Engines: 1.8 / 2.2 (Petrol)
Applies if: Only Vectra C with ECC climate control, partial VIN range 21000015–21031422 described by HELLA, unit S3.10/S3.12. Not the Signum or units with different equipment; confirm the full VIN.

Applies if: Only if fitted with the M32 six-speed manual (common on six-speed turbo and diesel versions); confirm by VIN.

- 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.

1.9/2.4 JTD intake flaps, EGR and flywheelIntake / EGR / flywheel
- Engine / equipment
- 1.9 JTD / Multijet (8 and 16 valves), 2.4 JTD and JTDm in Fiat, Alfa Romeo 147, 156, 159, GT and Brera, Lancia and the Opel 1.9 CDTI
- Period mentioned
- 1997–2012
- Symptoms
- Power loss, rough idle and an engine light with “swirl actuator malfunction”; soot around the intake manifold; vibration and knocks in low gears (dual-mass flywheel).
- Possible cause described
- On the 16-valve 1.9 and 20-valve 2.4, the intake flaps seize with EGR soot and oil, and the control rod comes off as its plastic bushes wear. The EGR fouls in town use and the dual-mass flywheel wears between 80,000 and 150,000 km. The 8-valve 1.9 has no flaps.
- Check for the garage
- Check the rod and flap operation on top of the manifold, read actuator codes, inspect the EGR and listen to the flywheel when starting and stopping.
- Cost cited in the source
- Intake manifold: €400–900 in parts; EGR cleaning: €150–250A rough figure from the original database, not an up-to-date quote.
Mileage cited in the database: 80,000–150,000 km. This is not a maintenance interval and does not predict a failure.

- Only configurations, equipment and VINs included in the documented assignments.
- Period mentioned
- Bulletin-specific period and equipment stated in each assignment.
- Symptoms
- The source describes the risk stated under cause; it does not document DTCs or additional advance symptoms.
- Possible cause described
- An excessively tight upper-hose bend can transmit vibration and cause cracks and power loss.
- Check for the garage
- Inspect the upper intercooler hose and routing; replace if damaged with an adequate bending radius.
- Cost cited in the source
- No verifiable estimate; request a diagnostic and repair quotation.A rough figure from the original database, not an up-to-date quote.
