Hi...
Can anyone help please.
I've got a 2006 vauxhall signum 3.0ltr deisel.
The exhuast emmission light has came up on the dash.
I've used EGR valve cleaner plus deisel injector cleaner in the tank. Ive taken the EGR valve apart and cleaned it up.
Still light stays on and engine in safe mode.
Has anyone any ideas please would be much appreciated.
Martin

Wild guessing won't get you very far. You need to use suitable diagnostic equipment firstly to see what fault code/s have been stored, and then do some live data checking. Your problem could be anything.
