This is old and probably no use to the OP, but I haven't seen it mentioned in the cinq section yet, so it may prove useful too some people.
If you replace the crank sensor or mess with it or the crank pulley, you should teach the ecu the new sensor and settings. This is called phonic wheel learn.
This is necessary as the sensor is inductive and measures a changed of magnetism cause by the crank ring turning, and is very sensitive.
To perform it, make sure the gap is ok, 0.8mm -> 1.5mm from the top of the notch to the face of the sensor.
Rest the ECU by disconnecting for 15 mins. Start it and let it get to temperature by idling (wait for the fan), then rev hard (above 5000rpm) and lift off immediately until it idles again. Do this 3 times and turn of the engine.
Job done.

I think first you let the cooling fan kick in twice, at least thats what had to be done to reset the phonic wheel on the Multipla.Idle up to operating temperature
5000 Rpm and lift off
Idle
5000 Rpm and lift off
Idle
5000 Rpm and lift off
Idle
Turn ignition off
Restart engine flashing light should now be cleared
hi thanks i'm just checking been told by someone else on here that you have to hold the revs over 5000 for 3 seconds is this right or do you just lift off after 5000
just had a diagnostic done on my sei mpi to see what the flashing ecu light was about and it came up phonic wheel manual reset required can anyone ex plain what phonic wheel is about and how to do a manual reset
