Top Recorded Microcar Mgo DVSA MOT Test Statistics & Defect Descriptions

The descriptions below are the exact DVSA failure strings testers recorded most often for the Microcar Mgo, each with how many of the model's 391 tests it was noted on.

• "Joints constant velocity boot severely deteriorated" (Minor) — noted on about 17 Microcar Mgo tests, 4.3% of the model's MOT record.
• "Service brake imbalance across an axle" (Major) — noted on about 12 Microcar Mgo tests, 3.1% of the model's MOT record.
• "Catalyst emissions Lambda reading after 2nd fast idle outside specified limits" (Major) — noted on about 10 Microcar Mgo tests, 2.6% of the model's MOT record.
• "Steering rack gaiter damaged or deteriorated, but preventing the ingress of dirt" (Minor) — noted on about 9 Microcar Mgo tests, 2.3% of the model's MOT record.
• "Wheel bearings rough when rotated" (Major) — noted on about 8 Microcar Mgo tests, 2.0% of the model's MOT record.

Best and Worst Microcar Mgo Model Years by Pass Rate

The strongest Microcar Mgo model year on record is 2011 (81.8% across 121 tests), and the weakest is 2012 (75.0%). The gap between them is 6.8 points. Years with fewer than 50 recorded tests are excluded, so these are the years with enough MOT history to mean something.

Microcar Mgo reliability is declining in the DVSA data — the pass rate moves about 1.1 points a year across the most recent model years shown above.

Newest model year first. Only years with at least 50 recorded tests are listed.

Pre-MOT Inspection Checklist for Microcar Mgo Owners

These checks follow this Microcar Mgo's own most-recorded failure strings, starting with what a tester is most likely to flag on a Microcar Mgo.

• the exhaust and emissions — “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

  Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

• the steering — “steering rack gaiter damaged or deteriorated,”

  With the wheels straight, rock the steering wheel gently with the engine off — more than about an inch of free play before the wheels move is worth investigating. Split rack gaiters are cheap to replace and commonly recorded.

• the wheel bearings — “wheel bearings rough when rotated”

  Listen for a hum that rises and falls with speed and changes when you load one side in a bend. A noisy bearing is an easy pre-test diagnosis and an awkward surprise at the test station.
