Vauxhall Astra astra 2016 k alarm sounds off, indicators not working + autobox interior indicator not illuminated.

Car: Vauxhall Astra
Variant: 1.4 (k) sri petrol automatic estate
Model Year: 2016
Categories: Electrics, ECU, Warnings & Lights
Astra 2016 k alarm sounded off this afternoon when I turned the key to obtain access to the vehicle. The exterior indicator lights did not work whilst the alarm was sounding off. The alarm sounded off for about 20 seconds then stopped, then sounded again (whilst the car drove normally). This repeated about five times then stopped altogether. The car thencontinued to drive normally but without the interior selector lever indicator (P,R,N,D) being illuminted. The car is not yet five years old, done just over 15,000 (backed by MOT evidence) and has been trouble free in the six months I have owned it. Has anyone experienced the symptons detailed above. Thanks for getting this far.

Faults like that can be triggered by a low battery condition . You could check your battery voltage and charge if needed . If car not used a lot and for short trips it can cause battery to get a bit low .

Hi, just got my car back after garage found two Body Control Module faults:
u1529/u152d LIN Bus 2 Lost Communication with device device 0/device 13.
Then the garage checked the battery and re-booted the system and they charged me an hours labour. It looks like you were right and the low battery condition made the items above crash. Thanks Stephen
