BMW 640: MOT pass rate and reliability data

The BMW 640 passes its MOT first time more often than the average UK car, by 6.4 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 10,004 individual BMW 640 tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate83.1%
UK national average76.7%
Difference+6.4 points
Tests analysed10,004
Average mileage at test76,733 miles
Average year of manufacture2015
Reliability rank1,334 of 2,005 models

What this means if you are buying one

A 83.1% first-time pass rate means roughly 17 in every 100 BMW 640s 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 640 tested had covered 76,733 miles and was built around 2015.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a BMW 640 bought as a 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 640 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 what damaged BMW 640s actually sold for at UK salvage auction.

From 22,331 DVSA-tracked BMW 640 tests, 2024. DVSA testers marked 11.21% of these flagged BMW 640 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 4.97% nationally.

BMW 640 pass rate by model year

Pass rates fall steadily as cars age, so the model year matters as much as the model. First-time pass rate for each BMW 640 year:

Diesel and petrol versions of the same car fail on different things, so the fuel type moves the number:
