Hello, I had bought in 08/05 an Opel Omega B 2.0 16 V from a BMW dealer for 5,200,-EUR. Built 04/99 and 78000km down with checkbook. As far as I think so good. Now at 107,000 km the camshaft sensor was broken and I had it changed at another FOH (by moving other federal state). That said, the timing belt is not set correctly and a little loose. I told Him why you didn’t really tense this, he said, since we go for warranty talk It’s the FOH who changed it. Well, now I have a meeting Monday with the responsible customer service manager. How should I behave? Who would have to “change” it properly or “change” it”? Is this internally charged with the FOHs? Distance between new and old FOH almost 800 km…. Please for advice and tips, don’t want the engine to break. Thanks.
