Hi. Would very much appreciate guide lines on how to change the Battery from a standard to a AGM Type as I have retro fitted a Remote Start and Timed Auxiliary Fuel Burner. I understand I have to code via VCDS the new battery specs, but as I planning on purchasing a Varta Silver Dynamic AGM 595 901 085 (95Ah/850CCA) direct from a local supplier it will not have the relavent VAG Part number and serial numbers. Does anybody have these to hand or will VCDS except Varta numbers? Again much appreciated any help as I have dead cold car!!
