2006 Renault Ll29 100 — MOT failures & pass rate
The 2006 Renault Ll29 100 passed 68.3% of its 553 recorded MOT tests. All cars of a similar age fail 27.3% of the time, so this is 4.4pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 23.3% of tests against 16.1% for the next-worst category.
At component level the recurring items are ball joint, headlamp aim and position lamp — ball joint alone was recorded 52 times.
A 150k+ example is materially riskier than a 60-90k one: 32.5% versus 16.7%.
Brakes is the most common advisory, noted on 35.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 32.6% in 2021 to 27.9% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2006 Ll29 100
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 23.3% of tests. Start there.
- Lighting & signalling (23.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (16.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (15.9% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
