Top Recorded MG Mgf DVSA MOT Test Statistics & Defect Descriptions

The descriptions below are the exact DVSA failure strings testers recorded most often for the MG Mgf, each with how many of the model's 9,884 tests it was noted on.

• "Rbt (sp) efficiency below requirements" (Major) — noted on about 418 MG Mgf tests, 4.2% of the model's MOT record.
• "Catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits" (Major) — noted on about 244 MG Mgf tests, 2.5% of the model's MOT record.
• "Service brake performance efficiency below requirements" (Major) — noted on about 218 MG Mgf tests, 2.2% of the model's MOT record.
• "Component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength" (Major) — noted on about 193 MG Mgf tests, 2.0% of the model's MOT record.
• "Catalyst emissions Lambda reading after 2nd fast idle outside specified limits" (Major) — noted on about 191 MG Mgf tests, 1.9% of the model's MOT record.

Best and Worst MG Mgf Model Years by Pass Rate

The strongest MG Mgf model year on record is 2003 (80.3% across 61 tests), and the weakest is 2000 (75.0%). The gap between them is 5.3 points. Years with fewer than 50 recorded tests are excluded, so these are the years with enough MOT history to mean something.

MG Mgf reliability is improving in the DVSA data — the pass rate moves about 1.4 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 MG Mgf Owners

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

• the exhaust and emissions — “catalyst emissions carbon monoxide content after 2nd fast idle exceeds manufacturer's 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.

• corrosion — “component mounting prescribed areas prescribed area excessively corroded significantly reducing structural strength”

  Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.

• the windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
