BMW X5 2006: reliability & common MOT faults

In 2025, 61 in every 100 first MOTs on a 2006 BMW X5 were passes. Most common reason for a fail: Suspension arm ball joint (front).

Summary

A 2006 BMW X5 passed first time about 4 in every 100 less often than the average of the 2005 and 2007 model years.

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 2006 BMW X5 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.

Body and structure

Two faults. The strongest is the driver's door condition (front): 35 times as often as on similar cars.

Figures below are measured across the 873 of 892 failed first attempts (97.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like. 2.1% of failures are excluded because no mileage was recorded, so treat these shares as indicative for this model year.

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.

Driver's door condition (front)

Failed on 37 first tests35 times as often as similar carsLikely evidence

What it means

Doors without handles by original design or specialist modification are not a defect so long as the door latches securely closed and can still be opened using the relevant control, such as a button or a fob. A door likely to open inadvertently or not remain closed is Major on a sliding door and graded Dangerous on a hinged one.

Front passenger door condition

Failed on 24 first tests15 times as often as similar carsPossible evidence

What it means

A front passenger door that will not open from inside or outside, or does not latch securely closed, is Major. The opening defects do not apply on goods vehicles modified to carry high value cargoes, such as armoured security vehicles, or where the aperture was permanently filled as a specialised customisation with no obvious gaps. A hinged door likely to open inadvertently is Dangerous, the sliding door version Major.

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

Suspension

Two faults. The strongest is the suspension arm ball joint (rear): 19 times as often as on similar cars.

Suspension arm ball joint (rear)

Failed on 21 first tests19 times as often as similar carsPossible evidence

What it means

A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and likely to become detached is graded Dangerous.

Suspension arm ball joint (front)

Failed on 164 first tests2.8 times as often as similar carsPossible evidence

What it means

A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and likely to become detached is graded Dangerous.

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

Brakes

Two faults. The strongest is the handbrake efficiency below minimum (decelerometer test): 16 times as often as on similar cars.

Handbrake efficiency below minimum (decelerometer test)

Failed on 73 first tests16 times as often as similar carsLikely evidence

What it means

A parking brake with efficiency below the minimum requirement is graded Major, and efficiency less than half of the required value is graded Dangerous. This check applies only to vehicles whose parking brake has not already been tested as the secondary brake.

Rigid brake pipes (front)

Failed on 49 first tests3.2 times as often as similar carsLikely evidence

What it means

Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 156 first tests, 3.3 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Seat belts and restraints

One fault: seat belt condition (rear), 2.3 times as often as on similar cars.

Seat belt condition (rear)

Failed on 23 first tests2.3 times as often as similar carsPossible evidence

What it means

Any sign of overstretching is a deficiency, and so is a cut anywhere on a child seat belt. On other belts the size of a cut decides it, with a stricter limit at the webbing edge than away from it. Webbing significantly stretched or weakened has rows in both Major and Dangerous grades.

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

Tyres

One wear pattern: tyre condition (rear), 2.2 times as often as on similar cars.

Tyre condition (rear)

Failed on 99 first tests2.2 times as often as similar carsWear pattern

What it means

Exposed or damaged ply or cords are graded Dangerous. A cut in excess of the requirements and deep enough to reach the ply or cords is Major, and testers may open the cut with a blunt instrument to check its depth. A tyre contacting the vehicle through flexing or suspension movement is not a defect; fouling fails only at the time of test.

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. Advisories for the faults above are shown with those faults.

Suspension arm pins and bushes (rear)

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

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.

A 2006 BMW X5 passed first time about 4 in every 100 less often than the average of the 2005 and 2007 model years. In 2025, 61.4% of 2,310 first MOTs on the 2006 BMW X5 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 67.1%. Among 892 failed first-attempt MOT tests (test year 2025), Driver's door condition (front) appears more often than on similar cars (4.2% of those tests; 37 observed failures; about 35× 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 2006 BMW X5 at the first attempt were Suspension arm ball joint (front) (18.8%), Handbrake efficiency below minimum (roller test) (18.1%) and Tyre condition (rear) (11.3%), 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: Driver's door condition (front) (4.2% of those tests; 37 observed failures; about 35× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Driver's door condition (front) shows up more often than on similar cars (4.2% of those tests; 37 observed failures; about 35× 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 2006 BMW X5 include Driver's door condition (front), Suspension arm ball joint (rear), Handbrake efficiency below minimum (decelerometer test). 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 2006 BMW X5 (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.
