Battery low voltage

[Watts]

I can get a new battery from Halfords but wondering will they code it? The guys at VW said you don't need to do this but tbh not sure I trust them!

The following from Halfords website - Halfords Start/Stop batteries in some vehicles require the battery to be registered with the on-board computer system, so we strongly recommend professional fitting.

It needs doing so perhaps call the branch in advance and check.

Thanks mate, will call them. VW wanted £360 for a new one, maybe see how it is over the weekend and try a garage that I normally use.

I changed my battery a couple of years ago as the Banner EFB was dying and my dashcam (parking mode) was putting too much strain on it.

Swapped it out for a Bosch AGM Type 096 S5A08 from Tanya Batteries. You can code via OBD11, basically you just need to 'tell' the car it has a new battery. If you have OBD11/VCDS its pretty easy.

Got my replacement battery supplied and fitted into my GTD back in 2021. They coded it too.

Almost 5 years down the line and no issues.

I've just gone down a similar route, and ordered an Exide battery from Tayna. 760 CCAs I think it is, EFB.

After 2 weeks on charge over Xmas, the one on the car, wouldn't go above 12.3v.

Even though, car is driving fine with no issues, I now consider the battery to be failing.

So, once the new one arrives, I'll swap it out and get OBD11 to register it.

Will be doing DSG fluid at the same time, so it's got to come out anyway.
