Please help. Need to alarm my car.
I had my car remapped and returned working fine. After a couple days the alarm started going off after locking. I tried locking it again to disengage motion sensor and it made no difference.
Went back later in the evening. Opened and closed all doors, bonnet, boot and it worked fine.
Drove off next day. Locked the car and it started going off (without the indicators going off) just the loud chirp from near back left wheel.
I then tried to tape down the sensor. No effect. I then disconnected the sensor completely. No effect. I changed the bonnet sensor swith. No effect. Mechanic wants £100 to diagnose?
What could it be???
