1999 Mercedes-Benz Sprinter — MOT failures & pass rate
1,441 MOT tests on the 1999 Mercedes-Benz Sprinter are in this dataset, and 73.0% of them passed. That is 2.6 percentage points better than vans of a similar age, which fail at 29.6%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 19.9% of all tests — 3.7 points clear of brakes, so it is the first thing to check.
At component level the recurring items are component mounting prescribed areas, chassis condition and service brake performance — component mounting prescribed areas alone was recorded 143 times.
Mileage matters less than usual here: the 1999 Sprinter fails 32.4% of the time in the 0-30k band and 30.7% at 150k+, a spread of only 1.7 points.
Advisories point at the next bill rather than this one: brakes was flagged on 39.4% of tests without failing them.
The trend is improving — the fail rate fell from 29.8% in 2021 to 23.8% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 1999 Sprinter
On a 1999 Sprinter, lighting & signalling is what the MOT record says goes wrong most — it appeared in 19.9% of tests. Check these areas before you commit.
- Lighting & signalling (19.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (16.2% 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.
- Suspension (10.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
