12 c63 p31 with about 1800 miles on it... From cold start heard this odd clicking sound from the engine... Went away after driving for a little while and oil to temp and didn't happen after next start... Any ideas?

Thanks

Normal.

Lifters. Use 5w40.

Like the others have said, just your lifters. Go get a few Liters of 5w40 and top off your oil until it's between the two red marks. My 63 had this ticking sound this morning, added 1L and it went away.

If it continues, record it and post it here for us to hear exactly what kind of noise. Should be a simple fix as stated above.

Did your car sit for a couple of days before you started it?

AMGeer

So far the sound hasn't come back... The lifter explanation makes sense ... The car hadn't sat for a while ... Just overnight ... I did run the car pretty hard the night before...

Thanks for all the input ... Very helpful stuff

Why not 0w40?

manuel009

always happen when the car stay sit for sometime. to me happen every time i start my els. on c63 never happen, but just because i use it as daily driver.

0W40 hasn't been used in the M156 for years.. Some dealers in the states are still using it for some reason. Its too thin and leaks out of the lifters when they are sitting..

I don't believe this to be true. My dealer is an AMG centre and they told me to use 0w40.

The ticking sound is the lifters, goes away after you start driving for a little bit.

My dealer is an AMG centre and they told me to use 5w40.

There was a TSB a long while ago telling all dealers to stop using 0W40 in M156 motors and use only 5W40.

My dealer had no clue till he pulled up the TSB from 3 years back. He said oops I must have missed it.

This is why I do my own oil changes.

You should have your dealer double check... mine uses 5W40 for our cars.

I'm not sure what our stock oil was when it was built, but my dealer uses 5W40 for my oil changes.

I really believe its part of the break-in process. I had mine do the same thing at around the same miles but it never happened again. I'm now at 2400. It would be interesting to find out if yours will come back.

Merc63

Mine too. My good friend is an AMG tech. They haven't used 0w40 for years.


Maybe these guys don't know how to read?

Google hydraulic lifters. You will see why you don't want to use a oil too thin like 0w40. It leaks out of the lifters.

Can someone post the contents of the TSB please. I have been reading various 0 vs 5 threads for a while now..... It is time to put this argument to bed.. and for that.. we need proof. Someone post the proof (I can no longer access http://www.startekinfo.com/StarTek/)...

balthaser

Can Anyone pull out the TSB number and content about changing from 0w40 to 5w40?

I might need to go do oil change tmr

Noted elsewhere I had clicking and rattling now attributed to (ready for this?) washing the grill with a sponge. The grill once came loose. The clips holding the grill are not up to it. The sound was like dry lifters or loose pulley. Only happened twice. There is sometimes the faint sound of lifter noise which quickly subsides.

Is this a sound you can hear from inside the cabin? Or do you need to pop the hood?

Haven't heard this since I bought the car. My dealer says mobile 1 5w40.

Jons95c36amg

Its normal on very low mileage C63. I always use 5-40 mobil 1. Had ticking sound way back. Now with 25k+miles no more ticking sound.

Merc63

My grill is broken off on the passenger side too.

Damn cheap plastic bolts
