- Disconnect Main battery (right)
Do the job required - Android...
- Reconnect Main
- Reconnect Aux
- Reconnect High Voltage
- Reset Sunroof, clock
- Reset steering with cable and ISTA-D (which I never did so far).
Are these the correct steps ? |
Just about to change my big (main) battery as I think it's got an issue not holding charge.
Do I need to disconnect the smaller 'Aux' battery first? I notice these steps were to change some audio thingy, but I'm just doing a swap of Main (bigger) battery.
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?
