I have just been told (today) that the ECU on my 2003 v6 Signum is Kaput and is going to cost( including the diagnostic)in the region of £956.00.
It is overheating and causing the car to refuse to start after a short journey. This info comes from Smiths Vauxhall at Ilkeston.
Can anyone advise me,please,it would be much appreciated.
