Hi all, i've got an issue with my engine cutting out. Pull up to the lights and it dies, it will restart but turns over for a while before it does. Seems to only start doing it on a run, on the motorway the other day I had cruise control on and although it kept at the selected speed i could fell it trying to die, left the motorway slowed down to stop, cut out. Scanned it - p1427 and p3000 returned - mechanic friend thinks the swirl flaps might have been removed hence the first code the second seems to relate to a fuel rail sensor. Cleared the codes and went for a short drive today no codes returned as yet . . .

the car is an E91 2006 320d Msport any thoughts?

Update: issue returned, idle "hunting" go to pull away engine dies.

scanned, P1427 and P3000 again. Not sure when it was changed last so i've ordered a fuel filter as a first step. Is it worth replacing the sensor at this point?
Any other guidance gratefully received

Monitoring deviation test, rail pressure sensor. The fault is detected if the non-linearised value of the rail pressure (voltage) upon engine start or during after-run of the control unit exceeds the limit value (excessive positive offset).

Engine start limit value: 648 mV

After-run limit value: 648 mV

Condition for fault identification: Monitoring takes place continuously if no electrical faults are set.

Control unit voltage: 9.5 V to 16 V.
Condition for fault memory entry At start: 30 ms

During control unit after-run: 100 ms

Action in service
1. Check line and plug connections

- Check connections for corrosion!

- Check connectors for correct locking!

2. Carry out function check.

If checks mentioned above are OK: Replace rail pressure sensor.
