Replace any blown bulbs before the test.
Suspension — 7.5% of failures
Suspension issues account for 7.5% of MOT failures on the Mercedes Viano Cdi2.2 Amb Xlong A. 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.
Road Wheels — 5.0% of failures
Road Wheels issues account for 5.0% of MOT failures on the Mercedes Viano Cdi2.2 Amb Xlong A. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached.
