The Formentor is a Cupra-branded compact crossover — not an estate — and a 2024 diesel manual will usually be a Euro6d-compliant TDI with DPF and likely an AdBlue system. The manual gearbox is mechanically simpler than DSG and tends to be cheaper to maintain, but diesels need regular longer runs to avoid DPF/EGR carbon buildup; owners often prefer them for high-mileage motorway use. Cupra-spec trims may have firmer suspension and sport brakes, so expect a slightly firmer ride and check for evidence of aftermarket remaps which are common on this model.

• DPF and EGR condition — ask for evidence of long motorway runs or recent forced regens and check for warning lamp history
• AdBlue tank/consumption warnings and any related fault codes (AdBlue dosing faults can be expensive to fix)
• Clutch feel and slippage under load; test from low revs into the mid-range for judder or slip
• Signs of aftermarket remap or stage tuning (boost gauge changes, receipts, or ECU flashing history)
• Suspension and underside for scrapes/damage from lower sport setup, plus uneven tyre or brake wear from spirited driving
