Vauxhall Astravan 2005: reliability & common MOT faults

In 2025, 53 in every 100 first MOTs on a 2005 Vauxhall Astravan were passes. Most common reason for a fail: Handbrake efficiency below minimum (roller test).

Summary

With 995 first tests, there are too few to say whether the 2005 Vauxhall Astravan differs from the model years either side.

  2. Headlight aim14 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 2005 Vauxhall Astravan 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.

Noise, emissions and leaks

Two faults. The strongest is the diesel engine warning light: 7.7 times as often as on similar cars.

Figures below are measured across the 429 of 464 failed first attempts (92.5%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like. 7.5% 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.

Diesel engine warning light

Failed on 31 first tests7.7 times as often as similar carsLikely 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.

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

Failed on 34 first tests3.2 times as often as similar carsLikely evidence

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

Brakes

Two faults. The strongest is the rigid brake pipes (front): 4.2 times as often as on similar cars.

Rigid brake pipes (front)

Failed on 34 first tests4.2 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 67 first tests, 2.6 times as often as on similar cars.

Rigid brake pipes (rear)

Failed on 42 first tests2.7 times as often as similar carsPossible 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 105 first tests, 2.6 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

One fault: exhaust system (rear), 2.8 times as often as on similar cars.

Exhaust system (rear)

Failed on 28 first tests2.8 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.

Suspension

Three faults. The strongest is the shock absorbers (front): 2.4 times as often as on similar cars.

Shock absorbers (front)

Failed on 21 first tests2.4 times as often as similar carsPossible evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 58 first tests, 3.5 times as often as on similar cars.

Coil spring (front)

Failed on 34 first tests2.3 times as often as similar carsPossible evidence

What it means

A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.

Shock absorbers (rear)

Failed on 28 first tests2.3 times as often as similar carsPossible evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

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

Visibility

One fault: windscreen wipers (front), 2.2 times as often as on similar cars.

Windscreen wipers (front)

Failed on 29 first tests2.2 times as often as similar carsPossible evidence

What it means

Only a clearly damaged or worn windscreen wiper needs to be rejected. A wiper that is missing or not working is graded Major, and so is a blade that is missing or obviously not clearing the windscreen. A defective blade is graded Minor.

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.

MOT pass rates

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

Passed first time
53in every 100

FAQs

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

With 995 first tests, there are too few to say whether the 2005 Vauxhall Astravan differs from the model years either side. Its main cause of failure was Handbrake efficiency below minimum (roller test), about 17 in every 100 failed tests. In 2025, 53.4% of 995 first MOTs on the 2005 Vauxhall Astravan passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 60.8%. Among 464 failed first-attempt MOT tests (test year 2025), Diesel engine warning light appears more often than on similar cars (7.2% of those tests; 31 observed failures; about 7.7× 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 2005 Vauxhall Astravan at the first attempt were Handbrake efficiency below minimum (roller test) (16.8%) and Headlight aim (14.5%), 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: Diesel engine warning light (7.2% of those tests; 31 observed failures; about 7.7× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Diesel engine warning light shows up more often than on similar cars (7.2% of those tests; 31 observed failures; about 7.7× 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 2005 Vauxhall Astravan include Diesel engine warning light, Rigid brake pipes (front), Exhaust system (rear). 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 2005 Vauxhall Astravan (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.
