• Sudden loss of power / engine cuts out
• DPF warning light (may not be persistent)
• Oil pressure warning light
• Complete engine seizure - car will not start

The Z17 DTH 1.7 CDTI engine has a timing belt, not a chain . The official replacement interval is 10 years / 60,000 miles . Some Vauxhall dealers have recommended 40,000 miles due to early failures . The 1.3 CDTI (Z13 DTJ) uses a timing chain .

• DPF oil dilution is the primary concern
• Warning lights may not be persistent
• Engine seizure can occur without warning

It depends on the vehicle's value and what has failed. For a 2003-2010 Meriva diesel worth £800-£3,500, a £1,200-£2,800 rebuilt engine is usually worthwhile if the car is otherwise sound and in good condition. For sub-£1,000 examples, consider a used engine or scrap.

• Cars worth £2,000+: rebuilt engine with warranty is recommended
• Cars worth £1,000-£2,000: evaluate both options carefully
• Cars worth under £1,000: consider used engine or scrap
• 1.3 CDTI engine seizure: often cheaper to replace the engine than repair the damage
