Expert verdict
Body & chassis: 2.5× the national share
Body & chassis accounts for 14.0% of everything recorded on the 2005 Piaggio Porter, against 5.6% nationally — 8.4 points above. Suspension is still the single largest share at 19.8%, but at 21.0% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.
- Failures here tend to be cheap ones. 71% of the repairs this model fails on cost under £30 in parts. The pass rate matters less than what a bad afternoon at the test centre actually costs you.
- Based on a small sample. 151 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2005 Porter
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 2005 Porter
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 12.6% of tests
“headlamp reflector slightly defective”
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 exhaust and emissions 6.0% of tests
“exhaust system has a major leak of exhaust gases”
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 corrosion 5.3% of tests
“component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength”
Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
