The VANOS system is BMWs version of variable valve timing and can be found on the intake and or exhaust camshafts. The system uses a pair of electrically actuated solenoids that direct the flow of pressurized oil to the VANOS gears.

What is a VANOS on a mini?

The VANOS system is BMWs version of variable valve timing and can be found on the intake and or exhaust camshafts. The system uses a pair of electrically actuated solenoids that direct the flow of pressurized oil to the VANOS gears.

What is VANOS adaptation?

VANOS adaptations are no different than fuel trims and spark advance/retard, the engine management will adjust based on sensor readouts. ! Needs fuel trim because injected fuel volume is unknown — an opened loop system compared to cams timing which is a closed loop system with known feedback measured angles.

How much does it cost to fix VANOS?

Total cost for the new Vanos + labor (minus core charge for original Vanos unit from Dr Vanos) will be approx $600-$700.

What causes VANOS failure?

The first issue is o-ring failure. These rings are made from rubber and can break down and deteriorate naturally over time. The second most common issue is with the solenoids, which can get clogged. If dirt and debris block the solenoids, they will not be able to work properly.

What are the fault codes 288D and 2845?

It took a bit to trace the fault codes down. 288d is vanos actuator exhaust movement, 2845 is for vanos exhaust as well. I could not find an exact match for the other codes but I suspect them to be related to exhaust vanos adaptation that sets when the other codes set.
