Quick question bro the one currently in my car is 68AH this one is 72AH will that make a difference ? More so will it be ok and run properly without issue as it’s more powerful ?
Makes no difference at all. It's not really more powerful. The CCA (Cold Cranking Amps) is how much power it puts through the starter motor. For a TDI, the higher the better. My current battery is 70AH with 760CCA. ?
 
Ok thanks pal. I will let u know if I struggle with the coding. Going to change them over now.
