w204 c220 Coupe P0299
 

Hello

I have a 2013 W204 C220 Coupe which has been absolutely fine and has thrown a P0299 code.. it goes into limp mode with the EML light on but still drives pretty well although won't kick down.

I've cleared the code and it came back and so remove the turbo inlet feed from the air box to check for impeller play, there's a little but the impeller moves fine and no excessive oil. I've checked all connectors and cleaned the MAF as well.

Hoses seem fine, nothing obvious wrong.

Does anyone have any ideas?

Thanks

Hey,

I have the same symptoms, did you manage to sort?
