BMW X4 recalls

The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits.

Fix: On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine.

The fault affects the brake system in particular the brake calipers on the rear axle. Because of a faulty coating hydrogen gas (approximately 10 ml) could be created in the coating of the piston of the brake caliper. This will be completely outgassed during the first 2 months after the production process causing longer brake pedal travel. Under certain circumstances the relevant brake pressure cannot be build up in the rear brake circuit. As a result the brake force of the system may be reduced by up to 30%. The driver may feel a soft brake pedal and a reduction of the brake performance. In certain cases the rear brake circuit could fail leading to increased risk of an accident.

Fix: On the affected vehicles the brake system will be bled.

The sealing cap of the pressure-limiting valve in the fuel tank delivery module may be damaged. This concern could lead to a reduction in fuel transfer from the left side to the right side of the fuel tank. Therefore it is possible for the engine to stall even though the fuel gauge would show fuel present.

Fix: Recall the vehicles that are likely to be affected and check the fuel pressure of the delivery module and the distance of the cap on the pressure-limiting valve. Where necessary the delivery module will be replaced.
