Hi All, My battery suddenly lost charge and I think it is time to replace it. Last time I changed it was in 2013. Originally there was a 100AH battery which I replaced with a 110AH battery.
I am now looking for batteries online with my Reg and the results are all between 44AH and 85AH.

I will probably be selling my car this year and not really looking to spend a lot of money. If it doesn't really need a 100AH+ battery, I would like to go with something smaller. Can you please let me know what is required for a Audi A6 C6 2.0 TDI?__PRESENT__PRESENT
