Peugeot 306 common problems and MOT failures
What goes wrong on a used Peugeot 306, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 12,373 MOTs done during 2023–2025), and what to check before you buy one.
The 1993 Peugeot 306
Too few Peugeot 306 cars first registered in 1993 had an MOT during 2025 for reliable MOT figures. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the Peugeot 306 as a whole.
What to check on a 1993 car
- MOT history
Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.
- Service history
Look for regular servicing and receipts for big jobs like a cambelt or clutch.
- Finance and write-offs
MOT records don’t show outstanding finance or insurance write-offs. A history check does.
- Test drive
Listen for knocks over bumps, check every warning light goes out, and make sure the gears and brakes feel right.
Other years
Most years have their own guide. The year is when the car was first registered (it’s on the logbook, or check the reg below).
What usually goes wrong with a Peugeot 306?
Known faults reported by owners, mechanics and UK buying guides, in our own words. Most apply to certain years or engines only, so check which the car has.
- Cars registered in 2022 · 1.0 and 1.2 PureTech petrol
Timing belt that runs in oil (PureTech petrol)
The 1.0 and 1.2 PureTech petrol engines use a timing belt that runs in the engine oil (a “wet belt”). It can break down early and shed rubber that blocks the oil supply, which can wreck the engine. Some also burn too much oil. Stellantis now covers earlier engines for belt and oil-burning problems for up to 10 years or 112,000 miles, as long as the car has been serviced on schedule.
At the viewing: Ask for a full service history showing the right oil, and when the belt was last checked or changed. Check the oil level on the dipstick, and that no oil-pressure or engine warning light stays on.

Questions to ask the seller before buying a Peugeot 306
Ask before you travel to see it. A seller who knows the car will have answers, and receipts.
- When was the timing belt last checked or changed, and has it had the right oil at every service? Is the car still within Stellantis’ extended PureTech cover?
- Any recent work on the steering rack? (Flagged at MOT 3.9× as often on the Peugeot 306 as on other cars the same age.)
- Any recent work on the side repeaters? (Flagged at MOT 3.7× as often on the Peugeot 306 as on other cars the same age.)
- Any recent work on the anti-roll bar link joints? (Flagged at MOT 3.4× as often on the Peugeot 306 as on other cars the same age.)
- Can I see the service history and receipts for any big jobs?
