Well, the Veccy has gone. With all the trouble I had on my 06 plate CDTI 150, I couldn't stand it anymore. Purchased in January last year, it has had swirl flaps, alternators, EGR valves, dodgy electrics, dodgy stereo...Vauxhall to be fair rectified the faults (apart from the stereo and dodgy electrics as no fault found..) but I didn't expect so much trouble on such a new car.
Traded it in and bought an 05 Volvo S60 2.0T Sport. Slightly higher mileage and age, but 1 previous owner and Volvo reliability means hopefully less trouble this time round!
I'd just like to thank the Vectra C community for their help with the Vectra over the last year and hope you all have less trouble than I did!
