What the reviews say

• An owner of a 2014 2.0 diesel praised its comfort, generous equipment and year-round roadholding, but noted low clearance and costly maintenance.[3]one source
• The same owner reported that the suspension held up well even under heavy use.[3]one source
• Diagnosing 2.0 CDTi running faults can be difficult: forum cases considered the DPF, injectors, wiring, fuel pressure and electrical system.[1][2]
• The complaints database is extremely sparse, with one report each for 2013 and 2015, so it cannot establish the model's overall reliability.[4]one source

Typical faults

• On the 2.0 diesel, failure to replace the oil-pump seal in time can cause low oil pressure and ultimately require an engine rebuild.[3]one source

  2.0 diesel

• In one 2.0 CDTi case, a blocked DPF put fuel into the sump; the oil pump failed and the engine required extensive repair.[1]one source

  2.0 CDTi

• A forum report says the automatic transmission may begin jerking around 200,000 km if its oil has not been changed.[3]one source

  200 000+ km

• On 2.0 diesels, the turbo or intercooler hose can crack, causing black smoke under acceleration and loss of power.[3]one source

  2.0 diesel

• The water pump may begin leaking before the timing-belt replacement interval.[3]one source
• The NOx sensor was described as a typical 2.0-diesel fault, usually appearing at 80,000–120,000 km.[3]one source

  80 000–120 000 km · 2.0 diesel

• A coolant leak from the seal beneath the EGR valve was reported; it may be mistaken for a head-gasket fault.[1]one source

Which engine and version to take

• The only positive petrol example is a 2019 1.5 at 85,000 km: its owner found no faults or warranty repairs, but complained of high fuel consumption.[3]one source

What to avoid

• Avoid a 2.0 diesel without proof of oil-pressure-system and DPF care: the sources link failures in these areas with expensive engine repairs.[1][3]

What to check at the inspection

• Verify a documented service history; forum contributors particularly warn against cars with an unknown past.[5]one source
• For a 2.0 diesel, demand evidence that the oil-pump seal was replaced and have the oil pressure checked.[3]one source
• Check the DPF, pressure-sensing glow plugs and any signs that fuel has contaminated the engine oil.[1][3]
• During the test drive, watch for fluctuating idle, jerking and stalling, and scan faults with Opel-capable diagnostics.[1][2]
• For an automatic, verify its oil-change history and check that it does not jerk under load.[3]one source
• Inspect the water pump, turbo hose and area beneath the EGR valve for coolant leaks, cracks, black smoke and loss of power.[1][3]
• On a four-wheel-drive car, verify Haldex oil and filter servicing and confirm that the rear axle engages.[3]one source
