Known faults, from the test record

Skoda Scala common problems

What fails on the Skoda Scala at MOT, which parts are behind it, and how each model year compares. From 10,179 DVSA test records.

Data updated

Quick answer

The Skoda Scala's most common MOT problems are tyres, brake pads and shoes, brake discs, recorded in 53.0%, 29.5% and 22.8% of failed tests respectively. By model year, 2022 cars pass most often (88.5%) and 2019 cars least (81.8%), though most of that gap is age. Every figure here is what testers recorded, not what owners reported.

A “common problems” list is usually a forum thread: whoever had the worst day writes the longest post. This one is built the other way, from every Skoda Scala that took an MOT last year and what the tester wrote down. It cannot see breakdowns, electrical gremlins or a gearbox that hunts, because the test does not check those. What it can see, it sees across 10,179 cars.

By component

What wears out on a Scala

Failure items grouped by the part behind them, with the share of failed Skoda Scala tests recording each. A part can carry several DVSA wordings; they are listed beneath. One failed test often lists several items, so shares do not sum to 100%.

  1. 1.Tyres

    53.0% of failed tests

    Tread wears with every mile and sidewalls age and take kerb damage; the legal minimum is 1.6 mm across the central three-quarters.

    • “A tyre seriously damaged” — explained16.9%
    • “Tyre tread depth not in accordance with the requirements” — explained11.4%
    • “A tyre seriously damaged” — explained7.5%
    • “A tyre seriously damaged” — explained7.1%

    Across all cars, tyres failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long tyres last

  2. 2.Brake pads and shoes

    29.5% of failed tests

    Friction material wears with use; the MOT limit is 1.5 mm and a pad that thin is close to metal on metal.

    • “a brake lining or pad worn below 1.5mm” — explained27.6%
    • “Brake lining or pad worn down to wear indicator” — explained1.5%
    • “Brake lining or pad missing or incorrectly mounted” — explained0.4%

    Across all cars, brake pads and shoes failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long brake pads and shoes last

  3. 3.Brake discs

    22.8% of failed tests

    Discs thin with each pad set and pit or corrode when lightly used; failure is for significant wear, fracture or insecurity, advisory for surface condition.

    • “Brake disc or drum significantly and obviously worn” — explained10.2%
    • “Excessive fluctuation in brake effort through each wheel revolution.” — explained6.7%
    • “Brake disc or drum excessively weakened, insecure or fractured” — explained5.1%
    • “Excessive fluctuation in brake effort through each wheel revolution” — explained0.8%

    Across all cars, brake discs failures climb 3-fold between three and fifteen years, peaking at 12–14 years. How long brake discs last

  4. 4.Steering rack and column

    12.5% of failed tests

    Rack gaiters split and let dirt in; the rack itself and the column are rarely the failing part.

    • “Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc” — explained10.9%
    • “Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc” — explained1.6%

  5. 5.Wiper blades and washers

    8.3% of failed tests

    Rubber blades harden and split within a year or two; washer jets block and pumps fail.

    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained4.1%
    • “Wiper blade missing or obviously not clearing the windscreen” — explained2.8%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained1.4%

    Across all cars, wiper blades and washers failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long wiper blades and washers last

  6. 6.Bulbs and lamps

    4.6% of failed tests

    Filament bulbs simply expire; the cheapest and most avoidable failure on the test, and one of the most recorded.

    • “An obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained4.2%
    • “An obligatory rear fog lamp missing, or a front or rear fog lamp inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained0.4%

    Across all cars, bulbs and lamps failures climb 15-fold between three and fifteen years, peaking at 15+ years. How long bulbs and lamps last

  7. 7.Engine management

    4.4% of failed tests

    The MIL lamp lit is a failure in itself, whatever the stored code; the fault codes section explains what lies behind it.

    • “Engine MIL illuminated indicating a malfunction” — explained4.4%

  8. 8.Headlamp aim

    2.6% of failed tests

    Aim drifts with sagging suspension, a knocked lamp or a botched bulb change; adjustment, not a part.

    • “The aim of a headlamp is not within limits laid down in the requirements” — explained1.5%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained1.1%

By registration year

Scala problems by year

MOT pass rate for Skoda Scala cars by the year they were first registered, from years with at least 1,000 tests. Every car in a row is the same age, so the rate is raw. Neighbouring years differ by a year of wear — a step of a point or two is age. The step at 2020, up 5.5 points, is larger than wear explains and most likely marks a change in the cars themselves.

201982%
202087%+5.5
202188%+0.4
202289%+0.8

Last column: change on the previous year, in points. Years registered within the last three years have not yet been tested and are not shown.

Common questions

What are the most common problems with a Skoda Scala?
Going by what fails the MOT, tyres (recorded in 53.0% of failed tests), brake pads and shoes (recorded in 29.5% of failed tests), and brake discs (recorded in 22.8% of failed tests). These are the items testers actually record across 10,179 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Skoda Scala year is the most reliable?
By MOT pass rate, Skoda Scala cars registered in 2022 do best at 88.5% and 2019 cars do worst at 81.8%. Most of that ordering is simply age — newer cars pass more — so read the year table for steps larger than a couple of points between neighbouring years; those mark a change in the cars rather than the calendar. The largest such step is at 2020, up 5.5 points on 2019.
Is the Skoda Scala reliable?
The Skoda Scala passes 86.9% of MOTs unadjusted; its fleet is too narrow in age or mileage for a fair national comparison. An MOT measures roadworthiness on the day rather than breakdowns or running costs, so this is a reliability measure in the narrow sense: how often the car meets the legal standard, and what stops it.
What should I check when buying a used Skoda Scala?
Start with what fails most: tyres, brake pads and shoes, brake discs. Then read the car's own MOT history for advisories carried year to year without repair — the model tells you what to expect, the history tells you whether this owner dealt with it.
