Was ist denn am Turbo kaputt?

@Adrian
Wenn ich es so lese gab es am Motor einen Schaden weswegen die ganzen Innereien des Blocks erneuert wurden ... sind Späne im System gewesen, ggf. durch Pleuellagerschaden etc.?
Ich könnte mir vorstellen, dass es durch den Schaden oder auch andere Schwebeteilchen im System den Filter in der Hohlschraube vom Ölrohr am Turbo zugesetzt ist und damit der Lader nicht mehr mit Öl versorgt wird, dass würde auch den schnellen Ausfall bei der Probefahrt erklären.

Siehe Pos.3 unter http://opposedforces.com/parts/impreza/e…/turbo_charger/

Folgende Dinge könnten auch passiert sein:
- Filter in der Öl-Hohlschraube am Turbo verdreht eingebaut -> Ölzufuhr Turbo unterbrochen
- Öl-Hohlschraube mit Schrauben vom AVCS vertauscht -> Turbo 15194AA110 -> AVCS siehe http://opposedforces.com/parts/impreza/e…illustration_1/

Zu den Fehlern gab es mal ein Service-Bulletin mit folgendem Wortlaut: "This bulletin is for informational purposes only. Turbocharged engines require proper maintenance especially when the vehicle is used under severe driving conditions, such as moderate to hard acceleration and engine braking on a somewhat regular basis. In any case, it is recommended that the engine oil and filter be changed every 3,750 miles (6,000 km) or 3-3/4 months. In addition, the mesh screen which is located inside the banjo bolt that secures the turbocharger oil supply pipe to the back of the right side cylinder head should be checked to make sure it is not clogged or restricted especially if the condition of the oil is questionable or as to when the last oil change was performed. If clogged or restricted, it will reduce or cut off the oil supply to the turbo resulting in failure. The oil supply pipe should also be checked to make sure that there are no obstructions. Note: The mesh screen is only available with a replacement banjo bolt.
- Make sure the mesh screen is installed in the proper direction; incorrect installation will cut off oil supply to the Turbo.
- Do not confuse the oil supply mesh screen with the Active Valve Control System (AVCS) union screw filter. Refer to Service Bulletin 02-97-05, dated 10/06/05.
- When the vehicle is used under severe driving conditions, the engine oil is consumed are quickly than under normal driving conditions due to high intake manifold vacuum during engine braking and higher temperatures; the engine oil level should be checked at very fuel fill up. For additional examples of severe driving conditions, refer to the Warranty & Maintenance Booklet."

Sag mal Bescheid ob es weiter geholfen hat bzw. wo der Fehler lag.
