AI Market Summary

Diesel engines deliver strong fuel economy and torque for motorway driving; spacious cabin and boot suit family use well.
Median price at €9,500 reflects +28% annual rise — market trending upward, so current stock may move quickly. Fair value now.
DPF clogging is the critical weak point: avoid cars with artificially low mileage or short-journey history. EGR carbon build-up causes rough idle and limp-mode faults. Electrical gremlins (switches, windows, infotainment) common but non-critical.
Get a pre-purchase diesel health check focusing on DPF status, last successful regeneration, and EGR condition. Request service history proof of motorway runs.
Check NCT history: failed emissions tests flag DPF trouble. Confirm all 3 recalls have been completed by dealer before handover.

Reliability & Safety Recalls

Opel Insignia 2018

Reliability

3/5

The 2018 Opel Insignia diesel is a solid mid-size sedan with a proven 1.6 CDTi engine, but ownership costs can be higher than petrol due to DPF and EGR maintenance. Build quality is reasonable and the car drives well, though electrical gremlins and gearbox niggles are not uncommon. Parts availability in Ireland is good, but diesel particulate filter issues are a recurring cost headache for this generation.

Known issues

Diesel particulate filter (DPF) clogging and regeneration failures, particularly on cars with low mileage or lots of short journeys
EGR valve and cooler carbon build-up causing rough idle and limp-mode activation
Electrical issues with dashboard switches, window regulators, and infotainment systems
Timing chain rattle on cold start (1.6 CDTi engines), though rarely fatal
Transmission shudder and judder on the 6-speed automatic, especially during low-speed manoeuvres and gearchanges
Fuel injector coking on direct-injection diesel engines, causing loss of power and increased emissions

Good for

Comfortable motorway cruising with low NVH and good fuel economy on longer drives (45–50 mpg real-world)
Spacious interior and large boot, practical for families and commercial use
Robust 1.6 CDTi diesel engine with reasonable longevity if serviced regularly
Good driving dynamics and steering feedback for a large saloon

Years to avoid: 2016, 2017
