Hi all, just been on the phone to the audi dealer and he is saying that the battery which has been put in my car by my local garage is incorrect. Currently I have a Bosch S5 battery 110Ah 920A CCA. Now the dealer is saying that the battery should be 520A CCA. He quoted me the OEN which is 000915105DL. Now when I've done a search for the OEN battery funnily enough my Bosch S5 920A CCA comes up as a comparable match?? So my question is...Is the dearer incorrect in saying my 920A CCA battery is wrong or is the website wrong which says it is suitable?
