Answer 1

Here are a few suggestions on how to troubleshoot and potentially fix the issues with your Astra diesel 1.9 that is showing codes P0380 and P2279:

Code P0380 indicates a glow plug control module issue. This module controls the glow plugs that help heat up the engine when cold. First thing to check would be the wiring harness and connections to the glow plug control module. Look for any damaged/corroded wires or loose connections. The module itself may need to be replaced if faulty.

Code P2279 refers to the intake air system - likely an issue with the swirl flap motor or system. The swirl flaps help optimize air flow into the cylinders. I would inspect the swirl flap motor and linkage for any binding or damage. The motor may need to be replaced. The swirl flap control valves could also be stuck or faulty.

These issues can definitely lead to poor engine performance and power loss as you've experienced. When the engine has trouble starting or doesn't warm up properly, it won't run smoothly.

Other basic inspections: check for intake/vacuum leaks, clean the MAF sensor, check fuel pressure and filters. Make sure no basic maintenance like air filter, spark plugs, etc is overlooked.

Plan on replacing the glow plug control module and inspecting the swirl flaps and motor. May need to replace swirl flap motor if binding/damaged. An experienced diesel mechanic can troubleshoot further and pinpoint the exact faulty components. Expect $500-1000 or more for parts and labor if major components need replacement.
