I’m new to the forum, had the Vectra since last July.
I have a Vectra 04 SRI 1.9 CDTI 150, recently been having some issues with it ever since I got it, the latest ones are below.
Diagnostic machine suggests three codes which I have searched on here and Google but nobody continues thier thread to say whether they have corrected the fault or what they have done.
I have the following codes on my car:
P0621 – Generator lamp control circuit malfunction
P0070 – Ambient air temperature sensor
The codes were cleared but they keep coming back.
The car’s idle is very rough and a car with a spanner keeps flashing on the dash intermittently. It also seems to throwing out some smoke on start up. The boost sensor has been cleaned and also the turbo pipes.
Any help would be appreciated, thanks in advance.
