Advisories to look for in a Vauxhall Astra's MOT history
An advisory is a tester's warning that something is wearing but has not failed yet. These are the ones written most often on the Vauxhall Astra, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.
- Tread depth: worn close to legal limit/worn on edge277.5
- Tyres: slightly damaged/cracking or perishing181.0
- Brake discs: worn, pitted or scored, but not seriously weakened167.2
- Engine oil leaks: leak, but not excessive152.9
- Brake pads: wearing thin113.9
- Coil spring: corroded91.1
Checking a used Vauxhall Astra before you buy
Against cars of the same age, the Vauxhall Astra fails more often than average on brakes, tyres and engine, emissions and leaks. Start there.
Brakes
Look through the wheel spokes at the discs for a deep lip or scoring, check the handbrake holds the car on a slope, and feel for a pull to one side when braking hard.
Tyres
Check the tread across the full width of every tyre, inner edge included. Uneven wear points to worn suspension or out of line steering geometry.
Engine, emissions and leaks
Start the car from cold and watch the exhaust for smoke, look underneath for oil or fuel leaks, and make sure the engine warning light comes on with the ignition and goes out once the engine runs.
Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

How these figures are calculated
Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Vauxhall Astra cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
