C63 check engine light help

[Osgee]

Hi all

Recently I have had my check engine light come on .....then it went off after a day and now its back on. Both times I was driving the car in a very normal manner not hooning it about,

The car drives fine but seems to pop and crackle from the exhaust a little bit more than normal (you only normally notice that when having a spirited drive not a normal commute)

When cold if you rev the car even a little it sounds like its only firing on 7 cylinders but after 30-40 seconds its fine

Going to take the car to mercedes asap but just seeing if anyone had any ideas?

The car has recently been mapped ..... could this be related or is it just coincidence ? What are the symptoms of a dirty maf or bad coil pack ? The car is a 2008 c63 with 40k on it

Cheers guys

Could be 101 things, fault codes need to be read.

Who mapped it?

Dynodrive but I think they use Viezu software, I dont think that is the issue but they are taking a look at the car to see what it is, got a feeling its a dirty/faulty Maf or coil pack , what are the known symptoms of these going faulty ?

Ok had it rigged up to a star system and this was the result:

* 0745 - Self-adaption of mixture formulation for enrichment at idle for the right cylinder bank is above the permissible limit (P2187)
