Sorry for posting her but I need help

[Chris5.5]

Had a passat tdi sport, that I sold in June as I was getting a company car. Got a saab sportwagon, the 150 diesel is a peach but the interior is nowhere near a match for my old passat.

Anyway bought the wife an x reg 2.0 golf as a run around as I like vws (didnt post in the others section as it is like a ghost town)

The emissions light keeps coming on with a p1128 code, I have changed the maf but it still came on after the local garage I bought it from reset it. Does any one have any idea what else it could be.

Any help would be much appreciated

Thanks

Chris
