BMW 540: MOT pass rate and reliability data

The BMW 540 passes its MOT first time more often than the average UK car, by 0.4 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 702 individual BMW 540 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 77.1% first-time pass rate means roughly 23 in every 100 BMW 540s presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average BMW 540 tested had covered 122,727 miles and was built around 2001.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The BMW 540 sits 0.4 points above the national average, ranked 1,549 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific BMW 540 rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged BMW 540s at UK salvage auction.

From 694 DVSA-tracked BMW 540 tests, 2024. DVSA testers marked 2.78% of these flagged BMW 540 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a BMW 540

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a BMW 540 before it actually fails on it.

1. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 2.7% of tests (20.46x the national rate for this advisory), also fails
2. A flexible brake hose excessively damaged, deteriorated, chafed, twisted or stretched, 6.1% of tests (10.8x the national rate for this advisory)
3. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 30.1% of tests (5.42x the national rate for this advisory)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 6.1% of tests (4.86x the national rate for this advisory)
5. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 6.1% of tests (3.99x the national rate for this advisory)
6. Brake pipe damaged or excessively corroded, 19.7% of tests (3.19x the national rate for this advisory)
7. Lamp emitted colour, position or intensity not in accordance with the requirements, 3.3% of tests (2.42x the national rate for this advisory)
8. A suspension pin, bush or joint excessively worn, 20.9% of tests (1.56x the national rate for this advisory), also fails
