Hi all, I have been slowly fixing my A3 2.0Tdi, had the Mechatronics unit removed and checked and new Atf oil. A few days later after coming back from the garage the airbag warning light started to flash on and off. After using my mates vag com, i have the following code: Address 15: Airbags Labels: 8P0-959-655-84.lbl Part No SW: 8P0 959 655 D HW: 8P0 959 655 D Component: Airbag 8.4ED H00 0140 Coding: 0011602 Shop #: WSC 06435 000 00000 VCID: 438ECAFA7BFD 1 Fault Found: 01739 - Crash Sensor for Front Airbag; Pass. Side (G284) 012 - Electrical Fault in Circuit - MIL ON Where is the pass crash sensor located in the car ? Also i have a slight ticking noise when in idle and park, but i goes away when in drive or if the revs are raised slightly. Any ideas on this noise would be appreciated.
