Hi everyone,
I looked at an Audi A4 B8 2008 2,0 TDI Diesel during the week which had the EML light on. The log from the ECM is attached. I had a throttle body from the same type of car and engine so I changed them but the DTC remains. The throttle which is originally in the car is made by Continental and the replacement is made by Siemens. It appears one of the part numbers (starting with 03L) has been covered or not printed on the throttle body on the car, the date also is 08.06.2015 suggesting it has also been replaced in the past. I ran three new wires of the 5 which go to the throttle body (2 wires for the dc motor for the flap). Problem still there. I have also taken logs of the adv measuring blocks after trying something different.
I then looked at the adv measuring blocks of another Audi with the same engine, the value for throttle valve position sensor was ~2200 mV at idle compared to the ~4300 mV I'm getting on the car with the DTC. When I replaced the wire for the signal off the throttle I measured what voltage was on the old wire to see if it was shorting with the 12V however it was 0V. I also checked the voltage on the signal wire and it is the same as what the ECM is measuring
I can only hope the only solution is to get the identical replacement part as there must be an internal fault in the sensor.
Any suggestions ?
