BMW 440 reliability
The BMW 440 fails its MOT less often than most cars up to 5 years old: 11.3% of 2,514 tests failed in 2023, against 14% on average.
18 DVSA recalls for the BMW 440
Most cover a batch of cars built in a set period, and dealers fix them free. Sweep’s check shows the recalls for a car’s age and whether the DVSA has one outstanding.
Replace the Engine Starter Motor
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.

Takata Driver and/or Passenger Airbag Recall (Global VINs)
Affected vehicles are already included in Safety Recalls within the markets they have previously resided in. The vehicles may be fitted with a driver and/or passenger airbag/s which if deployed may do so with excessive force causing sharp metal fragments to be released this may cause serious injury which could prove fatal to people in the vicinity.
Fix: Vehicles will have the affected airbags checked and if necessary replaced.

Check Driver’s Airbag for Conversion Takata SDI & PSDI-5
Affected vehicles may have had a retrofit or conversion of the airbag using a previously recalled airbag variant which if deployed may do so with excessive force causing sharp metal fragments to be released this may cause serious injury possibly fatal to people in the vicinity. The original factory fitment airbag for the vehicle is not affected.
Fix: Vehicles will have the airbag checked and if necessary replaced.

Software fault in crankshaft sensor
The affected vehicles may be equipped with a crankshaft sensor with a software fault.
Fix: On the affected vehicles the crankshaft sensor will be replaced with a new version.
Recalled models: 4 SERIES · 1,642 vehicles
Software fault with crankshaft sensor
The affected vehicles may be equipped with a crankshaft sensor with a software fault. The crankshaft sensor cannot process the signal values from the crankshaft transmitter due to an improper firmware level. The firmware does not compensate sufficiently the temperature gradients and the magnetic field strength of the sensor electronic. If the crankshaft sensor cannot process the signal values from the transmitter the Digital Diesel Electronic (DDE) will notice that and change to the emergency operation mode. The emergency mode will be displayed by the check control message �engine malfunction�. The driver may notice a rough running engine and a reduced driving power (70%). However an engine stalling during driving conditions cannot be excluded.
Fix: On the affected vehicles the crankshaft sensor will be replaced with a new version.
