Hi All
My A2 1.4 tdi 75 had been suffering from flat performance for past 6 months compared to my previous A2(both non chipped). No engine management light on, and had been recently serviced (full including timing belt water pump thermostat) using genuine VAG parts.
I cleaned out the EGR valve before i started using car (had to sell previous car) so could eliminate this.
The fuel economy was good 54+ so was really lost as to cause of problem.
Always use same fuel and have been using redex diesel cleaner once every 5 fill ups.
When i changed steering wheel out i performed a scan using vcds lite and found this error code
17571 fuel temp sensor (G81) open or short to plus
P1163-35-10 intermittent
After searching the internet there seems to be a common fault with the wiring breaking at the sensor plug (mine had been repaired)
So continued to Check resistance of sensor (very fiddly) with a DVM and found it to be open circuit
Got this info off another vag site:
15 degrees C should read 2700 - 3500 ohms
30 degrees C 1500-2000
80 degrees C 275-375
Since changing this part out 038 906 081 B (£19 main dealer price) the car feels more responsive and revs more freely.
Hope this helps out any members here
