Tyres — 7.0% of failures
Tyres issues account for 7.0% of MOT failures on the Subaru Impreza Wrx Sti 330s. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Exhaust, Fuel and Emissions — 7.0% of failures
Exhaust, Fuel and Emissions issues account for 7.0% of MOT failures on the Subaru Impreza Wrx Sti 330s. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
Driver's View of the Road — 2.3% of failures
Driver's View of the Road issues account for 2.3% of MOT failures on the Subaru Impreza Wrx Sti 330s. Driver's View of the Road issues are a common cause of MOT failure.
