Expert verdict

Tyres: 1.8× the national share

Tyres make up 35.2% of everything recorded on the 2013 BMW M135, against 19.8% nationally — 15.4 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.

Before your test

Three checks worth doing on a 2013 M135

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.

  1. Check the exhaust and emissions 3.1% of tests

    “catalyst emissions carbon monoxide content after 2nd fast idle exceeds default limits”

    Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

  2. Check the tyre tread 3.1% of tests

    “tread depth below requirements of 1.6mm”

    Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.

  3. Check the lights 1.5% of tests

    “headlamp aim too low”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What it costs to get a 2013 M135 through its MOT

Across the 10 items that are recorded most often on this model, the average repair comes to £49–£157 — and 0% of those repairs are parts that cost under £30.

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.
