My Turbo Diesel Mercedes Has A Nasty Engine Issue. Don't Buy A Diesel Before Watching This video.

Factory Style Workshop Repair Manuals bit.ly/3l2k9WO
The real reason my CDI Turbo Diesel Mercedes was and still is the cheapest in the country is because of a horrible engine problem. If left untreated this issue could cause catastrophic damage to my engine and render my car worthless. Don't buy a diesel car or truck without watching this video and inspecting for Black Death!!

How much do you think this would have cost at the dealer?

[@ikkem8407]

At least 1500 dollars

Hello legit a question this black death Also could happen to an W210 engine? I mean with those rings seats of the injectors? Thanks and merry christmas from Paraguay :)

[@rvj1126]

At the dealership, about 2500.00 dollars...

I bought a 2006 E320 CDI from copart 3 weeks ago based on Alex's videos. Now i'm investing in tools to be able to fix all the problems on this vehicle. It arrive in limp mode so tranny won't shift out of 1st gear

[@mqbitsko25]

I don't, but I have a VW TDI and this applies. I've always changed the seals periodically, but you never know.

[@jdantigua1999]

The cost at the dealer is minimum $1,200 USD. I know because I did it once. Since then, I invested less than $100 and have all the tools to do it myself. Something else, if you don't have "black death" keep the injector lubed. The injector body is steel and the cylinder head is aluminum - two different metals with different heat and corrosion properties.

This happened to my 2003 sprinter van. The Mercedes dealer told me the problem was caused by bad injectors and I would have to replace all of them. Luckily I knew they were lying . I went to the parts counter , ordered the injector seals and bought some oven cleaner on the way home. I was done by that evening. That 150000 miles ago and @315k my original injectors are still going strong. .

Oven cleaner shouldn't be used on aluminum head.

I used to own a shop a few years ago. I specialized in diesel injectors and pumps. The only thing I'd add to this is; while the injectors are out and since they have a lot of miles on them, take them to a _legitimate Mercedes authorized diesel shop_ (usually one that also works on Frieghtliner trucks) and get the injectors cleaned and calibrated.

Excellent video! Many years ago (1984), I bought a 1965 MB 190D (Heckflosse--Fintail, or Swallowtail) for $600 that had been sitting in a carport behind an old house for years. After towing it home, I was cleaning it when I pulled a threaded rod protruding from the instrument panel (I had put a battery into it to check out the lights and such) and it fired up! I knew nothing about diesels! But I bought a Clymer manual and started doing repairs and maintenance on it. I was actually able to order parts for it from our local Pontiac/Mercedes-Benz dealer (!) A year later, I sold it for $1500 to a guy who just had to have it! I regret selling it to this day, but that money was most of the down payment on our first house... so it was for a good cause! Keep on wrenching, and Merry Christmas!

They snapped off one of the F$%^#@@ long thin retaining bolts and couldn't get the injector out with the correct puller, so the head had to come off, The injector got damaged. SO. . . My boss had a (LOUD) chat with them and they supplied a head set, bolts at cost, a second hand head that came with the injectors which they pulled out of the head for free. (The bottom of the injector hole was too badly eroded to machine up.) We then put it together and the job was done.

A few years ago I had this done on a 5 cylinder Alfa Romeo diesel and a friend who worked at a Mercedes/Alfa dealer did it for me and had me pour Coke over the injectors the night before to dissolve the carbon, I thought he was winding me up but the engine cleaned up easily and all the injectors popped right out!

[@supremacistdawn]

Coke is literally just sugar, artificial food colouring and phosphoric acid, its rust/gunk dissolving properties are well known. Just make sure to rinse it off with water afterwards so you don't get a sticky sugary residue.

[@Zamolxes77]

Coke is an extremely powerful cleaner, in emergency can be used as detergent to wash the floors !

[@pieterdewit9081]

@furiousdriving. You can also use coke for the coolant system. Uninstall the thermostate to gain flow and fill up with pure coke. Also put your heater on. Drive about 50 km's and let it stay in overnight. The next day you can rinse the system.

[@patreilly6826]

I would like to give you a little tip when using a slide hammer to pull a stubborn part. It really helps to have some tension on the shaft of the slide hammer to reduce the bounce effect. The movement seen during your use of the tool shows that you are loosing force that is wasted instead of actually been transferred to the injector. We have modified ours with a ring on the top so we can apply the upward force with a hoist to preload the tool. This reduces the bounce effect and allows for all of the force to actually be applied to the injector from the slide hammer. The hoist does not have to be elaborate or expensive a small block and tackle works well because if you pull on it to tension the ropes the weight of the car will act as a preload. .

You may have saved me some big bucks! I'm a DIY guy, so tackling that job will be somewhat a fun challenge, in case I ever need to do the repair. Made easy after watching this video....THANKS!

PSA for all common rail Diesel owners: this problem can happen on ALL common rail injectors because of the way they seal, keep an eye and a nose on your engine for leaking combustion gasses!

[@slash11lipo]

Alex = Awesome! I watched the whole thing and I don't even have this car nor do I plan to buy one. I simply found it very interesting. Screw you trolls that gave thumbs down!

Thanks Eric!

Great video Alex, learned so much. Thank you.

One crucial thing when using the cutting tools. Pack the cutting end with grease to hold the shavings so they do not drop into the cylinder. The last thing you want after doing a job like this is aluminum shavings chewing up your piston rings and cylinder walls.

[@clarencecrowcarter]

Yes. That freaked me out too!

[@audiguypaul6004]

Soaking the injectors in brake cleaner for days will help dissolve the black death making removal easier, good job though

[@LegitStreetCars]

I soaked them in pb blaster and carb cleaner for 2 days. Those 2 were stuck bad

[@MegaLostOne]

What is to keep any shavings from entering the cylinder when reaming for a new seat? Also what keeps any of the wire bristles from entering the cylinder when using the wire brushes? I am not a mech. but feel this is an honest question, these tools would work perfect if the head is removed but with it still on the block leaves a risk in my opinion. I know when trying to install a Heli-Coil on gas engines the reamer/threader is coated in grease to TRY to prevent anything from entering the cylinder and if using a ream to try to remove carbon build up around where a glow plug would be used in a diesel engine they coat the reamer with grease in order to try and capture any carbon from falling into the cylinder. ,

[@MrShadownoise]

Exactly, use grease, and it's a non-issue in practice.

Great job. Just bought a CDI yesterday. Thanks for sharing.

[@TheKentaurion]

I felt so with You when you struggled with those injectors. Good job!

Great instructive video. I watched enthralled for two reasons: my 17 year old needs to learn about engines for his scooter and I have just bought a Cirrus SR22 plane and believe it or not so much of what you covered is transferable learning. Thanks!!

[@tomrandall4871]

Good video but safety is first! Vacuum air cools the compond motor and sparking brushes. Carb / brake cleaners can be flammable if the right air/cleaner ratio is obtained. And never run a diesel engine with the fuel injector mounting bolt removed! And you had your body over it? You know the extreme pressures that a diesel engine produces? And the pressure that the fuel rail are at? You got very lucky this time! You could loose your eyes and or your life! Please show some respect and concern for people who are learning from your videos. Us old timers have seen a thing or two with hotshot young mechanics who lost eyes, fingers and other body parts because they cut too many corners on safety!

[@5150gino]

Tom Randall thanks for the comment. This is very important

[@deadprivacy]

good point, you can lose an arm or worse, the injector blasts the diesel into your bloodstream like a syringe , even a small amount you can lose a hand ...

[@knocksensor3203]

I would cringe using wire brushes, especially were there’s a potential of some wires coming loose and going inside the cylinder. I would have just used strong solvents and strong rags, picks, small screw drivers. There a very good solvent called Berryman chem-dip ...

[@poppabear3664]

Wire brushes always lose wires, I thought a “Kit” would have included an expanding mandrel to seal the nozzle hole, you could then carry on with whatever methods of cleaning you like, blow the carp out of the injector holes and have a lovely clean head to refit your injectors into.

Good work, enjoyed watching your video and learnt something

[@leso204]

kudos' to you young man' best video of diesel engine repair/maintenance i have seen, i have been a diesel fitter for over 45yr now retired, glad to see no power tools used all hand fit how i was taught, seen too many jobs screwed up by the power-tool mad youth of today very impressed with you work attitude & ethics well done keep up the good work ......

[@colmmcivor9979]

Thanks for the video very informative. My 05 CDI only has 75k and is spotless and I have done all my own maintenance. But you have scared me into pulling my cover again to check for any build up. It’s great to see others appreciating this awesome car. Update. Pulled my cover and mine is spotless.

[@colmmcivor9979]

Will do when the weather warms up a little. Thanks $20 for piece of mind is a no brainier.

Alex, what are your thoughts on the MB 4.0 Diesel V8? I've heard it's an absolutely awful engine, any experience?

[@rafaelrjarquin]

Never heard of it in north America

[@ozgurdeniztuncer5050]

Yeah its true i'm from Germany. This ebgine ist the worst diesel engine in w211. 420 diesel v8 is perfect to buy and use

[@brage4284]

@@ozgurdeniztuncer5050 but isnt it only different injectors and more boost that is different with the 420cdi from 400cdi?

[@ozgurdeniztuncer5050]

@@brage4284 no, 400 cdi has a big Problem with timing chain and timing chain tensioner. 420 cdi has prpblem with oil leak at oil cooler.

Really excellent video. Not a typical American who only says "go ahead" and "awesome" interspersed with the occasional noun. Thank-you.
