About This Data

The 2005 Proton 1.3 Gls has an MOT pass rate of 56.3% based on 135 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 47,121 miles on the odometer. With a 43.7% failure rate, the 2005 1.3 Gls is rated as "Below Average" for MOT reliability.

If you own or are considering buying a 2005 Proton 1.3 Gls, budget for potential repairs before each MOT. Before your MOT, pay particular attention to noise, emissions and leaks: 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. With relatively low average mileage of 47,121 miles, many of these vehicles are still in good mechanical condition.

Noise, emissions and leaks — 0.7% of failures

Noise, emissions and leaks issues account for 0.7% of MOT failures on 2005 Proton 1.3 Gls models. 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.

Seat belts and supplementary restraint systems — 0.7% of failures

Seat belts and supplementary restraint systems issues account for 0.7% of MOT failures on 2005 Proton 1.3 Gls models. Seat belt failures include frayed or cut webbing, faulty retractors, buckles that don't latch properly, and missing or damaged anchorages. All fitted seat belts must be functional. Typical repair costs: £50–200 per belt. Pre-MOT check: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard.

Tyres — 0.7% of failures

Tyres issues account for 0.7% of MOT failures on 2005 Proton 1.3 Gls models. 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.
