a friend of mine took the comms 2000 unit off his 54plate 206 1.4 car to try and determine where the airbag fault was on another car, same year. The airbag light went out but nothing else worked and the car wouldn't start. so he put it's original one back on, everything ok other than the airbag fault which we have now cured.
He put his comms 2000 back on his own car but now now nothing works at all! just an immobilizer fault on the dash screen, no wipers, indicators or nothing. He's been told the unit is knacked and been trying to find another. So my question is, does the numbers on the unit have to be an EXACT match, we've found one that is ony the last two numbers different, would this do?
His number is 96595 076 XT
The one found is 96595 074 XT
Any help or advise would be most appreciated.
