BMW 5 Series 2010: reliability & common MOT faults

In 2025, 73 in every 100 first MOTs on a 2010 BMW 5 Series were passes. Most common reason for a fail: Coil spring (front).

Summary

The 2010 BMW 5 Series follows the pattern of the model years either side.

  2. Individual sidelight or tail light (front)11 in every 100 failed tests
  3. Tyre condition (rear)11 in every 100 failed tests

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2010 BMW 5 Series vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Lamps and electrical

One fault: headlight levelling device, 6.4 times as often as on similar cars.

Figures below are measured across the 1,954 of 1,955 failed first attempts (99.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Headlight levelling device

Failed on 43 first tests6.4 times as often as similar carsLikely evidence

What it means

A headlamp levelling device that is inoperative is graded Major, and so is a manual levelling device that cannot be operated from the driver's seat. Vehicles with high intensity discharge or LED dipped beam headlamps may have a self-levelling system, and if fitted it must work. Where it is not easy to tell, testers give the benefit of the doubt, and motor caravans are not checked.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Tyres

One wear pattern: tyre tread depth (rear), 2.3 times as often as on similar cars.

Tyre tread depth (rear)

Failed on 156 first tests2.3 times as often as similar carsWear pattern

What it means

Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Advisories

Other things testers noted as worn or close to failing, more often than on similar cars.

An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail.

Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
73in every 100
Passed on the first test.

Did not pass, and were not fixed at the test station.

First-attempt pass 73.3% of 7,321 first tests (2025): only cars that passed first time count. Official-style pass 78.0%: cars fixed at the test station also count as a pass. The 5 fixed and the 22 not fixed make the 27 in every 100 that did not pass first time.

If you are buying one

What this year's MOT record means for the decision in front of you.

Mileage makes little difference on a 2010 BMW 5 Series.

Of 2010 BMW 5 Series vehicles with under 100,000 miles, 76 in every 100 passed their 2025 MOT first time. With 170,000 miles or more, 74 in every 100 did.

What to check at your mileage

How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

FAQs

Short answers about how to read this model-year guide.

The 2010 BMW 5 Series follows the pattern of the model years either side. Its main cause of failure was Coil spring (front), about 12 in every 100 failed tests. In 2025, 73.3% of 7,321 first MOTs on the 2010 BMW 5 Series passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 78.0%. Among 1,955 failed first-attempt MOT tests (test year 2025), Headlight levelling device appears more often than on similar cars (2.2% of those tests; 43 observed failures; about 6.4× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2010 BMW 5 Series at the first attempt were Coil spring (front) (11.7%), Individual sidelight or tail light (front) (11.3%) and Tyre condition (rear) (11.0%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Headlight levelling device (2.2% of those tests; 43 observed failures; about 6.4× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Headlight levelling device shows up more often than on similar cars (2.2% of those tests; 43 observed failures; about 6.4× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2010 BMW 5 Series include Headlight levelling device. These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2010 BMW 5 Series (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
