Having trawled around the subject I have yet to find an answer to this so I thought I'd start my own thread and be as precise as I can with my symptoms to see any of you good people can point me in the right direction.
About once a week I get the MCSF warning light on. I can tell when it's going to happen now because for some reason, instead of the engine springing into life instantly when I turn the key, I find that I have to stop after 2 or 3 seconds and have a second go because it hasn't started. On the second occasion it starts instantly but the MCSF light comes on. This remains on for around 6-10 starts but then clears itself only to return again around a week later, usually just as I start to hope it's gone for good!
Whilst the warning light is on (or off for that matter) it appears to have absolutely no effect on the cars performance, which I would think rules out the usual MAF problem that is so often suggested here. I have described the symptoms to my local indie and they think that Alfa Diag is unlikely to pinpoint the problem. They are in the process of getting a Snap On diagnosis tool that they reckon will give more detail. So my choices are, wait for a couple of weeks and let them try to diagnose with that, go to the local stealer and pay for a full Alfa diagnosis, or finally, see if I can self diagnose with your help.
So, could anyone suggest anything else that it could be detecting?
Is it possible the fault no longer exists and it is just stored on the ecu and needs clearing?
What checks are done that can result in a MCSF warning?
For info I have just fitted a new battery because initially I thought that was the problem
I really can't face replacing parts on a process of elimination
Any help would be very gratefully received
