The Scala shares VW Group underpinnings and diesel engines are typically the 1.6 TDI used for efficient cruising — paired with a manual gearbox that’s inexpensive to maintain if not abused. Diesel Scalas thrive on longer runs; if most ownership has been short urban trips you should be alert to clogged DPF / EGR symptoms and check clutch condition on a manual car. Used-diesel demand has softened in recent years, so resale can be more modest than petrol equivalents.

• DPF behaviour and regeneration history — ask if the car has done regular long motorway runs and watch for frequent forced regenerations or long white/black smoke after start
• EGR/intake soot buildup — rough idling, loss of power or limp-mode can indicate heavy soot in the EGR/ intake tract
• Clutch and dual-mass flywheel condition — test for slipping or judder during acceleration and check clutch bite point for excessive wear
• Turbocharger boost and intercooler hoses — check for whistle, lag, or black soot around boost hose joins which can indicate leaks
• Timing-belt/cambelt replacement interval (if fitted) — confirm whether the cambelt has been replaced or when it is next due
