The 2013 BMW 123 MOT pass rate is 75.5% of its MOT tests — 3.1 points behind what its age and mileage predict. Brakes is the biggest single reason it fails, at 30.0% of what testers record.
Expert verdict
Brakes: 1.4× the national share
Brakes make up 30.0% of everything recorded on the 2013 BMW 123, against 20.9% nationally — 9.1 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Falls short of its own age and mileage. Like-for-like, cars this age and mileage expect about 78.6%; this one manages 75.5% — 3.1 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 16% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the BMW 123 is most common
Across all 123 model years on record (2007–2013): 5,318 BMW 123 cars tested in a recordable postcode area, across 11,978 tests. Birmingham (B) has the most, with 203 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most BMW 123 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2013 123
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2013 123
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the shock absorbers 5.8% of tests
“shock absorbers has a serious fluid leak”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
-
Check the windscreen 5.0% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the brake pipes 4.3% of tests
“flexible brake hoses slightly twisted”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 23.0% | £45–95 |
| Rigid brake pipes excessively corroded Brakes | Advisory | 11.5% | £80–180 |
| Shock absorbers has a serious fluid leak Suspension | Advisory | 11.5% | £30–75 |
