VANOS Unit, Bank 2, BMW - E60 M5, E63 M6

Factory-rebuilt VANOS adjustment unit for Bank 2, cylinders 6-10 (driver side) of E60 M5 and E63 M6.

VANOS (or VAN0S) is BMW's variable valve timing system. The VANOS unit is basically a pump and solenoid that rotates the camshaft to make more torque at various RPM. Having a variable camshaft means the S85 V10 engine can make a lot of power in the high RPM without feeling too sluggish in the lower RPM. Obviously any problem with the S85 VANOS unit will have a major effect on performance and drivability, including misfires, fault codes, rough running, sluggish performance, poor fuel mileage, and the dreaded "marbles in a can" rattle sound.

The S85 VANOS is made up of three major parts: the adjuster units (1 for each bank), solenoid packs, and the oil supply and pressure system. The solenoids can be replaced independent of the complete VANOS unit, although new ones are included with this complete VANOS unit.

The telltale rattle of VANOS failure is not always the best indicator of a VANOS issue. The VANOS oil pump and the lines are notorious for losing pressure. A BMW specialist shop should have more advanced tools that can tell which part of the VANOS needs replacing. It's not uncommon for high mileage S85, especially if service was ignored or deferred, to need more than just the VANOS unit replaced.

This item is a complete S85 VANOS unit rebuilt by BMW and carries a two year warranty from BMW North America.

A $50.00 core charge applies to this item. This will be added during order processing. It may be refunded upon the return of your rebuildable original VANOS unit.
