Well, not really my idea of a first post, but well
....these things happen.
Been driving our 528i around town today, parked it outside a cafe, had a coffee and then went to start it up again....
Engine cranked over, gave a puff off smoke out from the front (under the bonnet) and then stalled. Whenever you try to turn the engine over now, simply stalls and dies.
If you put yr foot on the gas, it will rev up but as soon as you let go it stalls. Engine seems to be running a bit rich as well and sounds to be slightly missfiring.
The car has done about 190,000kms, but has been regularly serviced by our local BMW dealer.
Any ideas? Head gasket gone? Sensor died? Major or minor?
