Throttle Body Alignment (TBA) - without VCDS
Had the wiper motor changed - the ECU and battery was disconnected
Car in limp mode with following codes :
#1) 17987 - Throttleactuator - adaptation not started. Code 17987
17987/P1579/005497 - Ross-Tech Wiki
#2) 17951 - Angle Sensor 1 for Throttle Actuator (G187)
#3) 17580 - AngleSensor 2 for Throttle Actuator (G188), Signal too Low
Audi A4 B5 1999 Auto
Can clear the codes with handheld but unable to turn off ECU light and limp mode. The same above codes keep coming back...
This happened once before and we cleaned the TB - worked fine since....now
Any advise welcome
ECU ok - car not starting
Many Thanks for your help today Tom!

This also may have been issue with the old ECU as it was only starting in limp mode and now looks to have gone to this stage. VCDS dump was taken.
Sound like an mechanical issue now. The only change was replace wiper motor (remove battery & ECU) and replace coolant temperature sensor.
Any other ideas apart from the obvious :
Battery (car been sat for 5 days voltage tested ok)
Fuel pump relay (previous error due to old ecu pin connection)
