Replacement battery?

Hi guys,looks like i need to replace mine after 5 years! I know you have to recode the ecu through vagcom and put the serial number in of the new battery from Audi so it knows it has a new battery. Has anybody put in a much cheaper generic battery before without any issues?
Cheers

I used an AGM battery from Advanced battery supplies.

Not had any issues.

You don't need an AGM battery unless you have stop/start.

There are no OEM spec batteries available in the aftermarket.  The OEM is 110Ah

I paid £140 from TPS for OEM part number 000 915 105 DL

RRP is £194

At £140 it's only about £20 more than a wrong spec battery from Halfords etc.

Removal is a bit involved (more so if you have B&O) but doable.  You have to disconnect a plug on the +ve terminal to reset battery management and then use VCDS to code the new one

lovely thanks so i can use that part number for my S5 then?

Yep, mine's an S5 Sportback and the battery is identical for S4/S5

If you go in to TPS they'll confirm based on registration number and you should be able to use that price I've quoted to get a similar discount (27.5%)

If you have, or can borrow, a high quality battery charger I would give it a charge before fitting as they can be sat around for quite a long time.
