The 2011 BMW Alpina B7 xDrive is a high-performance luxury sedan powered by a 4.4-liter twin-turbocharged N63 V8 engine paired with an 8-speed Sport Automatic transmission. With 500 horsepower and 516 lb-ft of torque, it can accelerate from 0-60 mph in just 4.2 seconds. The B7 xDrive offers an impressive blend of performance and comfort, but like any vehicle, it has its share of reported issues.

Engine

  • N63 V8 Engine:

    • High-Pressure Fuel Pump Failures: Symptoms include loss of power, rough idling, and difficulty starting. The solution is to replace the fuel pump, which can cost $1,000-$2,000.
    • Timing Chain Guide Failure: A faulty timing chain guide can cause the chain to slip or break, resulting in engine damage. Replacement of the guide requires removing the engine and can cost $5,000-$10,000+.

Transmission

  • 8-Speed Sport Automatic:

    • Shifting Problems: Harsh shifting or slipping gears may occur due to worn clutches or faulty solenoids. Repair costs vary depending on the issue, but can range from $500-$2,000+.

Suspension

  • Adaptive Suspension System:

    • Air Spring Leaks: Worn or damaged air springs can cause the suspension to sag or become uneven. Replacement of the air springs can cost $1,000-$2,000 per corner.

Electrical

  • Integrated Control Module (ICM) Failures: The ICM is responsible for controlling various electrical functions. Failures can cause a range of issues, including electrical system malfunctions and loss of power. Replacement of the ICM can cost $1,500-$2,500.
  • Battery Discharge: Faulty battery sensors or electrical drain can cause the battery to discharge prematurely. Diagnosis and repair can cost $200-$500.

Exterior

  • Headlight Condensation: Moisture buildup inside the headlights can occur due to faulty seals. Replacement of the headlights can cost $1,000-$2,000 per side.

Interior

  • Climate Control Malfunctions: Faulty sensors or actuators can cause the climate control system to malfunction, resulting in inconsistent temperature control. Repair costs can range from $200-$500.
  • Heated Seat Failures: Malfunctioning heating elements or wiring can cause the heated seats to stop working. Repairing or replacing the heating elements can cost $500-$1,000 per seat.

Summary:

While the 2011 BMW Alpina B7 xDrive is generally a reliable vehicle, it has some potential issues to be aware of. The engine and transmission issues can be costly to repair, but the electrical, exterior, and interior issues are typically less severe. Overall, the B7 xDrive is a high-performance sedan that offers a blend of luxury and sportiness, but potential buyers should be prepared for the possibility of some repairs down the road.
