BMW 630: MOT pass rate and reliability data

The BMW 630 fails its first MOT more often than the average UK car, by 1.9 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 2,856 individual BMW 630 tests. Nothing here is an estimate or a survey.

First-time pass rate74.8%
UK national average76.7%

Reliability rank1,625 of 2,005 models

What this means if you are buying one

A 74.8% first-time pass rate means roughly 25 in every 100 BMW 630s presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average BMW 630 tested had covered 111,275 miles and was built around 2007.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. On a BMW 630 bought as a repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

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 630 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 630s actually sold for at UK salvage auction.

BMW 630 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 630 year:
