Understanding Your 2013 BMW Alpina B7 SWB xDrive

The 2013 BMW Alpina B7 SWB xDrive (F01 generation) is a hand-finished luxury sedan that combines the N63 4.4L twin-turbo V8 engine with Alpina's performance tuning and BMW's xDrive all-wheel-drive system . The "SWB" designation indicates the standard-wheelbase variant, offering a sportier driving dynamic compared to the long-wheelbase version.

The vehicle is equipped with BMW's Condition Based Service (CBS) system, which monitors driving conditions—including engine temperatures, idle time, stop-and-go driving, and acceleration patterns—to calculate personalized maintenance intervals . The service interval warning is displayed through the vehicle's information center. Outside of CBS-determined services, several critical maintenance items follow fixed mileage intervals.

Important Campaigns for 2013 Alpina B7 Models

Owners of the 2013 Alpina B7 should verify whether two important campaigns have been completed on their vehicle. While some vehicles produced after June 2012 may not be affected, many 2013 models fall within the production window for these N63 engine campaigns.

N63 Customer Care Package (Campaign Code 00 13 47 02 00)

This program applies to F01/F02 vehicles with the N63 engine produced from March 2009 to June 2012 . The campaign includes a 6-point check and, if necessary, replacement of one or more of the following powertrain components :

• Hot-film air mass sensors
• PIEZO high-pressure fuel injectors
• Engine vacuum pump
• Fuel system low-pressure sensor and feed line
• Fresh air intake turbo seals
• Crankcase ventilation lines (hoses)

The procedure also includes an engine oil and filter change and should be completed in conjunction with the timing chain check. A Service Action label with code number 721 should be affixed to the A-pillar if the campaign has been completed .

Timing Chain Inspection (Service Action Label 728)

BMW also issued a service bulletin to check the N63 engine timing chains for stretch . This applies to vehicles with N63 engines produced in the same timeframe. Performing the test plans outlined in the bulletin will detect wear at an early stage. The vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. A Service Action label with code number 728 should be attached to the B-pillar if this campaign has been performed .

Factory Scheduled Maintenance Summary

Based on maintenance schedules for the 2013 Alpina B7, the following fixed-interval services apply :

Engine Oil Change Guidance

Oil Specification

The N63 4.4L V8 engine requires synthetic oil meeting BMW Longlife-01 or Longlife-01 FE specifications. Common viscosity recommendations include 5W-30 and 0W-30. BMW Longlife-04 approved oils are also compatible alternatives.

Oil Change Interval

BMW's Condition Based Service system determines the oil change interval based on actual driving conditions. If the timing chain inspection campaign has been performed on the vehicle, a shorter oil service interval of 12 months or 10,000 miles may have been retrofitted via ISTA/P programming .

Symptoms That May Indicate an Oil Change Is Needed

• Check engine or oil change light illuminated
• Knocking sounds from the engine
• Oil smell inside the vehicle
• Unusual exhaust smoke

Owner Guidance

Given the high-performance nature of the twin-turbo V8 engine, many independent specialists recommend more frequent oil changes for the N63 engine, particularly for vehicles that experience spirited driving or frequent short trips.

Spark Plug Replacement

Spark plugs are a critical maintenance item for the turbocharged N63 engine. The 2013 Alpina B7 uses a motorsport-derived spark plug (Genuine BMW Part No. 12-12-0-054-451) designed for high-performance operation . This plug features specific BMW upgrades compared to standard plugs used in non-M engines, helping to reduce the chance of misfires and knocking from higher boost and high-RPM operation .

Symptoms of Worn Spark Plugs:

• Engine shaking while idling
• Poor fuel economy
• Illuminated check engine light
• Knocking sounds when the engine is running

Bad spark plugs can harm performance and fuel mileage, affect drivability and engine smoothness, and unburnt fuel in the exhaust can shorten the lifespan of oxygen sensors and catalytic converters.

Oxygen Sensor Replacement

Oxygen sensors monitor exhaust gas oxygen content to optimize fuel mixture and emissions control. The maintenance schedule indicates replacement at 120,000 miles and again at 150,000 miles . This service helps maintain optimal fuel economy and minimize exhaust emissions.

Transmission Service

The 2013 Alpina B7 uses an automatic transmission with specific fluid requirements .

Transmission Fluid Specification

The Alpina B7 transmission fluid is equivalent to Shell M-1375.4 . Use only fluid that meets BMW's specifications for the transmission.

Service Interval

A general guideline is to have transmission fluid inspected and potentially changed about every 30,000 to 60,000 miles, depending on driving conditions.

Differential Service (xDrive Models)

For the xDrive models, the differential requires periodic inspection and fluid changes using BMW-approved gear oil.

Differential Fluid Specification

The differential uses fully synthetic 75W-90 gear oil (equivalent to Castrol SAF-XO), specially designed for conventional (non-limited slip) differentials . It provides superior protection at high and low operating temperatures where conventional oils can't.

Brake System Service

Brake Inspection

BMW recommends that front and rear brakes be removed and serviced at least once every 12,000 miles or 12 months . This includes checking the parking brake.

Symptoms Requiring Brake Attention:

• Unusual sounds when braking (squealing, grinding)
• Vibration or pulsation in the steering wheel or pedal
• Burning smell coming from near the tires
• Dashboard brake warning light illuminated

Brake Pad Lifespan

Most brake pads last between 30,000 and 40,000 miles, though this varies significantly based on driving habits and conditions.

Brake Fluid

Brake fluid is hygroscopic, absorbing moisture from the air over time, which can cause corrosion within the braking system and degrade brake pedal feel. Replacement is typically recommended as indicated by the CBS system, with industry guidance suggesting replacement around 2-3 years.
