On the 2013-2015 BMW 7 Series N63TU1, bMW SIB 01 01 22 identifies specified U.S.-specification F01/F02 750i, 750Li and ALPINA B7 variants from model years 2013-2015 with the N63TU1 engine for an oil-consumption diagnosis and related-repair settlement path. The lawsuit alleged excessive oil use and BMW denied the allegations. BMW permits turbocharger replacement only when the prescribed inspection confirms leakage; the bulletin does not establish age-, heat- or mileage-based turbo failure.

This issue also affects: BMW 6 Series, BMW X5

Common Symptoms

  • Low-oil warning before the scheduled oil service
  • Repeated need to add engine oil between services
  • BMW inspection confirms a leaking turbocharger or turbo oil-return component

How to Fix

Confirm the exact chassis, N63TU1 engine, production date, engine serial number, VIN and current eligibility, then follow BMW electronic oil-level measurement and leak-inspection procedures. Repair only the component supported by the documented test result; replace turbochargers only when leakage is confirmed under the current instructions. Do not promise historical settlement coverage. ShowMeTheParts returned six exact 2014 750i/750i xDrive turbo oil-return-line fitments, but catalog fitment does not prove a leak, oil-consumption cause or repair role, so no commerce link is approved.

On the 2009-2015 BMW 7 Series, the N63 twin-turbo V8 places the turbos inside the vee, and the trapped heat cooks the plastic timing chain guides until they crack and break apart. Debris from a shattered guide lets the chain go slack, so it stretches, throws timing correlation codes, and can jump a tooth - at which point one whole bank stops firing and the driver gets a Drive Train Malfunction with reduced power. Owners on the F01 chassis have reported broken guides and a jumped chain around 100,000-120,000 miles, often preceded for months by a rattle or grinding noise during the first few seconds after a cold start. Early N63 engines (roughly 2009-2013) were the worst and were covered in part by the Customer Care Package rework.

This issue also affects: BMW 1 Series, BMW 2 Series Active Tourer, BMW 3 Series

Common Symptoms

  • Rattle or grinding for a few seconds at cold start
  • Drive Train Malfunction warning
  • One bank of cylinders stops firing
  • Rough running and severe loss of power
  • Check engine light with timing correlation codes

How to Fix

Do not ignore a cold-start rattle on an N63. Pull the DME for timing correlation codes and check the chain wear with a scope before it jumps. The repair replaces the complete kit - chains, guides, tensioners and sprockets on both banks - because reusing any one worn part causes a repeat failure. The engine has to come out and be largely disassembled; it is roughly a 40-hour job, which is why quotes land in the five-figure range at a dealer. If the chain has already jumped, the valves may be bent and the heads need inspection.

Typical repair cost:$6,000 - $14,000

On the 2009-2015 BMW 7 Series N63, the N63 V8 engine uses high-pressure direct injection fuel pumps (HPFP) that commonly fail between 60,000-100,000 miles. The HPFP is driven by the engine camshaft and operates at extremely high pressures (2,900+ PSI). Internal wear and seal failures cause fuel pressure loss, leading to rough running, misfires, and no-start conditions. The N63 has two HPFPs (one per cylinder bank) that often fail together. Failed pumps can contaminate the fuel system with metal particles, requiring fuel system flush.

This issue also affects: BMW 1 Series, BMW 5 Series, BMW 6 Series

Common Symptoms

  • Rough idle or engine stumble
  • Long cranking or no-start condition
  • Check engine light with fuel pressure codes (P0087, P0088)
  • Loss of power or hesitation
  • Engine misfires under load
  • Fuel smell from engine bay

How to Fix

Replace high-pressure fuel pump(s). BMW recommends replacing both HPFPs together on N63 engines. Flush fuel system if metal contamination is present. Use only OEM BMW or Bosch fuel pumps - aftermarket pumps have poor reliability. Labor is 4-6 hours. Some owners report multiple HPFP failures over vehicle life. N63 Customer Care Package may cover HPFP repairs on eligible VINs. Consider extended warranty for N63-powered cars.

On the 2009-2015 BMW 7 Series, the N63 engine uses BMW's Valvetronic system (variable valve lift) which commonly fails. The Valvetronic eccentric shaft motor wears out or burns out, causing rough running and limp mode. The system also suffers from carbon buildup on the Valvetronic mechanism. Failure typically occurs between 60,000-100,000 miles. Symptoms include rough idle, reduced power, and check engine lights. This is a separate issue from the turbo problems but equally common on early N63 engines. The N63 has two Valvetronic motors (one per cylinder bank).

This issue also affects: BMW 6 Series, BMW 8 Series, BMW M3

Common Symptoms

  • Rough idle or engine vibration
  • Check engine light with Valvetronic codes (P1163, P1164)
  • Limp mode activation (reduced power)
  • Poor throttle response
  • Increased fuel consumption
  • Rattling noise from valve cover area

How to Fix

Replace Valvetronic eccentric shaft motor(s). Often both motors need replacement since wear is similar. Clean carbon buildup from Valvetronic mechanism during repair. N63 Customer Care Package may cover this repair on eligible VINs. Labor is 6-10 hours. Some shops recommend replacing Valvetronic motors preventively at 80,000 miles to avoid being stranded. Extended warranty highly recommended for N63-powered 7 Series.

On the 2011-2015 BMW 7 Series, the 740i/740Li built with the N55 single twin-scroll turbo develops a metallic chattering or rattling from the turbo at light throttle and on deceleration, typically between about 2,000 and 3,500 rpm, and often loudest right after a cold start. The cause is wear in the turbine-side wastegate flapper mechanism: the stamped-steel flapper, its pivot pin and the actuator linkage develop play, and the flap bounces against its seat instead of closing cleanly. It usually appears past roughly 80,000 miles. It is not immediately destructive, but the play worsens and can eventually cause boost control faults and underboost codes.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 5 Series

Common Symptoms

  • Metallic rattle from the turbo at light throttle
  • Chattering noise on deceleration around 2000-3500 rpm
  • Noise loudest at cold start and disappears when the turbo spools
  • Occasional boost-related check engine light

How to Fix

BMW's TSB remedy is to install a wave spring between the wastegate actuator lever arm and the turbine housing to take up the play - the cheapest legitimate fix and worth asking about first. If the flapper and pivot are worn out, a wastegate flapper/turbine-flap rebuild kit rebushes the pivot and replaces the flapper, which requires removing the turbo. A full turbocharger replacement is the dealer default and by far the most expensive path. Ignore any advice to simply increase actuator rod preload as a permanent fix; it masks the noise and can cause overboost or underboost faults.

Typical repair cost:$250 - $2,500

On the 2009-2022 BMW 7 Series, the 7 Series iDrive infotainment system experiences head unit failures across generations, with the CIC (Car Information Computer) in F01 models and NBT (Next Big Thing) in G11 models being particularly problematic. Symptoms include screen blackouts, random reboots, navigation freezing, and loss of Bluetooth connectivity. The issues are often caused by failing hard drives (CIC) or eMMC storage degradation (NBT) within the head unit.

Common Symptoms

  • iDrive screen going black randomly while driving
  • System rebooting itself repeatedly (boot loop)
  • Navigation freezing or showing incorrect position
  • Bluetooth not connecting or dropping connections
  • Loss of backup camera feed
  • Climate control display not responding through iDrive
  • No audio output from any source

How to Fix

For CIC units (F01): replace the internal hard drive with an SSD upgrade, or replace the entire CIC module. For NBT units (G11): replace the head unit or have the eMMC chip reflowed/replaced by a specialist. Software updates from BMW can address some stability issues. Many aftermarket specialists offer rebuilt head units at 40-60% of dealer pricing. The unit must be coded to the vehicle VIN after replacement.

On the 2009-2015 BMW 7 Series, the N63's direct injectors sit in the hottest part of a hot-vee engine and fail early, either leaking down and washing the cylinder or losing flow entirely. The result is a persistent misfire isolated to one cylinder that follows the injector when you swap it to another bore - the diagnostic that separates an injector from a coil, plug, or HPFP problem. BMW went through several injector revisions and ran an index-level campaign, replacing early injectors with index 11 or higher on affected cars; checking the index number stamped on each injector is a standard step when diagnosing N63 misfires. Owners on BimmerFest report chasing a cylinder-specific misfire through coils, plugs and even swapped high-pressure fuel pumps before the injector proved to be the culprit.

This issue also affects: BMW 3 Series, BMW M3, BMW Z4

Common Symptoms

  • Rough idle
  • Persistent misfire on one cylinder
  • Check engine light flashing under load
  • Fuel smell from the exhaust
  • Reduced power / engine malfunction message

How to Fix

Read the misfire counters per cylinder, then swap the suspect injector to a different cylinder - if the misfire moves, the injector is bad. Check the injector index level; anything below the current index should be updated. Injectors must be coded to the DME with their calibration numbers after replacement, and BMW specifies new decoupling elements and Teflon seals. Many N63 injector replacements have been covered free of charge under BMW's extended injector program, with a 2-year warranty on the replaced parts even on out-of-warranty cars - ask the dealer before paying. Replace plugs at the same time since the washed cylinder has fouled them.

On the 2002-2023 BMW 7 Series, bMW 7 Series models equipped with air suspension commonly experience compressor and air strut failures. The air suspension compressor runs frequently and wears out between 60,000-120,000 miles. Air struts develop leaks from deteriorating rubber airbags. Symptoms include suspension warning lights, sagging corners, and harsh ride quality. The system requires all four air struts and the compressor for proper operation. This affects E65/E66, F01/F02, and G11/G12 generations with air suspension option. Repair costs are extremely high due to specialized components.

Common Symptoms

  • Suspension malfunction warning on dashboard
  • Vehicle sits low or sags at one corner
  • Compressor runs constantly (whining sound)
  • Harsh ride quality or loss of adaptive damping
  • Air suspension inactive message on iDrive
  • Hissing sound from air leaks

How to Fix

Replace failed air struts or compressor. Individual air struts can be replaced, but often multiple fail together. Compressor replacement is 3-5 hours labor. Some owners convert to conventional coil springs ($1,500-2,500) to avoid repeat air suspension repairs. Air strut replacement requires specialized tools and calibration. OEM BMW parts are extremely expensive; some aftermarket options (Arnott) available at lower cost but with mixed reliability.

Typical repair cost:$2,500 - $6,000
