b5 or b6 model? probably have more luck posting in model forum rather than diesel forum, but i would check for water in battery compartment as drainage holes can get blocked and it can flood into passenger compartment and get into conveniance modules located under carpet, or on earlier b5 models check central locking pump in boot for water damage as hazards and lights are linked through that
just had car valleted so that sounds very likely,thanks very much also how and whats the differance b5 and b6

I had similar issue, on C5 A6, passenger footwell under carpet was soaking, this is where ECU is and was effecting locking and lights etc, was leaking from poor windscreen scuttle seal leaking in to pollen filter intake and in to foot well.
will this dry out over time and work properly or will i have to reolace or repair something and its a b6 model

Blow ma own trumpet?
Look for a puddle of water around the battery compartment. There's a drain hole in there and behind the brake servo. Make sure these are clear otherwise you will have probelms..

You will need to take the seat out and some trim and raise the carpet to soak up any water as the inner and outer carpet is sealed by a membrane so it will not evaporate, nither water spillage inside can drain through.
It's surprising how much water it will absorb!
good news it seems to have fixed its self happy days
