KS03 CXH MOT History
Interpretation generated from the recorded test data above — not an official DVSA statement and not a substitute for an independent inspection.
22 MOT tests are recorded for this 2003 Mg Zr (KS03 CXH) between December 2006 and January 2021.
The record contains 14 passes and 8 failures.

Across all tests, the most frequently flagged areas are: Brakes (25 issues), Tyres (21 issues), Lighting (8 issues), Suspension (8 issues), Steering (1 issue). Repeated mentions in one area can indicate an ongoing pattern worth checking in person.
In total 43 advisory notices are recorded. Advisories flag items that passed but may need attention before the next test; they are not evidence of how well the vehicle has been serviced.
Recorded failure items include: “Offside Outer Drive shaft joint constant velocity boot split or insecure, no longer prevents the ingress of dirt (6.1.7 ”; “Nearside Outer Drive shaft joint constant velocity boot split or insecure, no longer prevents the ingress of dirt (6.1.7”; “Offside Front Tyre has ply or cords exposed (5.2.3 (d) (ii))”.
Common Problems: MG ZR
Known issues reported by owners and MOT testers.
- K-Series Head Gasket Failure (HGF)(Serious)
The K-Series engine is prone to head gasket failure due to its small coolant capacity and plastic locating dowels that allow the head to shift.
- SCU / BCU Failure (Pektron)(Moderate)
Later models (2003+) use a Pektron SCU that controls windows, fobs, and wipers. It is notorious for relay failure.
- Worn Front Suspension(Moderate)
The front suspension bushes and ball joints wear out, leading to vague steering, knocking noises, and poor handling. This is a common MOT failure point and can be exacerbated by hard driving.
- Coil Pack Failure(Moderate)
The ignition coil pack is known for failing on the ZR, causing misfires, rough running, and difficulty starting.
- Door Lock Failure(Moderate)
The door lock actuators, particularly on the driver's door, are known to fail, making it difficult to lock or unlock the car.
