hey i took out the factory radio and mfd screen from my astra, so i could set up a comp.
i didnt get that far though as after a week with no radio, 7 ecn codes appeared and the battery went dead AND wont hold a charge.
the dealership maintain i damaged the ecu and want me to pay to fix it. i had 2 codes before i took out the radio which the dealership claimed to fix.
can the removal of the radio really do that much damage or is he talking out his arse?
