2018 Hyundai I30 1.6L Diesel · NJ06 SCO

The 1.6-litre diesel i30 is one of the more economical variants in the range, typically returning around 55-65 mpg on a mix of motorway and town driving, depending on driving style. As a car registered between 2017 and 2020, this vehicle falls into a relatively low road tax bracket for a diesel, though it will not benefit from the zero-rate diesel exemption that applies to newer low-emission vehicles. Insurance for the i30 generally sits in groups 10-14, making it a mid-range proposition for most UK drivers. Estimated annual running costs sit in the £1,000-£1,400 range when combining fuel, tax, insurance, and routine maintenance such as tyres and brake pads. Given the vehicle's current mileage of just over 61,000, anticipate that brake pads and tyres may soon need replacement if not already addressed. Diesel servicing tends to be marginally more expensive than petrol equivalents due to oil capacity and filter costs, but parts availability for the i30 is generally good through main dealers and independent specialists.

Begin with a thorough inspection of the tyres, including tread depth across the full width and check for uneven wear which can indicate suspension or alignment issues — tyres are the single most common MOT failure point on this model. Inspect the brake pads and discs through the wheels, looking for lipping on the disc edge and pad material thickness, as brake components rank second in typical failure reasons for the Hyundai i30. The suspension arms are the third most frequent failure area, so push down on each corner of the car and release to check for excessive bouncing, and listen for clonking over speed bumps which suggests worn bushes or drop links. Check the diesel-specific components carefully: look for exhaust soot around the rear bumper suggesting DPF issues, and on a cold start listen for any rattling from the EGR valve area. Examine the cambelt cover for any signs of recent work, as the timing belt interval for this engine falls due around this mileage. Finally, confirm all electrical systems work including the infotainment screen, air conditioning, and rear parking sensors, and verify that the diesel particulate filter has completed recent regeneration cycles by checking for any dashboard warning lights during a test drive.
