Hello forum, for the first time I would like to introduce myself to Stefan 34 years from Bremen, and since the age of 18 Opel Fan / Schrauber. now to my problem, I am looking for a “new” car my current car a Vectra A v6 has now nearly 300150km on the bump and it is looking for a worthy replacement. I have a Opel Omega B MV6 in mind which could buy cheaply from private. the vehicle has very few defects, but the largest is that of the engine of the interior ventilation nich t works. now I would get into it because I don’t know the vehicle so, where does the engine sit how hard is it to replace it? where does the pre-resistance sit? does the omega with automatic climate control have a different engine than the without automatic climate control?
