What usually goes wrong with the BMW 118i F20?
From owners, mechanics and UK buying guides, in our own words. Not every car will have them.
EGR valve leak (diesel)
The EGR valve on diesels can leak and, in rare cases, has caused fires. BMW issued recalls.
Check: Ask a BMW dealer whether the recall work was done. Watch for a strange smell or rough running.
Engine and lights cutting out
An electrical fault could cut the engine and exterior lights. There have been three recalls.
Check: Ask a BMW dealer to confirm the recall work. Flickering lights on the dash can be an early sign.
Propshaft joint
The front propshaft joint can fail and leave the car stranded.
Check: Listen for clunks or vibration from under the middle of the car.
Water getting in
Blocked drains at the base of the windscreen can let water damage the electrics. Lights can mist up inside.
Check: Look for condensation in the lights and damp carpets.
Where this comes from: the DVSA's anonymised results for every MOT test done in Great Britain during 2023–2025, counting each car's main test of the year (not retests). A weak spot needs at least 30 cars flagged and must stay 1.5× the usual rate even at the cautious end of a 95% confidence range. Generation years are approximate: cars registered in a changeover year (*) can be either generation. How we score
