Driving down from Scotland ten days ago, exhaust emissions light came on (steady). Drove the last 90 miles home at 50-60 mph, car was running OK.
Called the Vauxhall dealers the next day hoping to check it in for a diagnostic test. There was going to be several days delay, but the guy asked if I had just filled with petrol before the light came on - I had. He suggested that it may clear after a few stops and starts as the ecu adjusted itself to this particular load of petrol. Sounded feasible although I had noticed that the revs on a cold start had been a bit higher than normal (2,000 rather than 1500) for a few days before the light came on.
In the next few days it ran increasingly rough when cold, sometimes not responding to the throttle at all for a minute or so until warm. Once warm it ran smoothly enough, but power seemed down.
Car went into dealers yesterday for diagnostic check & fix - they replaced the Mass Air Flow Sensor & road tested the car and reckoned it performed OK and the emissions light was out. When I picked it up, it started and ran OK, without the increased revs when cold. The emissions light was out and the power seemed back to normal. But today when my wife was driving it the light came back on again and it was running rough when starting from cold. Tonight I tried to start it but it was dead. It unlocked OK, and the ignition lights came on, but when I tried to start it all the lights and the info panel went out, there were a few fairly soft clicks and whirrs and then nothing. Tried a few times without success. Lights seemed bright enough, so didn't *seem* like a flat battery. Then tried to lock the car using the remote and it wouldn't lock, so I locked it manually.
I need to get it going to take it to the dealers to fix it (they won't touch anything off their premises. Any ideas to get it going (I'll try a jump start tomorrow as a first stab)?
Thanks Biggles
