I've told him to phone Stu and bother him with it, i'm getting a bit cheesed off with it now tbh. Its gone on for well over a year now and Regal ( who fitted the engine) dont want to know
Its also been into 4 (and I use the term loosely) specialist garages and I dont think any of them have checked the management or any of the sensors. Bloody Vauxhalls. Glad I've got a nice reliable Ford!
