I own a Mk6 TDi 1.6l 2011. Just to build up a backstory, i have recently just taken it in for a timing belt and water pump change. After getting the car back my parking sensors don't activate at all, the assisted steering function doesn't work and my key or spare wouldn't lock the car using the remote locking.
I noticed as i put light pressure anywhere near the key ignition, while the key was in and car running, the parking sensor light flickered but still the parking sensors did nothing. This says to me that its a earthing problem but do any of the earths even get disturbed during a timing belt change?
Please any help is welcome, Thanks.
