Expert verdict
Fewer problems with suspension
Suspension is 14.5% of this car’s recorded faults, against 21.0% nationally — the mirror image of the usual story on a car of this age.
- 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 88.6% — 16.1 points ahead of what its age and mileage predict.
- When it fails, it costs. Only 13% 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.

Every Porsche 911 first registered in 2006 is combined here — 3 trim and body variants in total — so the sample is as large as the DVSA data allows.
How does the 2006 Porsche 911 compare?
Cars of this age and mileage average 72.5%, so this figure is 16.1 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 87.6%. The median 2006 Porsche 911 in this dataset had covered 67,463 mi.
Pass rates also shift with the test month: tests recorded October–March passed 88.2% of the time, April–September 88.9%.
The single most recorded failure item is "Windscreen damaged but not adversely affecting driver's view", noted on 2.49% of tests.
- 8,797 recorded tests behind this page.
- 88.6% overall pass rate, 87.6% on a first attempt.
- Across every year of the Porsche 911, the average is 91.0% — best year 2022 (96.6%), worst 2003 (85.5%).

What fails a 2006 911
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 911
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 windscreen 2.5% 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.
-
Check the exhaust and emissions 2.2% of tests
“catalyst emissions Lambda reading after 2nd fast idle outside specified limits”
Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.
-
Check the lights 1.0% 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.
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 911 through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £59–£178 — and 13% 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.

| Rigid brake pipes excessively corroded Brakes | Advisory | 10.8% | £80–180 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 9.8% | £45–95 |
