Astra 1.9CDti 150
Engine managment light came on so i took it to a garage (non vauxhall) who told me that it was my EGR valve. They sugested a good clean out. So this i have done but the engine managment light is still on.
Does the fault code need to be deleted or would it simply just not come on if the problem had been fixed?
If i need to replace the EGR valve then im confident enough to do it myself but same question as above.. Will it need to be plugged in to delete the faut code?
