Had AA out becuase it wouldnt start, he checked the alt and nothing so had a 2nd one in and lasted a day, took it back and he checked it and it only output 12.5v, so he got another slightly diff one but it still gave out 12.5v, he says it strange that two would do this. Then he informed me that on this model the wire from the alternator goes into the ecu and its the ecu that regulates the voltage from the alt and it could be the ecu that has a problem. He is currently fitting a brand new one as i found on a veccy forum that it has to be canbus approved otherwise it wont work. Does anyone have any experionce with this as i am desperate.
