2018 SEAT Leon 1.6L Diesel · HV18 WMJ

The 1598cc diesel engine in this SEAT Leon is designed for strong fuel economy, making it well-suited for regular motorway commuting and longer journeys. Road tax falls into standard UK VED bands for diesel passenger cars of this registration year, while insurance groupings typically sit in the lower-to-middle brackets for hatchbacks of this engine size.

Maintenance costs should include standard consumable items such as replacement brake discs, tyres, and periodic servicing. Based on current averages for this class of vehicle, you can expect typical annual running costs to fall within the £1,200 to £1,500 range, depending heavily on your annual mileage, local insurance premiums, and fuel price fluctuations.

Inspect the front braking system thoroughly; the January 2026 MOT recorded that both front brake discs were worn, pitted, or scored. Check whether these components have been replaced or if they will require attention in the near future. Examine the offside front drive shaft area to confirm the constant velocity boot is fully secure, free of splits, and not leaking grease following its recent rectification.

Inspect all four tyre sidewalls and tread depths carefully, remembering the 2026 test flagged an offside front tyre worn close to the legal limit and the 2024 test noted a nail in the offside rear tyre. Finally, verify that all external lighting, suspension coil springs, and electrical accessories function correctly, as headlamps and coil springs feature prominently as common failure points across the wider SEAT Leon model range.
