Ok thanks - that sounds about right then - all the prices are for fitting - although it's not a price from Audi, but a specialist in German cars.

I'm not terribly good at botching thins up or diy repairs, so may opt for the replacement - just wanted to make sure that it would cure the problem really!

They said the fault on the doors was just to do with the dead locking, so as long as that is not the fault with the alarm, i will put up with that. (I have a similar problem with the A/C not working - quoted £600 to replace the compressor (I think) - gonna just open the windows! )

The engine is a 1.9TDi (130) - apparently the front of the car had to be removed!

Anyway, thanks for help so far.
