Engine and gearbox

The 2014 to 2019 BMW 3 Series features a variety of engines, including petrol, diesel, and hybrid options. The N20 and N26 engines, especially in the 320i and 328i models, are known for timing chain issues that can lead to serious engine damage. Additionally, the oil filter housing gasket is prone to leaking, which can result in oil loss and potential engine damage if not addressed. Checking for oil leaks during a pre-purchase inspection is essential.

BMW 3 Series recall record

66 recalls have been issued for the BMW 3 Series, between 1992 and 2026.

  1. Replace the Engine Starter Motor

    R/2026/054

    Issued 2 March 2026

    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.

    Remedy: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.
