Flatout

An update.... Things took a turn for the worse, the car failed to start in hot weather. In desperation I booked in with Audi. They could not fault the car. So I recently put lines in either side of the start relays (there are two) Each time I started the car I had a volt meter checking the voltage. It appeared there was a voltage to the line out to the starter motor even when it failed to crank. I tried to put a line in at the starter motor, but short of cutting the cable there was no easy way of putting a cable in. So I decided it must be the solenoid on the Starter motor I have since had it replaced.

Because of the access, I ended up paying Audi to do it. It was a lot, but IF it fixes it it will be money well spent

I'll update as days go by.
