Hello,

Im new to this group after being recommended so I hope you can help.

Basically I have an 'N' reg peugeot 306 and when I turn on the ignition
to accessory the engine diagnostics light flashes continuously when it
usually stays on until I start the car. As a consequence the car sounds
as rough as gravel when I try and start it. The immobiliser works fine
etc so the ecu cant be completely trollied!

As a side note, when I turn the ignition on usually there is a noise,
like an electric hum that usually last for about 2 seconds that no
longer happens, which I can only guess is directly linked to the
problem described above.

Somebody please help!!

Many thanks in advance
