Hi,
really need some help.
about a month ago my CEL came on. my friend checked it with his snap on scanner and it came up with the P0441 evap code and a maf sensor code which im afraid I cant remember. he cleaned the maf and cleared the codes but they came back, so I tried replacing the charcoal canister, but they came back again. I have now had the car checked with vag com and the only code that comes up is P2187 system too lean at idle. im not sure which direction to go in, do I replace the maf, or maybe the n80 valve or double check valve or maybe even the injectors. it does have a seriously loud tick when I accelerate and when its idling, which I had vw look at quite a while ago, they said it was just loud injectors and normal.
any help would be appreciated.
