DPF blockage and the diesel particulate filter fire-risk recall
SeriousExhaust & EmissionsThe headline fault on diesel Antara models (particularly the 2.0 CDTI and 2.2 CDTI) is DPF blockage caused by frequent short, urban trips where the exhaust never achieves passive regeneration temperatures. Under recall R/2015/137, Vauxhall recalled 2.2 CDTi models due to lower engine cover fire risks caused by excessive exhaust heat during uncompleted regenerations. DPF cleaning costs £200–£400, while neglected soot build-up or full filter replacement easily climbs above £1,500 to £2,000.

- Ask how the car has been used and look for motorway-heavy service records
- Check that no DPF or engine warning lamp appears during a cold start and test drive
- Confirm the recall campaign is closed, including the revised lower engine cover
- Insist on a forced regeneration and soot-load reading before buying any high-mileage diesel
