MOT advisories
What MOT advisories really mean
Advisories are not failures, but they tell you what is wearing. Learn which ones matter, which to negotiate on, and when to walk away.
Understanding advisories
What is an MOT advisory?
An advisory is a note from the MOT tester about something that is not bad enough to fail but may need attention soon. The car still passes, but you are warned about developing issues.
Not a failure
Advisories do not stop the car passing. They are a heads-up, not a showstopper.
Future problems
Many advisories become failures if left unaddressed. Worn brakes today, failed brakes next year.
Negotiation tool
Use advisories to negotiate the price. The seller knows work is needed.
Maintenance clues
Recurring advisories suggest the owner skipped servicing or repairs.
Budgeting help
Advisories let you estimate upcoming repair costs before buying.
Severity varies
Some advisories are trivial. Others (corrosion, brakes) need prompt action.
Common advisories
Advisories you will see often
These are some of the most common MOT advisories and what they mean for you as a buyer.
Brake pads wearing thin
Common and expected. Budget £100-300 for replacement depending on the car.
Tyres approaching legal limit
Tyres with 2-3mm tread may pass but need replacing soon. £50-200 per tyre.
Corrosion on body or chassis
Minor surface rust is cosmetic. Structural corrosion is serious and expensive.
Suspension components worn
Bushes, drop links, and shocks wear over time. Can be £100-500+ to fix.
Exhaust slightly blowing
Small leaks may pass but will worsen. Repair or replacement needed eventually.
Windscreen damage
Small chips in the swept area are advisory. Larger cracks in the driver view fail.
Watch out
Advisories that should worry you
Not all advisories are equal. These ones deserve extra scrutiny before you buy.
Structural corrosion
Rust on load-bearing parts (chassis, subframe, sills) can make the car uneconomical to repair.
Brake disc wear
Discs are more expensive than pads. Worn discs often need replacing with the pads.
Steering or suspension play
Play in steering components affects handling and can become a safety issue.
Oil leaks
Minor leaks may be noted as advisory. Investigate the source - some are cheap, others expensive.
