Check Engine + Vag codes - Too Lean/Implausable

[ulfilias]

Hi Guys,

I have a few engine codes left from vagcom, which i guess are keeping my check engine light on (I regularly look under the bonet and yep. Its still there)

17549 - Load Calculation Cross Check : Implausable Value
17536 - Fuel Trim: Bank 1 (Mult): System too lean
17538 - Fuel Trim: Bank 2 (Mult): System too lean

Doing some searching i found this http://www.tyresmoke.net/forum/audi-...ror-codes.html with our very own Tony....But no solution

In other checks cleaning the MAF sensor comes up and i've did that the other day, not that it looked that bad. I guess it may be worth testing the performance of the MAF, VAGCOM ??? but i'm not sure what i'm looking for and searching on 3 letters is tricky !

Any ideas, hints pointers ???

Ta,
Lee
