Audi Q5 2014: reliability & common MOT faults

In 2025, 80 in every 100 first MOTs on a 2014 Audi Q5 were passes. Most common reason for a fail: Suspension arm pins and bushes (front).

Summary

The 2014 Audi Q5 follows the pattern of the model years either side.

  2. Drive shaft joints and boots (front)14 in every 100 failed tests
  3. Headlight aim9 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 2014 Audi Q5 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. 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 (rear), 36 times as often as on similar cars.

Figures below are measured across the 1,675 of 1,676 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 (rear)

Failed on 47 first tests36 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.

Suspension

One fault: suspension arm pins and bushes (front), 3.3 times as often as on similar cars.

Suspension arm pins and bushes (front)

Failed on 253 first tests3.3 times as often as similar carsLikely evidence

What it means

Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 427 first tests, 3.2 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.

Body and structure

Two faults. The strongest is the drive shaft joints and boots (front): 3.2 times as often as on similar cars.

Drive shaft joints and boots (front)

Failed on 240 first tests3.2 times as often as similar carsLikely evidence

What it means

A constant velocity boot that is only severely deteriorated is Minor. It is Major once it is missing, split or insecure so that it no longer prevents the ingress of dirt. A transmission joint excessively worn is Major, and graded Dangerous when it is so worn it is likely to fail.

Exhaust system

Failed on 63 first tests2.2 times as often as similar carsPossible evidence

What it means

Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.

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

Noise, emissions and leaks

One fault: diesel engine warning light, 2.9 times as often as on similar cars.

Diesel engine warning light

Failed on 122 first tests2.9 times as often as similar carsPossible evidence

What it means

An engine malfunction indicator lamp that is illuminated to show a malfunction is graded Major on a diesel, but only on the diesels the test covers, which depends on the vehicle type and when it was first used. DVSA lists it under exhaust emissions for compression ignition engines, and the detail line for the row also names an inoperative lamp.

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 sub-frame (rear)

Noted on 83 first tests2.5 times as often as similar carsElevated evidence

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.

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

First-attempt pass 79.7% of 8,263 first tests (2025): only cars that passed first time count. Official-style pass 82.8%: cars fixed at the test station also count as a pass. The 3 fixed and the 17 not fixed make the 20 in every 100 that did not pass first time.

Petrol and diesel

First testsTypical mileagePassed first time, as testedPassed first time, same mileage
Diesel7,59897,511 miles8080

Figures are in every 100 first tests. Cars with more miles usually fail more often, so the same-mileage figure gives every fuel the mileage mix of all the cars in this year.

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 2014 Audi Q5 follows the pattern of the model years either side. Its main cause of failure was Suspension arm pins and bushes (front), about 15 in every 100 failed tests. In 2025, 79.7% of 8,263 first MOTs on the 2014 Audi Q5 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 82.8%. Among 1,676 failed first-attempt MOT tests (test year 2025), Headlight levelling device (rear) appears more often than on similar cars (2.8% of those tests; 47 observed failures; about 36× 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 2014 Audi Q5 at the first attempt were Suspension arm pins and bushes (front) (15.1%), Drive shaft joints and boots (front) (14.3%) and Headlight aim (8.8%), 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 (rear) (2.8% of those tests; 47 observed failures; about 36× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Headlight levelling device (rear) shows up more often than on similar cars (2.8% of those tests; 47 observed failures; about 36× 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 2014 Audi Q5 include Headlight levelling device (rear), Suspension arm pins and bushes (front), Drive shaft joints and boots (front). 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 2014 Audi Q5 (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.
