Faulty throttle potentiometer?

[Gubien]

Does anyone know if block 062 is the correct block to see if the throttle potentiometer is doing it's job ok?

Here is a log in 3'th gear with pedal fully clamped. But dont know if its the right block

Btw. The EPC light comes on when turning to ignition, after a like 5 seconds some of the lamps dissapers, but EPC stays on with the battery light etc. until I start the car. Is this normal?

Not normal no

 

[Gubien]

Hmmm... might be the reason why my car is not boosting correctly! Odd thing i though that vagcom does not show any errors at all.

 

[Gubien]

So when turning to the ignition setting, all icon lid up and the EPC, Battery, "green light thing", parking brake and the Engine remains on until I start op the engine. I guess the others are normal? But not EPC?

 

[Willie]

Yup, everything on for a start then everything off straight after starting apart from the parking brake

 

[Gubien]

So the EPC icon should dissapear shortly after is was lid? (The icon is not there when the car has been started up)

I think the 77,7% from the third collum is a bit low, can anyone confirm that? I read on a TT forum that the fourth collum should be the half of the third. So 38,7 seems ok.

But they also talked about a tolerance of 12-97% Which in my case i lacking 20%! Does anyone have the opportunity to test this on a LCR?

 

[Gubien]

This was what I found on a TT forum:

ECU Block 062 – Accelerator Pedal
The DBW accerelator pedal has two position senders, G79 and G185, in a joint housing. The sender potentiometers are connected so that the voltage from G79 is twice the voltage from G185. The ECU converts the voltage values to percentage values, 5V corresponding to 100%.

Enter the ECU Measuring Block 062.
Press the accelator pedal slowly. The values in fields 3 and 4 should increase steadily. The tolerance ranges are 12% … 97% and 4% … 49%, respectively.
Check that the value in field 4 is about half of the value in field 3.

Come on, there must be someone with 15 minutes of sparetime and vagcom (
