Hi this my first post so here goes ,i have a Audi A4 avant [2010] i have had it for 3 years with no trouble but the alarm has started to go of when the car is parked ,it seams to be when the car is parked in the sun , i took it to a local garage to have the code read and it came up with 01403 glass break sensor rear ,has anyone had a similar problem and if so where is the sensor in the car and can it be replaced or turned off many thanks graham
