Can VAG be used to check the bonnet sensor on the S3 (2002 BAM)? My alarm isn't arming and I think i've narrowed the problem down to the bonnet sensor as the DIS shows both doors and the boot working. I took the sensor apart yesterday and gave it a squirt of WD40 to try and clean it up at bit but it still doesn't work. I need to determine whether the sensor is actually broken or if VAG has been used to disable the alarm. If anyone can confirm for me.
