 light went out and all was ok, then it kept happening for about  10 miles i stopped  for 15 mins
then every thing was ok for the next 80 miles (playing with bmw) then got onto the mway then it started
again, went out this morning and now its still there, any ideas.

Do the paperclip test & let us know the fault codes.

145   Incorrect immobiliser signal received Faulty unit or break in wiring
93 Hall Effect Switch (HES) Low voltage
73 Air Flow Sensor (AFS) Low voltage
72 Throttle Switch (TS) - full load contact High voltage - Full load switch not running
31 Engine RPM signal (crankshaft sensor) No signal  but this could be if your engine was not running during the paper clip test

The hall sensor is the cam sensor.  I would look at sorting this first. MAF tends to come up erroneously...

MAF is aka Air flow sensor - TB is right and Vx often recommend a change before looking for the fault.  It mixes air to match fuel but if another sensor is out it gets confused so check and clear other fault codes first.

Cam sensor is on the exhaust cam of the passenger side bank, just behind the cam belt cover.

145 is immobiliser, and will most likely be an old code. Immboliser codes do not appear to disappear from ECU unless cleared...

Thanks pete

IIRC, yours is a 96 model, so Tech1/Tech2 or cheapo Tech2 lead (should work, even though its 97 on, as same ECU as later)
