BMW 5 Series G30 (2017–2025): what fails at MOT
Across 48,429 MOT tests of the BMW 5 Series G30 (2017–2025) in the DfT's 2023 MOT data (initial tests, retests excluded), 11.9% failed — about 1 in 8. The parts that fail most are tyres (7.1% of tests), lights and electrics (1.5%), wipers, windscreen and mirrors (1.0%), exhaust, fuel and emissions (0.9%) and wheels (0.9%).
Allowing for age and mileage, the 5 Series G30 has 31% fewer MOT failures than the average car of the same age and mileage. That puts it last of the three BMW 5 Series generations on MOT results; the 5 Series F10 (2010–2017) does best.
The MOT checks safety and emissions items — brakes, suspension, steering, lights, tyres, body structure and exhaust emissions. It does not test engines, gearboxes or most electronics, so those faults only show up here when they cause an emissions failure or a leak.
