Need some help! For the last few months my car has not started on several occasions due to a low battery. It was in for a service last month and I asked for a check to be done on the battery and was told it was OK although they said if it continued to happen it would be a new battery that I needed. Has anyone else experienced this with a 5 year old car? I would have expected another year or two yet! Got a price from my VW dealer…£245! Seems I will just have to get a battery but thought I’d ask here for reassurance.

Does your stop/start still work as normal? If not, that's a sure sign the battery is on its way out. If it's the original battery then you've done well to get this long out of it. Mine went after 3.5 years.

I'm well over seven years on the original battery but it's not unusual to have to replace them after 5 years, it's luck of the draw.

If you do have to replace it you can get a decent AGM battery for at least a hundred quid cheaper than the dealer. Only thing is it will need to be coded which only a garage can do if you haven't got an OBD tool.

I haven't really noticed if it works as normal or not, but I do know it has stop/started on the odd occasion - maybe not as much as it should normally do.

Yea, seems I got the short straw this time! I assume a VW battery is straight forward plug and play - no coding required? I will just fit it myself.

Another reason to make turning off stop / start part of the engine start process.

It needs coding...

It needs coding because the ecu remembers the characteristics of the old battery and the alternator charges accordingly so needs to be reset.

Any recommendations for the best app to use with OBDII to allow programming?
