2011 BMW 7 Series Problems: 40 Known Issues

On the 2009-2012 BMW 7 Series N63, bMW provides a timing-chain elongation test for the original N63. A failed test calls for both chains to be replaced; the bulletin does not establish universal guide breakage or a failure mileage. It applies to F01/F02 cars with the original N63 produced September 2008 through June 2012. Confirm actual build and current procedure. It does not cover N63TU or Alpina engines.

On the 2009-2011 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, bMW states that the crankcase ventilation connecting lines and vent pipes on the original N63 V8 can become brittle from engine-compartment heat. The engine may then consume oil above specification and run rough at times, and white or blue smoke may come from the exhaust. This applies to F01/F02 750i, 750Li and their xDrive versions with the original N63 engine. Bulletin 11 07 12 calls for replacing the lines on F01/F02 built up to January 2011 if their index number is 7 or lower; the 10-year/120,000-mile warranty extension (01 12 15) lists the F01 750i and F02 750Li of model years 2009-2011 and the 750i xDrive and 750Li xDrive of model years 2010-2011, built up to late February 2011. The N63 Customer Care Package (11 06 14) covers F01/F02 built September 2008 to June 2012.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, the original N63 V8 can consume engine oil above specification. BMW names leaking valve stem seals as one cause, with smoke from the tailpipe on starting or hard acceleration and deceleration, or oil-fouled spark plugs, alongside the high oil use. This applies to F01/F02 7 Series with the N63 built September 2008 to June 2012 (valve seal bulletin 11 08 15). The Bang class-action settlement bulletin 01 29 18 lists the F01 750i (MY 2009-2012), F01 750i xDrive (MY 2010-2012), F02 750Li (MY 2009-2012) and F02 750Li xDrive (MY 2010-2012), plus ALPINA B7 as class vehicles.

On the 2009-2015 BMW 7 Series, engine oil can leak from the center of the car, with residue visible between the engine oil pan and the transmission bell housing. This applies to F01/F02 7 Series (including ALPINA B7) with the N63 or N63TU engine, per bulletin 11 09 16 (no production dates given).

On the 2011-2012 BMW 7 Series N63, bMW says a high-pressure pump quantity-control valve can fail, producing an engine-malfunction warning and reduced output. The service action applies to a specific original-N63 production window. F01/F02 original N63 produced January 1 through December 1, 2011, only when the action is open for the VIN. Model year alone does not establish eligibility; affected production may cross model-year labels. N63TU is excluded.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, bMW extended the limited warranty on the engine vacuum pump of N63-engined cars to 10 years/120,000 miles for defects in materials and workmanship, and lists the vacuum pump among the parts checked and replaced if necessary in the N63 Customer Care Package. Neither document describes the failure symptoms. This applies to F01/F02 750i, 750Li, 750i xDrive and 750Li xDrive with the original N63. The N63 Customer Care Package (bulletin 11 06 14) covers F01/F02 built September 2008 to June 2012; the warranty extension (bulletin 01 08 15) lists F01 and F02 750i (model years 2009 to 2011) and 750i xDrive (model years 2010 and 2011) built up to late February 2011 (February 25 or 28, 2011 depending on body style).

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, the gasket seal ring of the engine oil pump volume control valve, near the oil filter, can leak engine oil because it may have been damaged during assembly. Bulletin 11 08 12 covers F01/F02 7 Series with the N63 engine.

On the 2009-2015 BMW 7 Series, the lower display of the instrument cluster can go blank intermittently, so the trip computer, outside temperature and Check Control messages do not show; or the whole cluster display can switch off intermittently with fault B7F689. BMW names instrument cluster software. The bulletins cover F01/F02 cars without option 6WB (multifunction instrument display): 62 07 15 for cars produced up to April 30, 2016, and 62 10 15 for cars produced up to October 31, 2015.

On the 2009-2022 BMW 7 Series, for F01/F02 cars, electronics specialists document a blank screen, repeated restarting, freezing or loss of audio. These symptoms do not establish a hard-drive or memory-chip failure. Early F01/F02 models use CIC, later F01/F02 use NBT, and G11/G12 use NBT Evo then MGU; identify the installed unit before selecting a repair.

On the 2010-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, on F01/F02 cars with the original N63, a "High Battery Discharge Warning" can appear after starting when the 12-volt battery is heavily discharged or faulty. The N63 class-action settlement covered battery drain that can cause premature battery failure. This applies to F01/F02 with the N63 built September 2009 to July 2012 (bulletin 61 03 13); the battery benefit of the settlement (01 22 18) lists the F01 750i (MY 2009-2012), F01 750i xDrive (MY 2010-2012), F02 750Li (MY 2009-2012) and F02 750Li xDrive (MY 2010-2012), plus ALPINA B7 as class vehicles.

On the 2010-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, various Check Control messages including "Electronic Malfunction" can appear, with functions such as the windshield wipers (inoperative or stuck on), trunk opening, central locking or rear power windows not working. BMW names a junction box electronics software error. Bulletin 61 02 12 covers F01/F02 7 Series produced from September 1, 2009.

On the 2009-2014 BMW 7 Series, when the car is locked with one key and later unlocked at the door handle with the second key, the seats move to the right memory position but the outside mirrors do not. BMW names a software error in the driver's seat module. It affects only F01/F02 cars with option 322 (Comfort Access) produced up to March 2014, per bulletin 65 21 13.

On the 2009-2015 BMW 7 Series, the side view camera can show no picture when reverse is engaged or the camera button is pressed, because water entering the cable assembly corrodes the connector pins at the camera, or the cable connection is poor. It affects only F01/F02 with option 5DL (side and top view cameras) or option 5DK (side view camera), per bulletin 66 08 14.

On the 2009-2015 BMW 7 Series, the Condition Based Service due date for the oil service and vehicle check can reset to 01/2000 and cannot be updated, with no fault stored. BMW names an instrument cluster software error. Bulletin 62 06 13 covers F01/F02 7 Series cars.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, a software error in the Intelligent Battery Sensor can store a wrong state of charge, so the car sporadically shows "Increased battery discharge!" (sometimes also "Battery charge level low!") at start-up although the battery has no problem. Bulletin 61 22 13 covers F01/F02 7 Series produced up to April 2013.

On the 2010-2015 BMW 7 Series, the driveline can shudder or vibrate when taking off from a stop or accelerating at highway speed. BMW lists several possible causes, including the engine, wheels and tires, suspension, and internal wear on the transfer case clutch plates. A separate bulletin covers low-mileage cars (under 12,500 miles) built with front and rear differentials of mismatched gear ratios, which also brings a chassis stabilization warning. This applies to F01/F02 7 Series with xDrive, per bulletins 27 04 15 and 27 03 15 (27 03 15 excludes Alpina B7 xDrive).

On the 2011 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, the flexible disc (giubo) that connects the rear driveshaft to the transfer case can crack because of excessive angular load. Service action 26 05 16 covers F01/F02 7 Series with xDrive built March 1 to April 29, 2011. Only cars built in that window are included; the VIN decides.

On the 2010-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, the DSC, ABS and brake warning lamps can light up, sometimes with a "Chassis Control System failure" message, with internal-error faults stored in the transfer case control unit.

On the 2009-2015 BMW 7 Series, the rear differential mount bushing in the rear axle carrier can show cracking. BMW says light surface cracking is normal, but a bushing cracked all the way through must be replaced. Bulletin 33 01 15 covers the F01/F02 7 Series.

On the 2010-2013 BMW 7 Series, a cracking or knocking noise can come from the driveline on sharp turns below about 15 mph. BMW names a software calibration error in the transfer case control unit as the cause. Bulletin 27 02 13 covers F01/F02 cars with xDrive built up to May 2013.

On the 2009-2015 BMW 7 Series, the trunk may open while the car is locked, or after stopping at a light, when the trunk button on the key is pressed accidentally. Bulletin 51 30 16 covers the F01/F02 7 Series and gives no production dates.

On the 2009-2015 BMW 7 Series, oil used as a separating medium between the rain/light sensor gel pad and the windshield can leak out around the sensor. BMW states it does not impair the sensor's function. Bulletin 61 30 17 covers the F01/F02 7 Series.

On the 2009-2014 BMW 7 Series, the trunk lid may not stay in the fully open position because a tension spring can come loose from its retaining bolt. It affects only F01/F02 7 Series of model years 2009 to 2014 without option 316 (automatic trunk lid), per service action 51 30 15. Cars with the automatic trunk lid are not included; the VIN decides whether it is open.

On the 2009-2015 BMW 7 Series, water or misting can appear inside the headlight lenses. BMW names water entering the housing or condensation as the causes. Bulletin 63 05 16 covers F01/F02 7 Series headlights.

On the 2002-2022 BMW 7 Series, a drop in ride height or unusually frequent compressor operation can indicate an air-suspension leak, but uneven height can also involve the valve block. Diagnose the actual fault. On equipped E65/E66 and F01/F02 cars the air springs are at the rear; G11/G12 use air springs on both axles.

On the 2009-2015 BMW 7 Series, a rubbing or creaking noise can come from the front axle over uneven roads because the vibration absorber on the front axle support presses against the axle support bracing. Bulletin 31 01 14 covers F01/F02 cars with xDrive.

On the 2009-2015 BMW 7 Series, cracking noises can come from the front axle when maneuvering at low speed or turning the steering wheel while stationary.

On the 2009-2015 BMW 7 Series, a noise can come from the left or right front seat base on rough roads because the riveting of the seat control bracket to the metal seat base is too loose. Bulletin 52 04 12 covers F01/F02 7 Series.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, a rattling or clattering noise can come from the front passenger footwell on rough roads because the footwell trim contacts the side cover of the instrument panel. Bulletin 51 29 12 covers F01/F02 produced August 2008 to July 2012.

On the 2009-2015 BMW 7 Series, the surface of one or more climate control panel buttons can peel, making the symbols unreadable. BMW names ingredients in skin care products such as sunscreen and hand lotion as the cause. Bulletin 64 01 13 covers F01/F02 7 Series cars.

On the 2009-2015 BMW 7 Series, the airbag warning light can come on, sometimes only intermittently, with a front-passenger seat occupancy detection fault stored. BMW states the capacitive occupancy mat sets the fault when it detects moisture on the mat. Bulletin 65 04 14 covers the F01/F02 7 Series and gives no production dates.

On the 2011-2015 BMW 7 Series, after engine start, an SOS malfunction Check Control message can appear sporadically because the telematics unit detects a signal error during its aerial self-test. Bulletin 84 07 15 covers F01/F02 produced January 1, 2011 to March 31, 2016; a 2011 car built before January 2011 is not included.

On the 2009-2012 BMW 7 Series N63, bMW includes piezo fuel injectors in the N63 Customer Care Package inspection. Replacement depends on the inspection result; the bulletin does not establish that every injector fails, a common mileage, or heat as the cause. It applies to F01/F02 cars with the original N63 produced September 2008 through June 2012. Verify VIN, engine, prior completion and current eligibility. It does not cover N63TU, Alpina or later production.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, the Drivetrain Malfunction message can appear with high-pressure fuel quantity control valve faults stored. BMW names a loose electrical connection at the quantity control valve relay as the most likely cause. This applies to F01/F02 7 Series (including ALPINA B7) with the N63 engine, per bulletin 12 37 15.

On the 2009-2015 BMW 7 Series, bMW states that certain air-conditioning condensers can fail prematurely because of corrosion. It affects F01/F02 7 Series cars fitted with condenser part number 9255983 dated on or before November 11, 2013; affected cars show the service action as open by VIN.

On the 2010-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, a whistling noise can come from the center fresh-air vents during the first 3 to 10 minutes of heating at low outside temperatures, at low fan speed with the center vent wheel turned to red. BMW names unfavorable airflow against the mixing flaps. Bulletin 64 01 11 covers F01/F02 cars produced April 22, 2010 to August 30, 2012.

On the 2009-2014 BMW 7 Series, the engine warning light can come on with a fuel tank ventilation and purge system micro-leak fault stored. BMW names contamination of the natural vacuum leak detection (NVLD) pressure switch contacts as a cause. It affects only F01/F02 produced to May 2014 that are fitted with the Natural Vacuum Leak Detection (NVLD) module, per bulletin 16 15 14; the VIN decides which leak-detection system the car has.

On the 2010-2013 BMW 7 Series, the remaining brake pad life shown by Condition Based Service can disagree with the real pad thickness, showing distances that are too high or too low, because of the software model of pad wear. Bulletin 34 02 13 covers F01/F02 cars produced August 31, 2009 through February 27, 2013.

On the 2009-2012 BMW 7 Series N63B44O0 (original N63) 4.4L twin-turbo V8, in low-load driving at low outside temperatures, the engine computer can store a thermostat fault and turn on the Service Engine Soon light even though the thermostat works and the engine runs at the correct temperature. BMW names unfavorable engine software diagnostics as the cause. Bulletin 12 18 13 covers the F01/F02 with the N63 engine.
