VW damaged my car during service!

[clubber24_7]

Hi all- want some advice

Dropped my vw off at dealership (1.4 tdi sel 15 plate) for its 20k service and an oil change.

All was done and paid up, turned the key...

Numerous error messages came up- rear parking sensor continual bleep and error message after error message (esc, automatic headlights, tyre pressure) obviously not happy

Didn't drive it anywhere, they've given me a courtesy car but called me up saying they're baffled- they've had to send a error code report off to Germany to get ideas, and can't understand why it's happened. I definitely had no probs with the car at all, and they're saying it was all 'mechanical work' they've done, and they didn't touch the electrics.

I've got no idea how long this is going to take, and just wanted to ask 2 questions for you knowledgable people- after spending £280!

1) what do you think they've done to my car...
2) should I be asking for some refund/ compensation, and if so, what should I be asking for?

Thanks in advance!

I might be being to simplistic here but have they had ignition, lights etc on during the service and run the battery down, that can throw up all sorts of errors. I'v e seen this a few times on family / friends cars where the engine will either crank over and not start or start but with errors / warnings and a new battery or battery charge has cleared it up.
