Golf IV Variant 2003
Engine BCB

EPC light lits first - after a while Engine light comes on.
After restart - no MIL.
Fault code: 17950 - Angle Sensor 1 for Throttle Actuator (G187): Implausible Signal

Below I have erased the fault vode - the rest looks like this - after couple of test drives - the MIL on again:

The Throttle body is changed sometime before - VDO.
And Measuring block 062 looks like this with resting accelerator pedal - engine off:

Code:
17:18:08 Group 062: Electronic Throttle (Sensor Values)
  4.9 %  Throttle Valve Sensor 1 (G187)
  94.4 %  Throttle Valve Sensor 2 (G188)
  14.0 %  Accel. Pedal Pos. Sensor 1 (G79)
  14.0 %  Accel. Pedal Pos. Sensor 2 (G185)

17:18:08 Group 060: Electronic Throttle (Throttle Body Alignment)
  4.9 %  Throttle Valve Sensor 1 (G187)
  94.0 %  Throttle Valve Sensor 2 (G188)
  12.0  Throttle Valve Steps Counter
  ADP. O.K.  Throttle Body Alignment Status

17:18:08 Group 061: Electronic Throttle
  0 /min  Engine Speed (G28)
     Battery Voltage (Terminal 30)
  27.1 %  Throttle Valve Angle 
     00000  Operating Condition
And with pedal on floor

Code:
17:20:28 Group 062: Electronic Throttle (Sensor Values)
  4.9 %  Throttle Valve Sensor 1 (G187)
  94.0 %  Throttle Valve Sensor 2 (G188)
  79.0 %  Accel. Pedal Pos. Sensor 1 (G79)
  78.0 %  Accel. Pedal Pos. Sensor 2 (G185)
% on both pedal position sensor 1 and 2 are the same! (Throttle position sensors % were moving as they should - this above was measured with engine off)
Is the pedal sensor known to go bad or is there somewhere alse I should take a look before changing the pedal/sensor?
Can the sensor be fixed?

Thanks
