About This Data
The 2008 BMW 325i M has an MOT pass rate of 78.0% based on 423 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 64,014 miles on the odometer. With a 22.0% failure rate, the 2008 325i M is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2008 BMW 325i M, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: 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. At 64,014 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Tyres — 3.1% of failures
Tyres issues account for 3.1% of MOT failures on 2008 BMW 325i M 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.
Suspension — 1.7% of failures
Suspension issues account for 1.7% of MOT failures on 2008 BMW 325i M models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Exhaust, Fuel and Emissions — 1.2% of failures
Exhaust, Fuel and Emissions issues account for 1.2% of MOT failures on 2008 BMW 325i M 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.
