Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi... Was driving to work the other day and the battery light started to come on and off... Along with the abs light. Once stopped it would not start. Jump started it to get home. Had the same symptoms on the drive back, but then the battery/abs light stopped coming on but the airbag light came on instead... The battery is around 1.5 years old. Now I am no expert, but is there a chance this could be that the belt needs replacing or is it more likely that the alternator is dodgy (or even battery??) eg if the belt is worn would it display these symptoms or does it either work or not work ( eg if it breaks??) Thanks in advance for any advice!!

POST 2Original post

First, have battery checked & charged. Sounds like alternator. If no belt, it would have over heated in minutes. The alternator can be rebuilt but mine made a loud spinning noise so I'd swap it out.

POST 3Original post

Check the ground connection.

POST 4Original post

Could also be the alternator regulator. Check the voltage with engine running / not running with a multi meter at the starter battery. With engine running it should be 13,8 volts. Else something is wrong. Regards Markus

POST 5 / ORIGINAL POSTEROriginal post

Cheers guys, may get some time midweek to check all this out and will update with any findings. Thanks for you time!

POST 6Original post

How much do you drive it? Do you keep it on a trickle charger when it sits? These cars can easily go through a battery in 1.5 years if not kept charged up. I'd do as Tim said and first get it load tested.

POST 7 / ORIGINAL POSTEROriginal post

Probably driven 3 or 4 days a week to and from work. Cool, will get battery checked too, thanks. And not kept on trickle but I bought one today so sounds like a good idea 👍

POST 8 / ORIGINAL POSTEROriginal post

Yep looks like alternator. Trickle charged battery. Then put meter on, read 12.5. Engine running.... Read 12.2
