If you own or are considering buying a 2020 Fiat Adria Twin Supreme 640 Sgx, you can expect reliable MOT performance overall.

Lamps, reflectors and electrical equipment — 3.3% of failures
Lamps, reflectors and electrical equipment issues account for 3.3% of MOT failures on 2020 Fiat Adria Twin Supreme 640 Sgx models.

Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Seat belts and supplementary restraint systems — 3.3% of failures
Seat belts and supplementary restraint systems issues account for 3.3% of MOT failures on 2020 Fiat Adria Twin Supreme 640 Sgx 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 — 3.3% of failures
Tyres issues account for 3.3% of MOT failures on 2020 Fiat Adria Twin Supreme 640 Sgx 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.
