So would my steps be
- Disconnect the high voltage
- Disconnect (bigger) Main battery (mines on the left looking in from the boot/trunk)
- do the change over
- connect Main battery terminals (is it negative first, then positive?)
- reconnect high voltage green plug
- Do the ISTA 'new battery procedure'
I'm actually changing from 90a to 95a battery G14 019 Varta AGM. Do I need to do anything different in ISTA to tell it it's now 95 instead of 90a? |
Hi Andy_Kay, I have the similar issue. Did you end up calibrating the steering wheel while replacing the batteries? I need to replace 12v battery and the AUX (AGM) battery. I'm fine with all the procedures except steering wheel part.
