    i think you want at least 60 amp. Ours is stupidly small too, although its correct according to the book, and it really struggles in cold weather even though its not even a year old.

    The old car had a huge battery from a TDI, which started the motor without any problems

    Order a battery for a 2.5TDI and it should be plenty big enough!

    Something like this will probably do it:

    Mines standard too and struggles for the first turnover. Im about to get a 80amp one, but you really want to be looking at the CCA rating for cold cranking.
