N63 Engine: Oil Consumption and/or Rough Running Complaints
MODEL:

F10
F12
F13
Situation:
The vehicle may consume engine oil above the permissible specification, and may run rough at times. White or blue smoke may also be seen exiting the exhaust system.
Cause:
The construction material of the crankcase ventilation connection lines and vent pipes may become brittle from engine compartment temperatures.
Procedure:
E70 and E71 produced to 3/2011
F01, F02, F04, F07, F10, F12, F13 produced to 1/2011
1. Remove the engine cover and inspect the crankcase ventilation connecting lines.
Each of the connecting lines will have an index number printed on the connection
closest to the cylinder head cover.
2.Production code
Part Number and Index Number
Example : 7575639-07
The index number is separated from the 7-digit part number by a hyphen.
3. If the index number is "7" or lower, both crankcase ventilation connecting lines and vent pipes need to be replaced.
The improved replacement parts will have an index of "8" or higher.
4. Each cylinder head cover and vent pipe connection has two M6x18 screws attaching these components. The torque specification for these screws is 10 +/- 1.5 Nm.
Important: Do not replace the cylinder head covers for this complaint.
E70 and E71 produced from 3/2011
F01, F02 F04, F07, F10, F12, F13 produced from 1/2011
Inspect the crankcase ventilation connecting lines and vent pipes connections; if found loose, properly secure them.
Important: Do not replace the cylinder head covers for this complaint.

Customers with one of the vehicles above may complain that the engine's oil consumption is "too high," resulting in engine oil top-ups and workshop visits to address the issue before the vehicle displays an engine oil service as being "due." When the vehicle's engine oil drops to the minimum level, a message will display in the vehicle advising the driver to "add 1 quart of engine oil." After topping up and continued operation, the "add engine oil" message may display again before an engine oil service is required and performed.
Cause:
Engines that are fitted with a turbocharger, as part of their normal operation, will consume engine oil at a higher rate than a naturally aspirated engine (non-turbocharged engine). In this case, a "turbocharged" engine could require topping up of the engine oil more frequently.
Procedure:
Engine oil - Topping up
When one of the above vehicles displays a message to add 1 quart of engine oil, BMW recommends adding 2 quarts of engine oil instead. The engine's oil sump design allows the additional quart; the result is a total capacity of 9.5 quarts (9.0 liters) of engine oil.
Engine oil:
Maintenance services and engine repairs
When performing all future engine oil maintenance services and repairs that require draining and refilling the engine oil, the new recommended refill specification is 9.5 quarts (9.0liters) of engine oil.
-The current version of the oil capacities chart, in Group 11 of the Operating Fluids Manual in TIS, has been updated as of 3/2013.
-The current version of ISTA/D is not correct. The updated filling specification will be corrected in ISTA/D 2.38.
Important:
This Service Information bulletin excludes the E72 X6 xDrive50i Hybrid, ActiveHybrid 750i and ActiveHybrid 750Li vehicles, because the hybrid engine oil pan dimensions are smaller.
