Fault codes - AdBlue related

Creek_Hunter · 05-20-2023, 11:02 AM

Howdy,

First time poster, glad to be a part of this forum.
Got a 2015 X3 a few weeks ago. Drives like a dream, except for one code that triggers a check engine light.
The code is 8051AD Delivery module, system pressure: Pressure build-up fault
Does anyone have any experience or any suggestions regarding this code? I am using a Topdon in order to scan the car.

Many thanks,

John

You ever figure this out?

Pump or AB injector faulty/clogged is most probable reason for pressure problems.
