"Check Engine" Warning over bumps
Getting a "Check Engine" warning on the screen for maybe 1/4 of a second every couple of days.
Looks to be related to when the car goes over a large bump (e.g. hump back bridge). Any ideas? |

Found mine was the connector on the diesel filter head. Unplugged and plugged in a few times and problem solved.

I don't have access to a T4 unfortunately. I've tried using a Scanguage which reports no errors, and a BMW scanner which doesn't seem to show any obvious errors. |

With the LP pressure sensor unplugged you won't notice any difference in the way the car drives.
The check engine alarm comes on in this instance to let you know the LP fuel pressure sensor is open circuit. |

I've had the fuel filter out twice this year replacing the UBP so it could be that. |
