There are 3 BMW 4 Series currently available on Motoring.Today, with prices starting from £12,777, or a representative monthly payment of £294. Based on 1,277 actual DVSA MOT tests across the UK, the model achieves an 84.02% pass rate. This figure reflects the condition of cars presented for testing, not necessarily the car's lifetime dependability, as failures tend to accumulate with age and insufficient maintenance rather than being indicative of the badge itself. The most frequent reasons for MOT failure for this model offer valuable insight for potential buyers. "Tyres" account for a significant 35% of all failures, indicating that buyers should meticulously inspect tyre tread depth, condition, and ensure pressures are correct. Other significant failure categories include "Lighting & electrical" (18%) and "Brakes" (15%). These typically point to common wear-and-tear items such as blown bulbs, faulty wiring, or worn brake pads and discs. Before committing to a purchase, it is highly advisable to perform a thorough check of all lights, indicators, and interior electrical components, and to critically assess the tyres. A pre-purchase inspection by a qualified mechanic can also help identify any issues with the braking system or other mechanical components that might lead to an MOT failure down the line.
