Hello first of all. I read in for interest from time to time, but I have registered now, because I have a “larger” problem. Before I am referred to other threads – the flaps are all still there and supposedly also in perfect condition. It is an Omega 2.5 DTI caravan with manual circuit and approx. 130,000km (Y25DTH – the one from BMW) actually started everything with a routine inspection. In this case oil was determined on the wagon bottom. The Opel dealer has a e made engine wash to determine where the oil comes from. Strangely enough, the omega afterwards had incredibly little power – as if the turbo was missing. 2 weeks later back at the dealer he found that the oil comes from the turbo, it has a hair crack and the leaking oil also broke the engine damper. The missing power of the engine after the inspection was allegedly a hose blown off by the engine wash to the turbo… As far as good. After the replacement the turbo and the engine damper ran again everything – also the 1400km to skiing and back. After approx. 10km on the highway one hears first with acceleration a kind of Surren (engine was still cold). Also the typical cold startDieselRumpeln does not go away, as if the engine did not run on all cylinders. At once also still power is missing and when acceleration comes dark smoke from the rear exhaust. Stop is not, the highway has no standing track in this section. So h I am still about 1.5km with 80km/h to the next exit. There I called directly to a parking lot and ADAC. Now I have the diagnosis from my workshop. Engine can no longer be turned off. 6. Cylinder has run full of oil and the charging air cooler is also full of oil. The reason is unknown- he taps on a torn pleul. (at 130,000km???) He wants to change in addition to the engine also the injection pump and the turbo. (The turbo even on guarantee). Somehow I have Unfortunately the feeling that this workshop does not work very carefully and also has no plan to damage (probably carefully – winter tires were mounted with clearly different tyre pressures, hose to turbo in engine wash off). Perhaps someone can give me a tip here (except to change the dealer).
