Hi All

 

I did a scan on the VRS today and there were several faults flagged up including Alarm Horn, ABS, Airbag low voltage etc.

 

Lots of RED so quite worrying.

 

I cleared the codes and scanned again. Only one fault is still there at the moment for the alarm horn. How do I fix it??

ross-techs wiki page is a perfect place to find info on fault codes. The one you have listed can he found here I would suggest that the internal battery is at fault in the alarm siren and you need a new unit. These normally have a service life of around 6 years so if yours is original it will be over due!!

Thanks mate. That is very helpful.

 

For anyone looking to swap out the battery themselves, here's a link for the Varta internal battery:
