The 2006 Audi A4 MOT pass rate is 75.5% of its MOT tests — 3.0 points ahead of what its age and mileage predict. Suspension is the biggest single reason it fails, at 26.8% of what testers record.
Expert verdict
Suspension: 1.3× the national share
Suspension accounts for 26.8% of everything recorded on the 2006 Audi A4, against 21.0% nationally — 5.8 points above. Ask for the front and rear suspension to be checked on a ramp before you buy — worn bushes and broken springs are cheap to look at and expensive to discover at test time.
- Beats its own age and mileage. Once you allow for how old and how far these cars have been driven, the expected pass rate is 72.5% and this one manages 75.5% — 3.0 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 20% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

Where the Audi A4 is most common
Across all A4 model years on record (2000–2023): 393,657 Audi A4 cars tested in a recordable postcode area, across 888,010 tests. Birmingham (B) has the most, with 14,329 cars tested there. Cars are counted by the postcode area of the MOT station, so this is where they were tested, not necessarily where their owners live.

The twenty areas with the most Audi A4 cars in the record, sorted by car count — sort the columns for a different question. Cars tested at a station whose postcode area could not be resolved are counted in the model's total but in no area, so the shares add up to slightly under 100% even across every area, and an area's cars are a subset of the model's. Pass rate is blank below 30 tests in an area, where a percentage is noise rather than a finding. How this model's pass rate varies by postcode →

What fails a 2006 A4
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2006 A4
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 10.0% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the suspension joints 7.4% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
Check the windscreen 5.7% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2006 A4 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £34–£97 — and 20% of those repairs are parts that cost under £30.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 19.8% | £45–95 |
| Pins and bushes pin or bush excessively worn Suspension | Advisory | 18.4% | £40–150 |
