hi all, wonder if you can help.

During a recent mobile phone bluetooth handsfree kit installation the phone engineer managed to disable my windscreen and headlight washer motors, albeit the windscreen wipers still worked. I don't know what he did, but he managed to get the windscreen washer motors running, but not the pop up headlight washers. Any ideas what/where I should check?

It may also be worth noting that a few months ago Audi changed the cam belt on my A4 3.0 quattro sport, and to be honest, I'm not certain if the headlight washers have been working since then. Given my experience of Bristol Audi, it wouldn't surprise me if they have forgoten to connect something when putting the front of the car back together. Once again, has anyone an idea where I should look for anything they may have done?

Thanks for reading my post andany help that you can offer.
