Just a little head scratcher that might help you all out there. I have an 07 Fabia Mk1 VRS SE. For the past six months I’ve had a problem with starting the car. Everything seemed normal, no warning lights etc, it would just randomly decide not to start hot or cold. I started carrying both keys (which both worked normally) and doing the key reset procedure, not that it worked reliably to get the car going, just couldn’t put my finger on the cause. Neither could a couple of local garages I tried. Took my daughter to school today, came back to the car and nothing, plenty of battery, all the lights did what they should but nothing at the point of turning the key. AA patrol came, used his laptop to show me all the electrics are working as they should. So he went back to basics. Bashed the starter motor and hey presto it worked. I just need a new one. Hope this might stop some of you going down the immobiliser / electrics / what the hell is it route. Always check the basics. Digging out my Haynes manual now.
