Hi Guys,
I had the EOBD Engine management light come on in my 156 2 months ago. Read the code and got P1177. Cleared the fault and the light stayed off, until Yesterday. Read the code this morning and got P1178 – unknown code. Cleared the fault and the light is still off. From what I have read on here I’m thinking MAF?? Cambelt was done 10k / 19 months ago. Strange thing is the car is running perfect.
What do you guys think?

That was one of the threads I had read, which made me think MAF problem. The bit that is confusing me is the car has no symptoms. There is no loss of power, no rough spots, nothing. Also took a quick peek at the cambelt and it seems tight.
