Starter issues .. audi s2 avant .. ABY

When i hot wire the starter , the car starts. But on the key ignition it will not. How can i check it to find the issue on the easiest way ?

The cable is T1. And to check that its ok you should e relay ,, but what relay is it ? Cant find info on the starter relay.

Best Regards

Maybe the ignition switch has failed on the back of the barrel I had this

Hmm how do i find what wire it is in the back of the barrel ? So i can measure on the barrel if its working correct .. when turn the key to tve end then it should send a signal .. correct ? But it ia easier to check the relay first ..

Look at the circuit diagram, it will tell you the wire colour.
Circuit diagrams are on S2 Central.

Just a thought, you haven’t got an old alarm / immobiliser system on the car have you? If so I would remove this first and repair the wiring loom where it’s been cut.

I disconnected the switch from the back of the ignition then used a screwdriver to put into the slot and start the car I'm still using this method now as I can't change the barrel over yet

I have tried to look at the circuit diagram but no luck ... no immobilizer .. ok .. but if works with a srewdriver then it means the keyholder is broken ?

Yes there is a small piece of metal at the back of the barrel that slots into the starter switch mine had broken off

Don't they have a diode inside the ignition barrel? I think I read it age's ago on here

i removed the connector on the end of the barrel ,, but how do i remove the barrel it self ????

You have to accurately measure to a certain spot and drill a small hole. This allows you to release a small pin which retains the barrel. I had to do it on my car years ago. It's not difficult.

There are 2 small flat screws that you remove after the dashboard has benn removed, dont take them out all the way. ,, you have to scratch of the paint. I screw on each side. What does the numbers mean ,, what is for what ? It does rotate with a screw driver but will not start. Is there a relay for the starter ?
