2015 Vauxhall Antara 2.2L Diesel · R1 XDE

The 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.

RAC's Antara owner survey found electrical issues to be widespread across all model years, citing arbitrary alarm triggers, failing indicators, frayed wiring looms, electric window motor burnouts, and ECU/control module faults. These gremlins stem from moisture ingress, poor earth points, and fragile body wiring harnesses, necessitating diagnostic scan-tool tracing rather than indiscriminate component replacement.

Vauxhall Antaras suffer from elevated MOT suspension failure rates due to fractured or corroded road coil springs, weeping front suspension struts, and deteriorating suspension pins and bushes. Heavy curb weight combined with UK road salt exposure causes springs to corrode beneath their protective plastic coating before snapping on potholes, with multi-component front or rear axle overhauls reaching upwards of £900.
