The BMW 7 Series is a luxury saloon that often faces specific issues during its MOT tests. Common failures include problems with lights, suspension components, and emissions systems. Fixing these issues can vary in cost, but addressing them proactively can ensure a smoother MOT experience.

Lights and Electrical Systems

One of the most frequent reasons for MOT failures in the BMW 7 Series is related to lights and electrical systems. Common issues include faulty bulbs, broken lenses, and malfunctioning indicators.

Regularly checking and replacing bulbs can help avoid these issues.

Suspension and Steering Components

The suspension and steering systems are crucial for the vehicle’s handling and safety. MOT failures often arise from worn-out shock absorbers, damaged bushings, or play in the steering components.

Regular maintenance and inspections can help prolong the life of these components.

Brake System Failures

Brake system failures are another common issue for the BMW 7 Series during MOT tests. Problems can include worn brake pads, damaged discs, or leaks in the brake lines.

Keeping an eye on brake performance and addressing any warning signs early can prevent costly repairs.

Emissions and Exhaust System

The emissions system is a critical area of concern for the BMW 7 Series. Common failures include issues with the catalytic converter, exhaust leaks, or malfunctioning sensors.

Regular servicing can help catch emissions issues before they lead to an MOT failure.

Tyres and Wheel Alignment

Tyres are essential for safety and performance, and they are a common reason for MOT failures. Issues can include insufficient tread depth, uneven wear, or damage to the sidewalls.

Regularly checking tyre condition and maintaining proper inflation can help avoid these issues.

Bodywork and Structural Integrity

Finally, the bodywork and structural integrity of the BMW 7 Series can also lead to MOT failures. Common problems include rust, corrosion, or damage to the chassis.

Addressing rust can vary significantly in cost, depending on the extent of the damage. Keeping the vehicle clean and protected from the elements can help prevent these issues from developing.

BMW 7 Series recall record

46 recalls have been issued for the BMW 7 Series, between 1999 and 2026.

  1. Checking and re-securing the air-conditioning wiring harness

    R/2026/092

    Issued 17 March 2026

    The Safety Recall relates to the air-conditioning wiring harness located behind the dashboard. On the affected vehicles the wiring harness was fixed very close to a screw connection on the interior microfilter housing cover. The microfilter of the air conditioning system will be regularly replaced as part of the oil service. It cannot be ruled out that cables may be damaged when replacing the microfilter during a workshop visit. The filter cover has to be removed from the lower part of the instrument panel. After replacing the filter the cover has to be refitted at which point the wires may become damaged or trapped. If the wiring harness is damaged this could lead to malfunctions of the air conditioning system as well as to a short circuit. In case of a short circuit a sensor may overheat while the vehicle is in operation. As a result smoke may develop from the instrument panel and subsequently a fire cannot be ruled out.

    Remedy:On the affected vehicles the air-conditioning wiring harness will be checked repaired if necessary and re-secured in a modified fixing.

    Affects cars built Jul 2022 to Apr 2025

  2. Replace the Engine Starter Motor

    R/2025/405

    Issued 27 October 2025

    For affected vehicles there is a concern involving water ingress and corrosion to the starter motor for where a short circuit cannot be ruled out. It is strongly recommended to park the vehicle outdoors and not in the immediate vicinity of buildings until the repair has been carried out.

    Remedy:Replacement of the starter motor.

    Affects cars built Aug 2016 to Feb 2019

  3. Hydraulic Brake System Unit Replacement

    R/2024/414

    Issued 24 October 2024

    On affected vehicles the brake servomotor was improperly welded. The weld seam might not withstand the stresses caused under high brake pressure leading to a requirement for a higher brake effort increasing the braking distance.

    Remedy:Affected vehicles will have the hydraulic unit of the brake system replaced.

    Affects cars built Apr 2024 to Jun 2024

  4. Replace Double Universal Joint (Steering)

    R/2024/409

    Issued 21 October 2024

    On affected vehicles there may have been a deviation in the production of the double universal joint on the steering column. Certain steering movements could result in the component failing.

    Remedy:Affected vehicles will have the double universal joint replaced.

    Affects cars built Jun 2024 to Sept 2024
