2004 SEAT Leon 1.9L Diesel · OU04 RVV

Fuel economy from the 1.9-litre PD diesel unit is typically in the 45-55 mpg range on a mixed cycle, which remains competitive for a vehicle of this age. Road tax for a 2004 diesel of this engine size will sit in the higher pre-2007 bands, so budget roughly £200-£260 annually depending on current list price. Insurance for an SEAT Leon 1.9 TDI from this era is generally moderate — group 7 to 9 depending on trim — placing annual premiums in the £350-£500 region for a typical driver. Servicing should follow diesel-specific intervals with attention to cambelt replacement (typically every 4-5 years or 60,000 miles), and budget an estimated annual running cost of £1,200-£1,500 inclusive of fuel, tax, insurance and routine maintenance.

Begin with the brake system: the MOT history repeatedly flags corroded brake pipes on both sides and corroded brake hose ferrules at the rear, so a thorough inspection of the full pipe run and all flexible hoses is essential. Listen and feel for the front anti-roll bar linkages and lower suspension arm bushes — these were cited as excessively worn at the 2023 test, and replacement bushes alone often run into three-figure sums per side. Next, raise the vehicle and check the rear sub-frame for the corrosion flagged in October 2023; if it has progressed beyond a surface coating, welding or sub-frame replacement becomes a significant cost item.

The exhaust system merits close attention given the recorded minor leak at the front and the rear system insecurity noted on the 2023 failure. Check the 1.9 PD engine for timing belt service history and inspect the driveshaft CV boot, which split on the nearside in 2022 — a common failure on this platform that can lead to expensive joint replacement if left unattended. Finally, examine both front position lamps for correct colour (white rather than amber) and confirm the registration plate lamp functions, as these minor items have appeared repeatedly across the record. Given the 178,803-mile reading against an average of 8,134 annual miles for this model, also budget for wear items including wheel bearings and clutch if not recently replaced.
