About the BMW 545
The BMW 545 was MOT tested 515 times in 2024 (DVSA data, retests included) across 3 model years (2003 to 2005), with an average pass rate of 80%. That's close to the average of 82% across all models in our data. Our records list petrol versions.
Best and Worst Years
Of the years with at least 100 tests, the 2005 model has the highest pass rate at 84% from 112 tests. The 2004 model has the lowest at 76%. The 8 point gap means pass rates vary somewhat between years, but no year is dramatically different. Newer cars usually pass more often simply because they are younger.
Mileage Across Years
The oldest model in our data (2003) averages 118,392 miles, while the newest (2005) averages 123,037 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
Compared to the BMW brand average of 88%, the 545 is 8 points lower, placing it among the less reliable BMW models.
Estimated Running Costs
Based on 7,400 miles/year, average pump prices of 174.57p petrol and 199.33p diesel (GOV.UK weekly road fuel prices, week of 19 October 2026), and MOT pass rate data. Insurance not included.
