For the 2.0 CDTi engines, Vauxhall specifies a cambelt and water pump replacement every 100,000 miles or 6 years, whichever comes first. Dealers must check the service history for this, as failure causes catastrophic engine damage. If undocumented, budget for immediate replacement before retail sale to avoid liability.
The Aisin-Warner six-speed and later eight-speed torque converter automatics are generally robust, provided the fluid is changed every 40,000 to 60,000 miles. However, they are sensitive to neglected maintenance. During a test drive, watch for harsh engagements when shifting from Park to Drive, or flaring between second and third gears.
The AdBlue system on later Euro 6 diesels is a known weak point. Injectors frequently clog with crystallised urea, and NOx sensors are prone to failure. Ensure no emissions warnings are present on the dash. A failed AdBlue pump or tank heater often requires a complete, expensive tank replacement.
