in the floor but can set it to be detected.My car is 2006 e320 cdi.thanks for your help.

can I get an email for you please I have a lot questions ... mine has lost power and doesn't launch anymore

Brilliant video. Thank You I think the ABs Rings on these fail much quicker than the sensor

I have a 2014 E250 bluetec im gonna help some family with, we have the code that shows the switch over valve, the controller for the water pump vacuum control thing, we just ordered the special change over valve 002 540 14 97 part number, but no idea how to get to it. I have seen it done on some mercedes sprinter vans and even smart cars have this exact valve but theres some other tubes and pipes in the way. Im thinking of just loosening the clamps that hold those other tubes so i dont have to remove the ones above and around it just to get to it... If you can think of any videos showing this being done please let me know

Was looking at VW TDI NOW IM LOOKING FOR A 648! GREAT VIDEO

my w211 front shocks still say "04" :D

My car smokes on idle not the turbo could this be the issue

If the engine runs... is this the cause why the OM642 turns of during driving? Diesel tank is at 3/4 capacity and my engine went off when i let it off the gas at 150km/h the rpm went to zero. I only noticed it as the gearbox went into Neutral and the car coasted restarted the OM642 and while coasting it was idling nice switched to drive and cluster showed "D" Cluster shoed Gear 7 (G9 Gearbox) at 100km/h and made the car drive again normal.. you can imagine my pulse going way up on the autobahn..

Hi does "stored" on my foxwell scanner mean the fault is still there? Stored(event) Stored&current Stored&current (event) Please tell me the difference

So glad I found your channel!!!!!!!!!!!! 🌟⭐⭐🤩

Great video !! and a nice efficient engine. On my GLK (rear drive, 200CDI, no adblue) - only had 2 problems: intercooler air hose (black one) - typical crack and eventual burst takes place typically after 70k miles and is easy to replace, the other one is Mass Air Flow Sensor (MAF) mulfunction - and I will attepmt to clean it myself using MAF cleaner - hopefully I'll get itback to normal operation, otherise - need to replace.

Om606 was the ultimate diesel mate

Great video. I’m in the process of doing this job and decided to delete the swirl flaps. I have the 2 magnet sensors as mine is a 2014. Do you know if putting the wire in the 2 middle slots will still work for mine or is there an additional step I need to take. Thanks in advance.

trés bonne explication j'attaque demain sur ma e220cdi Merci

thanks, wish i watched this before dismantling, i didn't remove the firewall, is was a pain in the ass to get the turbo off....

Do you know if the NT530 will measure or display fuel pressure? I’m having long starts on my OM642.

Do you happen to know the part code for the new o-ring?

ahahah holy crap man....nyou weren't kidding, just removed mine and took a bit to get it out..... heck of a job man, replacing both front with sachs parts....great video man!!!! many thanks

My OM651 has 198 000 km on it. I have done two things on it except regular maintenance. 1) Tightened the 12 (?) bolts on the valve cover. It's made of plastic an without metal inserts for the bolts. So how long will they keep the tension....it leaked quite a lot. 2) Changed the DPF diff pressure sensor. Very easy to do. I love the 2010 C-class, but of course don't like to think about all the plastic parts in there. I can only hope for the best, and keep changing the oil every 8000 km. I plan to change the transmission oil this summer. It was last changed at 60 000km. 😮😮😮

The OM642 is known for stuck oil rings, they can easily burn a liter per 300 miles.

can you tell me at what mileage should i get this done on my ml350 bluetec 2015

Engine is great the emission system was a pain in the butt. Twice a year a trip to the dealer for NOx sensors. Finaly gave up and the DPF fell off. No more problems.

First can is the DOC and the second one is the DPF

Hello, did it improved something?
