Hi all,
Much searching around later, I am not entirely clear on the following & would appreciate your input please.
Our 2011 A3 2.0 TDI 170 (with stop-start) has the original Moll 5K0 915 105 G battery. Now so far as I can tell, this is a conventional lead acid battery and not an AGM.
I think 2011 would have been one of the first, or at least definitely an early generation stop-start.
Firstly can anyone confirm this is a lead acid battery and not AGM?
Secondly, what have people replaced these with, in terms of have you gone for lead acid again or gone with an AGM?
Most of the battery lookup sites (I'll probably order from https://www.tayna.co.uk/) say the regulars lead acid batteries are not for start-stop cars, but as above I think that's what the A3 TDIs with early stat-stop were fitted with.
I have VCDS and can recode as necessary, but note coding only wants the Ah rating, manufacturer & serial number. There is nothing there that designates AGM or not.
To be fair it's lasted 9 years and we'll not likely still have it in another 9, so the same again wouldn't be a bad thing.
I have my CTEK connected doing a recondition at the moment, to see if that revives it. On that point, if the CTEK revives the battery, do you think it worth changing a digit in the serial number coding so the car thinks it is a new battery? I am not sure how advanced the BDM is on these.
thanks in advance
