Common Problems: MG ZT
Known issues reported by owners and MOT testers.
- ECU Flooding (Blocked Drains)(Serious)
The plenum chamber drains block with leaves, causing water to rise and submerge the engine ECU.
- Front Coil Spring Breakage(Moderate)
The front coil springs are prone to snapping due to fierce corrosion, particularly on UK roads with salt and potholes. This is a common MOT failure.
- K-Series Head Gasket Failure (1.8 Petrol)(Serious)
The 1.8 K-Series petrol engine is prone to head gasket failure if the cooling system is neglected. Symptoms include overheating and oil/coolant mixing.
- Brake Pipe Corrosion(Serious)
The brake pipes can corrode, particularly in areas where road salt is used. This is a serious safety concern and a common MOT failure point.
