Audi A4 1.9 TDI 130 Erratic idle

[eldottore]

Hello,
I have an erratic engine(AWX) idle problem when the car is warmed up, when the car is cold it idles ok. I have diagnosed the car with the Ross-tech tool, no fault codes showing. i did notice that the MAF sensor reading was erratic also, could the MAF sensor be at fault? Any ideas would be greatly welcomed!

Not sure about your car in particular but after reading a few posts on this and other VAG sites, the MAF sensor is the usual place to start with strange running problems.
Good luck and welcome.
