Known faults for the Opel Insignia A.

Engine / equipment

Only configurations, equipment and VINs included in the documented assignments.

Period mentioned

Bulletin-specific period and equipment stated in each assignment.

Symptoms

Parking-aid, radio, climate-control, electric-tailgate or cluster faults; control-unit communication problems.

Possible cause described

Moisture entering the left rear radar may disrupt communication and cause faults in multiple systems.

Check for the garage

Inspect the left rear radar and connector; if corroded, replace the sensor and repair contacts according to diagnosis, then perform manufacturer calibration.

Engine / equipment

Getrag M32 six-speed manual: Opel Astra H and J, Insignia A, Zafira B and C, Vectra C, Meriva B, Cascada, Corsa OPC and some Fiats with the T-Jet engine

Period mentioned

2004–2019

Symptoms

A whine that rises with speed, mainly in 5th and 6th (also in 1st and 2nd), a loose gear lever that moves on and off the throttle and, when advanced, gears jumping out. Left unrepaired, the bearing can break through the casing.

Possible cause described

The bearings wear, mainly the shaft bearing next to 6th gear: the rollers develop play and the shaft moves under load, which reaches the lever. A specialist blames incorrect factory shimming. Second-generation boxes with the revised end case fail far less, according to an Australian repairer.

Check for the garage

In a garage test: confirm whether the noise depends on road speed (wheel bearing, tyre) or the gear engaged (gearbox), and whether the lever moves under load. Check the oil for metal debris. Repair early: replacing all bearings and fitting the revised end case costs far less than a new gearbox.

Cost cited in the source

One owner replaced only the main bearing for about £47 in parts versus about £1,000 for a rebuilt gearbox; another quotes about €600 at a specialist.A rough figure from the original database, not an up-to-date quote.

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.
