2005 CLK320 Shaking when creeping in drive and reverse
Hi everyone. I am a long time fan and first time poster.
So, the car is shaking when you are in drive or reverse and you slightly let go of the brake and creep. This usually happens at stop lights. Sometimes the shaking gets so bad and hits a perfect pitch and makes your head bobble back.
I took it to a indy and he thought it was the motor mounts. He changed the motor and tranny mounts and it made no difference. I asked if it could be the maf and he said there were no codes to make him think anything wrong with the engine or exhaust system. He then said the shaking was normal when creeping, I said no, so he took out the mounts and put the old ones back in.
I took out the maf myself based on a guide I found and cleaned it with maf cleaner. While cleaning, I noticed a brown rubber like square border type ring on the maf was cracked. Can this cause the symptom (and not be enough to cause error codes or cel?)
Also, any suggestions on getting this shaking fixed? I've read it could be build up in the cylinders, spark plugs, coils, maf.... Also, there was shaking before but that was because of bent wheels and it went away after I got the wheels straigtened. I don't think this is tires/wheels because sometimes it will shake before the car even moves.
BTW, I attached a picture of a maf that shows the brown rubbel seal ring thing. Mine would look the same but cracked.

Suggest you find out what codes the car is storing first & post.
There is an excellent chance that it is the MAF
Check Plugs, coilpacks & wires
Check all breathers & EGR circuit for blockage.
Check vacuum lines for leaks.
If all else fails check the throttle body.
Good luck!

indy said no codes regarding the engine that would indicate misfiring, bad maf, etc. He said, the car is fine and the shaking is normal.
Thanks for the list of suggestions. Probably going to take it to the dealer and see what they say.
I also ran it to near empty and put in a new tank of 91 gas from shell hoping maybe it was bad gas or something. No change though.

Please find out what the codes are or were. He might not know Benz & a M112 engine should not shake. They are ultra smooth.

Sometimes a bad MAF sensor won't throw codes. If you have rough idle and bad MPG, I think it may point to the MAF. That seal should not be cracked. In fact, I can't imagine what caused it to crack - it shouldn't get hot or be exposed to any chemicals that would deteriorate it. It's going to cost several hundred dollars, but I think I might go ahead and replace the MAF sensor to see if it helps.

Don't try to save a couple bucks and buy those cheap MAF on Ebay. It does not work !!!!!!!!!!! Buy OEM MAF ONLY.

+3^^^^ & Rodney is spot on. Frequently MAF's throw no codes. Only maybe a fuel trim code when they are chronic.

Spark plugs shouldn't need to be changed until closer to 100K. Plug wires can go bad, as can coil packs. Usually if a coil pack goes bad, you'll get an MIL with misfire codes. A single bad plug wire might not throw a code.

Hi guys,
Thanks for all the advice and support. Car is back and smooth as silk. The dealership ended up changing all the spark plugs and a couple wires. There was no cel ever and the SA claims there were some misfire codes (although indy's machine never picked these up). I guess the crack in the maf seal is superficial enough not to be causing the shaking.
I hope this thread helps other owners. Even though the car is 7 years old, its still a benz and should run like spec.
Cost was about $800 (after negotiation) for full diagnosis and repair with loaner car for 3 days.

P0303 and P0353 are errors relating to firing of the #3 cylinder. Maybe you don't have that coil installed correctly? P0016 could be symptom of the dreaded balance shaft failure, but it could be somethings else since it relates to about three different MBZ engine DTCs. You need to get the codes read with SDS to get the true DTCs - if that P0016 is a DTC 1208, then you have balance shaft issues.
