Oil leaks, diesels and campaigns on the Insignia BKnown weak points

Engine / equipment: Opel Insignia B (petrol and diesel)
Period mentioned: 2017–2022
Symptoms: 1.5 and 2.0 Turbo petrols: no major known faults, but the inspection sometimes finds oil leaks. Diesels: timing chain on the 1.6 Turbo D; a cracked turbo on the 2.0 biturbo (2018–2019) with a fire risk; a fuel line chafing on a bracket on the 2.0 (July 2016–November 2018); plus particulate filter, dual-mass flywheel, turbo, EGR and injectors at high mileage.
Possible cause described: The biturbo turbo and fuel-line faults were handled by recalls; the 2016 2.0 diesel also got a voluntary emissions software update.
Check for the garage: Look for oil marks under the engine; check the campaigns by VIN; on diesels, listen to the chain.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 1.6 / 2.0 CDTI (Diesel)

Opel CDTI EGR cooler and timing beltEGR / timing

Engine / equipment: Opel 1.6 CDTI (B16DTH), 1.7 CDTI (A17DTR) and 2.0 CDTI (A20DTH) diesels: Astra, Insignia, Meriva, Mokka, Zafira, Corsa and Cascada
Period mentioned: 2006–2019
Symptoms: Coolant loss with no visible leak or white smoke (cracked EGR cooler); power loss and rough idle (clogged EGR); on the 2.0 CDTI, water pump noise before the belt breaks.
Possible cause described: On the 2.0 CDTI the EGR cooler cracks internally (common between 100,000 and 180,000 km) and the timing belt, on an interference engine, breaks early, often because the water pump seizes. On the 1.7 CDTI the EGR fills with carbon between 80,000 and 150,000 km. On the 1.6 CDTI the EGR cooler also leaks internally.
Check for the garage: Watch the coolant level, check whether the 2.0 CDTI belt and water pump were replaced together and inspect the EGR.
Cost cited in the source: 2.0 CDTI EGR cooler: approx. €550–1,650; belt kit with pump: €450–750 at a German garage; 1.7 CDTI EGR: €370–1,100 (converted from dollars)A rough figure from the original database, not an up-to-date quote.

Mileage cited in the database: 80,000–180,000 km. This is not a maintenance interval and does not predict a failure.
