Original BMW Turbo Oil Return Cover for BMW 550i, 650i, 750i, Alpina B6 and B7, X5, and X6 (2008–2019)

The Original BMW turbocharger oil return cover is the flanged fitting on the turbo oil line of the N63 and N63N engines in the BMW 550i, 650i, 750i, Alpina B6 and B7, X5 xDrive50i, and X6. It is the adapter where the turbocharger oil line joins, and BMW gives it the name oil return cover. The current number entered production in June 2017. It supersedes the earlier 11-42-7-577-016, and BMW marks the change as exchangeable retrospectively, so this part also fits cars that left the factory with the older piece. On a turbocharged engine, oil is fed to the turbo bearings and drains back to the sump through the return side, so this joint has to seal reliably at high temperatures. It is sold individually.

Original BMW Parts carry a 24-month parts warranty.

BMW uses this one number across an unusually wide range of chassis. It appears on the F07 5 Series Gran Turismo, the F10 sedan, the F06 6 Series Gran Coupe, the F12 convertible and F13 coupe, the F01 and F02 7 Series, the E70 facelift and F15 X5, and the E71, E72, and F16 X6. It covers both the first-generation N63 and the revised N63N, before and after each model's facelift. If your old part or an earlier invoice shows 11-42-7-577-016, this is its direct replacement.
