Hi guys!

Sorry for such a basic question but I need to do some electric adjustments and need to disconnects and maybe take the whole battery out.

The question is will I have any problems with the ECU? Because I have the radio code but I don't have the "key code".

Also I haven't had any fault codes or any problem with my electrical system whatsoever, could that be affected by the battery disconnection?

Thank you very much!

you wont need a key code it should be fine
