    Hi, I'm having a problem with my 2011 vivaro campervan, 1995 cc engine. Got the van a couple of years ago, drove nicely except sometimes when going above 70mph "check injection" sign would appear and it'd loose some power, but still drivable. As it was rarely driven at high speeds that was not...

    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. The weird thing is that when I press the brake pedal it brings the revs back to zero. There does not seem to be an water pooling in the Window...

    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". They also called it a "ECU" so I am confused already, as I am no mechanic. I haven't much money;and they said it would be be...

    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.

    Hi guys wondering if anyone can shed some light on a problem of mine. The mother in law's mk4 astra 1.4 16v Needs an ECU the fault only presents itself when the engine is warm and all codes disappear whenever the engine is cold. This is pointing to the ecu. Question is can different ECU codes...

    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...
