Alarm wont stop going off

Post by jezzasin » Wed Apr 19, 2017 9:36 pm

Evening guys since i got my passat tdi the alarm has been very temperamental, always locked and unlocked the door and windows, but now the battery is back on after a year it wont stop going off, im not sure if the alarm is factory fitted or something that was put in by vw after as it looks like a £35 cheapy off ebay





Im wondering if anyone has seen this type before and could i trace all the wiring and remove it easily or does it need vagcom to code it out before hand

I do not know much at all about alarms, but the part number, 998VAG153 suggests that it is indeed an aftermarket device, - the VAG in the part number indicates that it was procured locally and supplied by VAG (UK).

Google that part number for more information.


You can also Google:

Hope that helps a bit.
