The faults that decide it

BatteryHigh

PHEV drive battery capacity down, shorter electric range than claimed

Typically appears: 60,000+ miles

Typical repair: Significant repair · £400–£1,400

EngineHigh

Diesel DPF blocking on short urban runs

Typically appears: 50,000+ miles
What to inspect: Check for repeated regeneration attempts in the service history and warning lights on a cold start
Typical repair: DPF forced regen or replacement · £250–£1,600

HVACHigh

No cabin heat when running in pure EV mode due to a failed electric PTC heater element.

Typically appears: 50,000-80,000 miles
What to inspect: Turn the car to 'Ready' mode with sufficient battery. Set climate control to maximum heat, turn off AC, and ensure the petrol engine hasn't started. Feel the vents for hot air after 60 seconds.

ElectricalMedium

12V battery flattening when the car sits, refusing to wake the hybrid system

Typically appears: Age-related
What to inspect: Leave the car locked for an hour then check it starts and the charge timer works
