Hi,
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

Hello,
Im sure ive come accross this or something like it before,
The person then didnt want to spend any money...
Im guessing its a throttle cable model not a drive by wire?
I have VAG COM and can read the codes for you but i dont know of any procedures to clear or reset the issue off the top of my head,
 
it needs to go on vcds for a TBA

and if that wont work then a new throtlebody
 
Thanks

I think it is Drive by wire.

Maybe first get it just cleaned up and then Aligned...

Failed Throttle BodyAlignment causes:
Dirty throttle Body
Low system voltage(check battery)
Cable Adjustment Issue
Wiring Harness issue
Faulty Throttle Body
Faulty ECM
Outsideinfluence...check 02 sensors
 
If its the drive by wire ( same as my 2001 S3) i can have a look for you.
Drop me a PM to discuss?

That will be great! yes its drive by wire

Did have a look at VCDS-light with the Gendan cable...but now depends if the B5 is finally nearing its end :]
 
Yes vcds will adapt the new ecu. I would be inclines to try tba first though unless there is signs of damage through corrosion etc on ecu.

Happy to help out with vcds, thanks tom

Many Thanks for your help today Tom!

*update*
Good news : Ecu replaced and TBA ok. No error codes

Bad news : Car not starting - no error codes on VCDS

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)

Starter motor
fuel pump
Fuel pump relay (previous error due to old ecu pin connection)
 
so the car is still not starting ?

are you geting fuel ?
 
Ecu plugged had suffered heavy water damage, I wouldnt know where to begin with testing the wiring for shorts further up the loom.
Old ecu would not allow the throttle body alignment. Assume drivers damaged due to water damage.
New ecu adapted, TBA completed, no error codes stored with VCDS.
Battery voltage good, spark good.

If the engine is flooded it would start today. Another way to start a flooded engine is remove all leads and push them on so they only just touch the plugs but dont clip on them. (not sure why this works).

Also try removing cam belt cover to check cams turn when cranking.

I suspect there is another damaged sensor/actuator caused by the water.

Im sorry I dont know enough about petrol engine management to help you further :(

Here are the extracts from the initial VCDS log, all codes were cleared, even after failing to start, but as i said, somethine may come back when it starts, feel free to pop round on the way to work.

are they any relays in the ecu box as if they got wet they can stop starting
im not up on the B5 really
 
I didnt notice anything in the ecu box, but thinking about it i didnt see the gromet to the bulkhead either, maybe water got down to the relay rack under the driver side dash?
 
Many thanks chaps!

This was the issue a year ago. Sorted after the pin cleanup.Audi A4 B5 starting problems Changing the wiper motor may have not only disturbed an old issue but introduced some new ones.Also replaced at the time was coolant temperature sensor.

The car would start but rev was low. Would drive in limp mode. TB Codes would not clear.After sitting for a few days the car would not start or rev.


After trying to start a few times...the oil light does come up sometimes...

Will have a look at the battery and relays under the driver dash. Check the obvious and the over to the Auto expert.

Steady as she goes...nowhere....all things end at some point :)

All sorted and been running fine for a few day!

Ecu harness female connector rewired. One wire housing connector had corrosion and was replaced with a used one. TBA came to life and engine started to cough but did not start. Was all gassed up and re jumped to start it up.

Learning experience is make sure your connectors look ok. Looking for a good way to check Continuity on each wire from harness to the socket. A loose connection will just throw up a bunch of codes or nothing at all...
