Every price we found
| Price | Where | Details | Source |
|---|---|---|---|
| $3,140 | Dealer | Dealer estimate (Sears Auto Imports, Minnetonka MN) for the oil separator, valve cover gaskets, a new seal, an oil change and a diagnostic, February 2008 | [1] |
| $2,655 | Indy | Independent (ORR Motorsports, Eden Prairie MN) quote for the same service plus a water pump, February 2008 | [1] |
| $450 | Indy | "Mechanic wants $450 to fix," oil separator and crankcase vent, 2006 X5 4.4 (N62), shop type not stated, March 2012 | [2] |

- The 2008 dealer and independent quotes are not like-for-like: one includes valve cover gaskets and an oil change, the other adds a water pump. Do not treat either as the price of the separator alone.
- An owner in a 2014 thread was quoted about $800 by a local BMW shop for a heated hose-wrap kit (freeze protection, not a replacement) and said he did not buy it.
