I've tried to clear them up, trying to see a pattern but they keep coming back. Jb3 is out and back to stock.
Im having long crank but no hpfp codes, it goes into limp mode right as soon as it starts.
I even switched the vanos solenoids from top to bottom to see if anything changes but nothing..Im going to try to replace them both just in case...
when the car starts it sounds a little rough but no crazy sounds, its drivable on limp mode but no power...
Im out of warranty so no dealership trip just yet, maybe if I cant find a solution, Im trying to keep this thread informative, so no stupid comments..
ANY IDEAS?

SUBJECT
Power Reduction, FC 2A82 Intake VANOS and/or FC 2A87 Exhaust VANOS Camshaft Faults are Stored in DME
MODEL
E82 and E88 (1 Series) with N51, N52K and N54 engines produced from 1/2008
E90 and E91 (3 Series) with N52 engine produced from 3/2005 through 6/2006
E90, E91, E92 and E93 (3 Series) with N51, N52K and N54 engines produced from 7/2006
E85 and E86 (Z4) with N52 engine produced from 1/2006
E83 (X3) with N52K engine produced from 9/2006
E60 and E61 (5 Series) with N52, N52K and N54 engines produced from 3/2005
E70 (X5) with N52K engine produced from 10/2006
E71 (X6) with N54 engine produced from 1/2008
SITUATION
The “Service Engine Soon” (MIL) lamp is illuminated and a power reduction is clearly perceptible. This situation can occur after driving for some time with the engine already at full operating temperature. If the ignition is cycled, the engine then usually performs normally.
The following faults are stored in the DME:
2A82 VANOS intake – stiff; jammed mechanically
2A87 VANOS exhaust – stiff; jammed mechanically
3100 Boost-pressure control, deactivation – boost-pressure buildup prohibited (N54 only)
CAUSE
The VANOS faults can be caused by an insufficient oil pressure supply to the inlet VANOS adjustment unit. To effectively move the camshafts to the target positions in the specified time and under all engine conditions, sufficient oil pressure supply to the VANOS control pistons must always be available. When the engine operation requires that the VANOS quickly advance or retard the intake or exhaust camshaft, fault 2A82 or 2A87 may be set if the camshaft is “late”, or does not reach the target position. In this situation, engine power may be reduced and a check control message is displayed. The consequential fault 3100 can also be set in the DME fault memory as well.
PROCEDURE
Perform all applicable test plans for the faults stored. A mechanical restriction or electrical failure of the VANOS solenoid and/or the electrical circuit can cause insufficient oil supply to the VANOS assemblies as well. If the results of the test plans are inconclusive then proceed to step 2.
The oil filter cap insert may have been inadvertently removed during the vehicle’s last oil service. If this insert is not installed, it will result in non-filtered engine oil being supplied to the engine, thus possibly clogging or damaging the VANOS solenoids.
Replace both VANOS solenoids and change the engine oil and filter. Drive the vehicle to verify effectiveness. If this repair is inconclusive and the fault returns, continue to step 4.
If the oil filter cap is found intact, it is possible that the camshaft hook ring seals (3) have worn a groove into the camshaft bearing ledge (1), causing a drop in oil supply to the VANOS unit.
Camshaft bearing ledge
Intake camshaft
Hook ring seals
Note the deep grooves worn into the intake camshaft bearing ledge by the camshaft hook ring seals.
Acceptable camshaft bearing ledge – minor wear marks from the rotation of the camshaft are normal.
If the oil filter cap insert is found to be missing, then the entire oil filter housing cap must be replaced (refer to the EPC). If excessive wear to the camshaft bearing ledge is found, it is only necessary to replace the camshaft hook ring seals and the affected camshaft bearing ledge.
Im having long crank but no hpfp codes, it goes into limp mode right as soon as it starts.
I even switched the vanos solenoids from top to bottom to see if anything changes but nothing..Im going to try to replace them both just in case...
