HELP!! sorry just at my wit's end here. I've got a 2001 Renault Megane auto with 60k on the clock. Its actually a very good car, clean engine, runs really well, etc, etc. BUT and its a big but. Since I got it a year ago I've had intermittent starting problems with it. Last winter and this winter.

Dashboard lights up as you turn the ignition, then when you try to start it nothing. No click, engine doesn't turn over, lights go out but as soon as you release the key they go back on again.

I've had the RAC and garage go over the car on so many occassions. On their advice I've had a new battery, had the antifreeze changed, the coils have been replaced, all the connections and wiring has been checked. Then both RAC and garage decided it was the interuptor switch (the switch that stops an automatic starting in gear) I've had that replaced. (Its also serviced regularly and flew through its MOT)

But its still doing it. I can often get it going by pushing the gear shift right through the range quite roughly and back to P or N. If that doesn't work then I'll leave it for five minutes and it starts. If that doesn't work I spray the starter motor area with WD40 and it starts or does after five minutes. If that doesn't work OH has a poke around and normally gets it going eventually.

Has anyone got any ideas before I throw away yet more money on it?
