Recoding after replacing a EPB battery with an AGM on? 2017 Tiguan 2.0 TSI162

Hi All,

I have just replaced the original factory fitted EFB battery with a Supercharge AGM battery that was supplied and fitted by a non-dealer VW mechanic. When I questioned whether the vehicle needed recoding with the battery details, the mechanic said no. I then spoke to his manager who confirmed that recoding is not required. I challenged him and referred to what I have read on these forums and he said he will check and get back to me. This doesn't sound right to me. Can anyone enlighten me?

Thanks!

Yes the gateway which monitors the battery needs to be told the battery chemistry and capacity as this feeds into the start/stop algorithm.
