HI guys
after finding my diagnostic port i was able to read the fault code that is causing the engine light to come on.
p0405 - exhaust gas recirculation sensor "a" circuit low
can anyone suggest how to approch this?
Vauxhall last scanned the car and said that it was an o2 sensor (of the 4 i have replaced 2 recently) but this error code seems to suggest something else?
any ideas?
thanks.
