This may sound funny, but be careful kicking off wheels when they are stuck on the hub. I've been doing it long enough to see all kinds of crazy things happen. Simple solution: just thread one lug bolt back in a couple turns to act as a tether from the wheel going crazy once removed. It's also a bit easier to donkey kick it from the back, much more leverage, and almost 100% successful for me at least. My coworker had a wheel bounce back up and hit him in the chin. I had a stuck wheel fall off while I was turning the opposite wheel with it up in the air, the wheel fell off the hub on an angle, ricocheted back and put a big old dent in the fender.

[@Angl0sax0nknight]

I always found it better to leave one bolt on the hub loose and use a rubber mallet to pound the tire off.

These engines are well known for cylinder scoring. Usually the engine still runs normally but eventually it starts burning oil because the oil rings on the pistons cant get into these scared up cylinder walls. People start to sell such cars with oil burning of at least 1 Liter/10000km here in germany when they get around 80.000-120.000km and sadly it just gets worse exponentially. In america you might get away with just topping up your oil every x miles you drive, but keep in mind that emission regulations in germany are very strict and vehicles are being tested every 2 years

[@mykolapliashechnykov8701]

These cars should last much longer in the US. The speed limits are low so the engine doesn't overheat/warp as quickly. Also the oil changes are much more frequent. But for the quality standpoint yes, this is an unmitigated disaster.

[@Hi.Al.]

It's called strict regulations but is actually sustained scam to trick people in dumping there cars and buying a new one that has even worse quality 😢

[@ApoloKabali]

Same in California, we do fix emissions controls still alot of vehicles fail, those cylinder scratches will still cause oil leaks and burning.

[@mykolapliashechnykov8701]

@@ApoloKabali It could be fixed by reverting the manufacturing back to the cast iron blocks and heavier, sturdier pistons with wider piston rings. Those engines won't be nearly as responsive or efficient but they'll last forever without scoring. But that's no longer possible, for multiple reasons.

A couple things to help you out. I did exactly that repair on a customers car last week. Firstly, the programming code for the injector amounts is on the connector of the injector itself (check the instructions that came in the Bosch box). That needs to be updated into the ECU. Secondly, oil wicking happens not only from the camshaft adjuster solenoids, but also from the camshaft positioning sensors. It is recommended to replace all four of each. While you're at it, the front timing covers usually leak and contaminate the ancillaries below like the alternator, which I had to replace once on another car because of that. Also very common for this engine is a bad PCV/AOS combo for partial and full throttle. Those are two different components. One is the black plastic box on the bank 2 valve cover with the hose leading to the intake pipe and the other one is the cover plate and centrifuge behind the bank 1 cylinder head. Also, have a look at the engine mounts. They are always toast on these vehicles.

Modern cars require a different kind of mechanic. There are still plenty of mechanical bits to work on, but really you need the brain of an electrical engineer added in. So much of modern mechanics is not just to read error codes, but using tools to then isolate what that code means. A mechanic who can do amazing things with a classic car might be pretty hopeless solving issues with a modern car (the reverse is also true). Thanks for the great story telling. You do such a great job explaining what you are doing and why.

I do think a lot of these engines get condemned because of visual bore scoring. MB does have a bulletin showing you to identify "severe" scoring from normal scoring. If you examine the bores of a perfectly running M278 or M157, I am told they will all show some scoring. It's the compression that matters. And some of them WILL drop compression in severe cases, and also present with an audible tick from piston slap. And I would seriously consider just doing the other injectors at this point. Don't forget to code them in.

A couple of things for you to know. 1. On the m278, it's usually the camshaft sensors that push the oil into the harness. Replace them 2. With that cylinder scoring, the mechanic recommended engine replacement because it'll burn lots of oil which will also damage the cats. Usually it doesn't misfire, it's an oil consumption concern.

Resistance checking a circuit is not a guarantee that a circuit is good. Most multimeters are sensitive enough that they will show a "good" low resistance circuit with just one strand of copper left, or even if both ends of a completely broken wire happen to touch. A good alternative test, in most cases is load testing the circuit. Such as wiring in an old sealed beam headlight. They don't take a ton of current to power, but its enough to fail a poor connection and it will either be dim or not shine at all.

Previous BMW had a broken turbo on 300.000 km (Garrett) and is now on 800.000 km according to the last time I spoke with the new owner. Seeing this video I would say many bad mechanics that do not know how to deal with a bit more advanced engines. Good to show videos like this!

[@extraglutenplz3758]

its pretty well known that many (not all) german car's have robust engines, its everything surrounding it that goes bad and needs replacing.

[@Angl0sax0nknight]

I’ve been a European auto tech since I was like 19. I started on Mercedes but moved to BMW. Just liked BMW engineering compared to newer Mercedes. I can’t stand Audi engineering and despise those cars.

[@funnykiasedona1077]

21:21 this is partly true because of ecu matching or part matching (i don’t remember the name but it’s basically the entire “right to repair” debate)

[@Applepro90]

Waldo is amazing man. He does all his own work with all his equipment. Love this channel.

[@bobbymunyavi5357]

Seeing Waldo at work and comparing to the mechanics in my country shows me why cars don't leave the garage this side.

[@zollotech]

Love the series idea. Great video and Merry Christmas

[@WaldosWorld]

Thanks, Merry Christmas!

[@stuart6973]

Great video 👌🏻 Merry Christmas from 🇬🇧

Merry Christmas Waldo...May God be with you and your loved ones!

[@WaldosWorld]

Merry Christmas!

[@jamesjenkins4872]

Waldo doesn't everything right ! Really go's the extra mile I really appreciate watching his videos wish he was my mechanic

[@AstridRohan]

Great video. I'm new to car stuff, but because of the clear and concise way you went through your troubleshooting, I understood what was going on the whole time.

[@mo3bius58]

It would have been interesting to see the signals from the new ECU. I am pretty sure you are right with the interpretation how the signals should look like. Still, better to verify ;)

[@wallysprint]

0:59 "Waldo, KZbin Certified Mercedes Techincian" 😯😯😯

[@MotaDhesi]

Haha. That's very misleading. Some stupid people are going to believe it.

[@TheFalseShepphard]

​@@MotaDhesi too bad

[@ArtistryAuto]

Im a mercedes benz tech, Almost certain you didnt need an ECU, from what you showed the ecu nor the cam magnets had oil in the harness. When you swapped cyl 5 Injector you took a picture of the wrong code. the code coding injector is at the connector of the injector not at the bottom. Thats why you got a code for the injector but had no misfire. Im guessing when you cloned the ecu it kinda coded itself. ps loved the video

[@Thecar_55]

as a MB tech i agree

[@connornusser-mclemore631]

as a guy who’s never worked on a mercedes i agree

[@G30MaxForce]

I have no clue...but this make sense.

[@dangoodall-williams4200]

Always great to see you. Knowledge + correct tools=correct diagnosis! Brilliant! Side note: I saw you and ARV's videos today!

[@duckbow]

More of this! Great job and would love to see this as a series. If I was in automotive repair school, i would make this required viewing for the diagnostics and problem solving skills alone.

[@fahisaurus]

Warning about anti seize: literally says on the bottle "not for use on wheel lug nut or stud applications". Use something like blue Loctite. It will also not affect the required torque value.

[@Jacklsovakia1]

had to do a double take when he did that. we joke about doing that but absolutely never will I put a lubricant on a lug nut.

[@Ben-in6qh]

But when you are taking them on and off and actually checking them like he will they'll be just fine

[@tdotw77]

This is the salt-belt. We anti-seize them to be able to remove them again. I put anti-seize on all 8 lugs on all 4 wheels.....never lost a wheel or had one lug loosen up on a 9000lb diesel truck. Warnings are to protect the company from lawsuits....it also says 'don't injest or inhale' too!

[@Jacklsovakia1]

@@tdotw77 I live in the salt belt too. may be different if you're talking about a semi or something, but not on passenger stuff. for me, on the hubs sure but not the studs

[@Jacklsovakia1]

@@Ben-in6qh but he won't clean it off before he sells it. don't know about your people but I know for sure most people aren't going to re-torque down the road. lucky if people even check their air, muchless rotate or torque on a regular basis

[@dextec49]

Wow, misdiagnosis is a big problem for customers. Glad you are doing videos on how to fix problems on these cars. Nice Christmas present for you. Happy Christmas and holidays.

[@pskin1978]

Great video Waldo!

[@LivingWaterEternal]

Most people do not care to take the time nor do they job correctly. It is a shame the other guy got the push around. I hope you do something good for others for the generosity of the car given to you. Great video always. Thanks and Merry Christmas and Happy New Year.

[@BXtremP]

Keeping an eye on your channel since the Dynahoe project, and I have to say I'm happy that your channel has evolved both in numbers of viewers, but also in quality of video. You really have improved yourself in the past years to offer some interesting and well-shot content with good explanations, like Chris Fix for instance. Good job Waldo, and merry christmas!

[@WaldosWorld]

An OG! Thanks, and Merry Christmas!

[@peterhaynos7132]

Gasoline engines need 5 things to run 1 Air 2 compression 3 fuel 4 spark 5 timing

[@FASTECAUTO]

Actually 6 things FUEL AIR SPARK TIMING EXHAUST COMPRESSION 😅😅😅😅

[@russbuzzell7013]

Looks like you need a gooseneck trailer.

[@robertavellinoamericanpatr6287]

I had that ECU diagnosed right from the get-go as soon as he said there was oil around the ECU I knew it was bad

[@takiman1]

Good for you

[@michaeldebrou7793]

I would suggest offering the car back to the generous previous owner for the cost of your time, parts used and fuel etc. and filming his reaction. Should make for a great video! You are super thorough and knowledgeable!

[@JakeSpeed1000]

Or, they just wanted to sell them a new engine. I needed a timing chain repair on my Cadillac STS and took it to the stealership. They said it needed a new engine. I took it to a reputable independent repair shop and they fixed it for $1200 and it has run fine for a year now.

[@wholeNwon]

An example of why I never go to a dealer for anything other than warranty work. Sabotage isn't unheard of either.

[@Macjeg0815]

Holy cow I have two of those and I was praying you made a video of this car!crazy as hell you did! This is so crazy bc this is such a random Benz

[@Starting_over-cc8ib]

2.7 tons? You’re telling me a high end soccer mom suv probably weighs more than my medium size pickup? I know my place now

[@WaldosWorld]

Yeah 😂

[@N911GT2]

Makes sense en pickup is just a bed. This is full interior…

[@andersnilsson973]

Because the pickups are cheap crap, this car is not.

[@kevinnolan1617]

Genius Waldo. Many main dealers seem to want to charge huge bills for nothing. Always best to use a Mercedes specialist. Keep up the good work. PS, why not do a full service on a Mack, Peterbilt, or Volvo automatic tractor unit. We all love trucks, the bigger the better. Kevin

[@jamesanderson84]

Great meticulous diagnosis. Logical. Easy to follow. Although Waldo has a LOT of tools that most people don’t possess so not easy to replicate what he does.

[@Jcool2018]

Problems with the tire machine and the impact? It didn’t even sound right. Maybe you need to take a look at your air compressor.

[@WaldosWorld]

Yeah, the temperature was so far below freezing that there might've been some ice restricting the line somewhere 🤷‍♂️
