Subject
Power Reduction, FC 2A82 Intake VANOS and/or FC 2A87 Exhaust VANOS Camshaft Faults are Stored in DME
State of affairs
The "Service Engine Soon" (MIL) lamp is illuminated and a power reduction is clearly perceptible. This situation tin can occur after driving for some time with the engine already at full operating temperature. If the ignition is cycled, the engine and so normally performs ordinarily.
The post-obit faults are stored in the DME:
2A82 VANOS intake – stiff; jammed mechanically
2A87 VANOS frazzle – stiff; jammed mechanically
3100 Boost-pressure command, deactivation – heave-pressure level buildup prohibited (N54 only)
Cause
The VANOS faults tin be caused by an bereft oil pressure level supply to the inlet VANOS adjustment unit of measurement. To finer 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 bachelor. When the engine operation requires that the VANOS chop-chop advance or retard the intake or exhaust camshaft, error 2A82 or 2A87 may be gear up if the camshaft is "tardily", or does not reach the target position. In this situation, engine power may exist reduced and a cheque control message is displayed. The consequential fault 3100 tin also be gear up in the DME fault memory too.
PROCEDURE
Perform all applicable exam plans for the faults stored. A mechanical restriction or electrical failure of the VANOS solenoid and/or the electrical circuit tin can cause insufficient oil supply to the VANOS assemblies as well. If the results of the test plans are inconclusive and then keep to stride 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 upshot in non-filtered engine oil being supplied to the engine, thus possibly clogging or dissentious the VANOS solenoids.
Supplant both VANOS solenoids and alter the engine oil and filter. Drive the vehicle to verify effectiveness. If this repair is inconclusive and the mistake returns, continue to pace 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 begetting ledge (1), causing a drib in oil supply to the VANOS unit.

"Replaced both Vanos Solenoids, trouble nonetheless there...."
"I replaced the camshaft ledges and its working fine at present."
