MOT advisory “Condition slightly distorted” — meaning and what to do

Last updated · OBDCode UK editorial

In plain English: the tester noted a road-wheels item that was not a fail on that MOT. Fix soon.

This advisory means the tester found condition that was slightly distorted — not judged bad enough to fail that recorded test, but noted for attention. It was recorded 495,595 times on UK Class 4 MOT certificates in 2025 (about #25 in this dataset).

Can you drive with this?

Drive with care. You can usually keep driving carefully for now. Watch for worsening wear, noise, vibration, or warning lights, and book a check soon — especially before any long journey.

What the tester saw

MOT testers work from the DVSA inspection manual. For this item the manual wording is “A wheel badly distorted or wear between wheel and hub at spigot mounting”. In plain English: the tester judged that wear or deterioration on the condition had not gone far enough to reject at that test. That is why it was recorded as an advisory rather than a failure. It is not a statement about the vehicle’s condition or legal status today.

If it worsens to the manual fail wording above, DVSA would class that defect as Major. That grade describes the fail threshold, not the recorded advisory.

Do you need to fix it?

An advisory did not affect that test’s result. It is the tester telling you what is likely to need attention, and how soon depends on the item.

  • Fix soon. A slightly distorted wheel should be inspected within a few weeks — vibration can worsen hub wear. Do not ignore steering shake; stop if the wheel wobbles badly, you see cracks, or the tyre beads unevenly.
  • Can you DIY? We do not publish DIY repair or strip-down steps for this advisory. External look-over only; leave structural, brake hydraulic, fuel, steering, or restraint work to a qualified garage.
  • Buying a used car? Repeated advisories for the same item across several years of MOT history mean the owner has been ignoring it. Check the car’s full record with our free MOT history check.

What happened to other cars with this advisory

Of the 163,219 cars that passed their 2024 MOT with this advisory, 0.52% (95% CI 0.5–0.6) failed on that same item the following year — 30 times the rate for cars without it.

These figures are a statistical association from the national MOT extracts. They are not a prediction about this car, and we have not inspected it.

Their rate of failing a 2025 MOT for any reason was 26.5% (95% CI 26.3–26.7), against 18.2% (95% CI 18.1–18.2) for cars that passed without this advisory.

The median car in this cohort was 11.0 years old with 72,261 miles at the 2024 test.

A robustness re-run on the 78,318 cars tested in January–June 2024 only — so the next annual test almost always falls inside 2025 — found a same-item fail rate of 0.53% (95% CI 0.5–0.6) and a not-retested gap of +1.1 points. A December 2024 test may not be due until 2026, which can make a car look as if it vanished; the first-half window removes most of that censoring.

Same wording as a fail

Of the 11,428 cars that failed on this line in 2024, 0.90% (95% CI 0.7–1.1) failed on it again in 2025 — 33 times the rate for cars that did not fail on this item, and 18.9% (95% CI 18.2–19.7) of those 11,428 cars that failed were not tested again. Did this failure stay fixed?
