    Strange issue here. My Corsa has started to intermittently rev to 1500k, my throttle will do nothing to change this. It lacks any sort of effect on it.

    Hi Vauxhall loving folkses. My garage tells me my cooling fan will not cut in when the engine gets too hot. They say they did tests, and I need a "Cooling System Module".

    Hi. My Cavalier has a fault with the ABS. I read the flash code from it and it's reporting a fault with the ECU. I was having a look around this forum about how to replace the ECU.

    Hello Long story but… I have 2.0 2008 Vivaro, and one day it just didnt start. I had a mobile electrician come out to have a look and he narrowed it down to an ECU fault. The ECU wasnt sending an earth down to a relay and for some reason the van didnt start. He managed to fix the issue by...
