The dreaded M272 Balance Shaft
#478
Fault Code: P1200 or P1208 Pending or Stored
Fault codes 0059, 0060, 0063, 0064, 0271, 0272, 0275, and 0276. These fault codes could be recorded as current in the ECU fault memory. If current or pending these codes are caused by a malfunctioning camshaft adjustment solenoid. If you have these codes you should check for oil leak at camshaft adjustment solenoid.

I received a call today from corporate basically telling me my engine was not affected by the balance shaft issue and that they will not offer a good will repair on the balance shaft.
Any other suggestions that may get them to budge?

I had the it checked for oil leakage st the camshaft and there was nothing. I had it confirmed with the MB dealer that my balance shaft needs to be replaced. I brought up the class action and the service manager said I needed to speak with corporate.

Thanks to everybody! Before I bought it at second hand, 3 years ago, I check the VIN code... and I believe it not have that kind of problems... but now with the P002x errors I start to be very worried... and now with the P0020 it is hard to find info about that error on M272... I thought it could be Hall sensor, but error sensor code ends at P0019... ( In some places I read that in one C class that kind of problems was by the alternator... I will try... or perhaps any other sensor like detonation of sparks? or temperature ? I have Wiss and Anra installed at home, but I cant look for DTC codes... It is any way to check it? Perhaps it is time to update my OBD2 adapter... ¿Any recommend of good OBD2 adapter with bluetooth to use with android for Mercedes Cars?
thanks!
thanks!

I have a 2007 ML350. Purchased it just passed the extended warranty expired. Ended up getting the codes popped up. Now i'm stuck doing the work myself. (the dealers nor MB USA will not lift a finger to help)
I'm at the point of removing the shaft but, realized i should change the chain as well.
Can't seem to get the Guide Rail Pins out.
anyone out there know how much force is needed to "slide-hammer" them out?
thanks,

I recommend using a bolt insert against a plate that pulls the rail guide pin out rather than a slide hammer. Kits are cheap- but you can fabricate it with pieces from a hardware store for a few bucks.

206 c280 4matic engine swap
Can anyone here shed some light on an engine swap? I have a 2006 C280 4matic with the dreaded m272 balance shaft issue. The car has 83k on it...still runs ok but is getting noisy and cam codes stay on. Will a 3.0 engine from a 2009 C300 work in my car. They are plentiful in my area and reasonably cheap. They appear to be identical, but I'm hoping someone here with more knowledge than me can help.
Any info would be greatly appreciated.

I just did this idler gear / sprocket replacement on a 07 CLS550. A couple of points.
- Engine doesn’t have to come out on a V8 but you would be crazy not to. I was. You end up having to disconnect everything except 4 bolts and you will probably spend 20 extra hours if not.
- Engine has to be pulled in a V6. You have to get to the back of the engine.
- The V8 gear and the V6 balance shaft have teeth The are not hardened. The chain eats the teeth. These 10% affected claims are nonsense. Good luck proving that unless there is a hidden document that alternate suppliers provided hardened gears.
- The rear camshaft plugs leak and are a cheap and easy fix.
- The front camshaft sensor O rings can leak and are an easy replacement.
- The front camshaft adjusters leak/break and are a cheap and relatively easy fix. One is a bit of a pain because the oil housing has to come off but no big deal.
- The vacuum operated lever on front of intake manifold can break and is an easy fix if the manifold is off.
That’s everything I can think of right now.

How can I know if 2006 E350 balance shaft was fixed by PO?
How can I know if the previous owner(s) had the balance shaft issue fixed? The car has been repossessed by a bank so I don't have any access to the previous owner or service records. It currently has error codes of P0016 and P0017. Mileage almost 200,000. Starts easily and idles smooth. Thanks so much.

If the repair has been done, it should not show the codes, as surely the repair mechanic would have cleared them. Those codes indicate possible balance shaft issues.
There is a YouTube video here that shows how to check visually. However, the fact that the codes show is a real issue. The cost of repair on the balance shaft is high-maybe the former owner just decided to let it go back to the bank?

Try to disregard the techno-music!
This won't really say that the repair has been done, but it should indicate whether there is a balance shaft problem. The teeth on the defective balance shaft sprocket get worn, and that throws off the positioning of the timing chain, as I understand it, thus throwing the code.
The cost of the repair is usually over $5000. That often essentially totals the car. I had to have the repair on my 2007 E350. My wife has a 2006 E350, but relatively low miles, so no issue has popped up yet. Keeping fingers crossed. We are seeing more and more of these at higher mileage.

The parts aren't that expensive a little over $400, but you have to remove the engine in order to replace it so a lot of it is just labor. There are reports of indy shops doing it for around 3k but there are also reports of indy shops doing it and then it doesn't quite run right afterwards. If the mileage is high, I'd also think about replacing the intake manifold too as those are known to go.

I don't know what the purchase price being asked is, but if the balance shaft needs replacing, there may not be a lot of value there on a 2006. Be really careful.
