I have had a problem with the MAF giving me error code P1155 so I brought a new one today, put it on and reset all the codes. Started the engine and it came back along with a Camshaft position A which is a new sensor a few weeks ago, this error hasn't been back since I replaced that sensor. But the MAF seems to have brought it back.
Any ideas why I'm still getting the above error and what I can do about it?
Car is a 2001 330ci M54 engine.
