Astra SXI - Need help with engine warning light - AJSXI

Hi all,

I need some help I have an engine warning light on my car everytime it comes up its saying spark plugs and or coil pack need replacing,

Have had both items mentioned changed at Vauxhaul dealership but the dreaded light is back on. Now im sick of dealing with Vauxhall i would like to know if there is any other areas i can look at before i bite the bullet and change the ECU :(

Almost certainly not the ECU.. If it was your car would stop running.

Sounds like a snesor or a bad wiring connection...

What year and engine code, what diagnostic code(s) are you getting?

Astra SXI - Need help with engine warning light - AJSXI

its a 53 plate astra g

the codes according to the Vaxhaull garage are spark plugs or coil pack,

over the past two years the car has had, spak plugs, coil pack and O2 sensor,

and in the past few months it has had spark plugs and on Thursday a new Coil pack. Friday night lamp back on.

I even took reciepts in to show garage and said i doubted that the coil pack would be the fault, they said if it was not a genuine vauxhall part then it would cause conflicts and used that to convince me it may be the fault.

have just ordered the software and lead to diognose my own faults because so far i have thrown £400 down the drain to try solve this problem.

You didn't happen to notice a large telescope in that garage did you? It's just that seem to have seen you coming from a mile off......:-(

I take it that you've ordered OP-COM and a lead? I doubt it will tell you more than others have as regards fault codes, although at least you won't be paying for the privilege(!) Hooking it up in logging mode and then driving around for a bit may shed some light.
