For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help. At 79,180 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Noise, emissions and leaks — 24.2% of failures
Noise, emissions and leaks issues account for 24.2% of MOT failures on 1997 Volvo 400 Series models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel).

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.
Suspension — 6.1% of failures
Suspension issues account for 6.1% of MOT failures on 1997 Volvo 400 Series 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.
