Sorry I was incorrect saying it’s telling me the car wasn’t locked! The car was locked but the alarm wasn’t on! Which I was grateful for because I started hearing the alarm in my sleep, paranoia had set in!
I thought it would stop , without having a mechanic to intervene, but no. As soon as it starts randomly going off, get it booked in to have the alarm sensor changed, but be prepared for a big bill.
I had booked in the car initially with Audi and they had informed me “to investigate” aka hook up to the computer it would £150 before they even find out what is wrong!
Hope this helps someone else. I tried everything prior to getting properly sorted ie, changed batteries in both key hobs, used nearly a full canister of fly spray in case a fly was setting off and even not locking the car.
Thanks
Gillian
