2007 London Taxis Int Tx4 — MOT failures & pass rate
4,704 MOT tests on the 2007 London Taxis Int Tx4 are in this dataset, and 73.2% of them passed. All cars of a similar age fail at 26.6%, so the 2007 Tx4 sits squarely on the average. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (14.9%) and suspension (13.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are pins and bushes, rbt (sp) and headlamp aim — pins and bushes alone was recorded 391 times.
Mileage matters less than usual here: the 2007 Tx4 fails 29.8% of the time in the 0-30k band and 27.3% at 150k+, a spread of only 2.5 points.
Advisories point at the next bill rather than this one: suspension was flagged on 23.3% of tests without failing them.

What to check before buying a 2007 Tx4
On a 2007 Tx4, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.9% of tests. Check these areas before you commit.
- Lighting & signalling (14.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (13.4% 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 (13.1% 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.
