  2. Suspension arm ball joint (front)14 in every 100 failed tests
  3. Suspension arm pins and bushes (front)10 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 2003 Volkswagen Passat 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 other passenger door condition (rear): 4.5 times as often as on similar cars.

Figures below are measured across the 831 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

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.

Other passenger door condition (rear)

Failed on 29 first tests4.5 times as often as similar carsPossible evidence

What it means

A lack of door handles is not a defect where it comes from the original design or a specialist modification, provided the door latches securely closed and opens using a control such as a button or a fob. Hinges, catches and pillars are rejected for deterioration only if the doors stop working as intended. A hinged door likely to open inadvertently or not remain closed is graded Dangerous.

Drive shaft joints and boots (front)

Failed on 169 first tests2.9 times as often as similar carsPossible 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.

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

Suspension

Two faults. The strongest is the anti-roll bar linkage pins and bushes (front): 3.6 times as often as on similar cars.

Anti-roll bar linkage pins and bushes (front)

Failed on 32 first tests3.6 times as often as similar carsLikely evidence

What it means

Excessive wear in an anti-roll bar linkage pin or bush is Major. If the pin or bush is likely to become detached, it is graded Dangerous. The wording is DVSA's general one for a suspension pin, bush or joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 60 first tests, 4.8 times as often as on similar cars.

Suspension arm pins and bushes (front)

Failed on 81 first tests2.2 times as often as similar carsPossible 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 158 first tests, 2.3 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.

Noise, emissions and leaks

One fault: diesel emissions test (pre-reg turbo rules before 01/07/2008), 2.6 times as often as on similar cars.

Diesel emissions test (pre-reg turbo rules before 01/07/2008)

Failed on 52 first tests2.6 times as often as similar carsPossible evidence

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

Brakes

One wear pattern: brake discs (rear), 2.4 times as often as on similar cars.

Brake discs (rear)

Failed on 25 first tests2.4 times as often as similar carsWear pattern

What it means

A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 129 first tests, 2.0 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.

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.

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.

FAQs

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

The 2003 Volkswagen Passat follows the pattern of the model years either side. Its main cause of failure was Drive shaft joints and boots (front), about 20 in every 100 failed tests. In 2025, 58.6% of 2,009 first MOTs on the 2003 Volkswagen Passat passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 66.6%. Among 831 failed first-attempt MOT tests (test year 2025), Other passenger door condition (rear) appears more often than on similar cars (3.5% of those tests; 29 observed failures; about 4.5× 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 2003 Volkswagen Passat at the first attempt were Drive shaft joints and boots (front) (20.3%), Suspension arm ball joint (front) (13.6%) and Suspension arm pins and bushes (front) (9.7%), 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: Other passenger door condition (rear) (3.5% of those tests; 29 observed failures; about 4.5× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Other passenger door condition (rear) shows up more often than on similar cars (3.5% of those tests; 29 observed failures; about 4.5× 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 2003 Volkswagen Passat include Other passenger door condition (rear), Anti-roll bar linkage 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 2003 Volkswagen Passat (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.
