Known faults on the 2012 Vauxhall Zafira diesel
Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.
- All engines
Heater blower resistor fire recall
The heater fan resistor can overheat and start a fire. The first recall fix wasn’t always done properly, so cars were recalled a second time.
At the viewing: Check every fan speed works. Ask a Vauxhall dealer to confirm both recalls were done.
- 1.9 CDTi diesel
Stalling and not restarting (1.9 CDTi)
The diesel can suddenly stall and refuse to restart, usually from a faulty fuel pressure regulator on the high-pressure pump.
At the viewing: Ask whether it has ever cut out, and check for warning lights.
- Manual gearbox
Sticky gearchange and scraping noise
Third to fourth can feel sticky and there can be a scraping noise between fifth and sixth. Fixing it means taking the gearbox out.
At the viewing: Change through all the gears and listen for scraping at around 2,000rpm.
- All engines
Starter that runs by itself
Water getting into the engine control unit can make the starter run when it shouldn’t.
At the viewing: Make sure the starter stops as soon as the engine fires.
- All engines
Wrong fuel gauge reading
A software fault in the instrument cluster can make the fuel gauge unreliable.
At the viewing: Compare the gauge with the trip computer’s range.
