Hello, I have a few general questions in addition to the small problem in the other thread. I hope I’m not annoying you with it Since I’ve read a lot of articles I’d rather ask you a bit more. Here’s my model: Aero, Bj2003, MY2004, 250PS, Kombi 1. The filled oil is “Motul 8100 X-cess” – according to my research a good oil, but also effective for my Saab? http://www.elferteile.eu/…tisches-motor%C4%86%C2%B6l-p-11901012.html Es is a fully synthetic oil that should be suitable for turbomotors. Shouldn’t a zero oil be pure?? 2. It should be a SID2. 1. I don’t have a plan on what I recognize that and 2. what’s better about it? 3. Audio system – lt. display is a system with 150W and 7 speakers installed, so an AS2. But find that the sound is pretty good, it sounds like subwoofer, only how can I find out which system is really inside?? 4. again Audio system – Da The factory radio is good, but I don’t really need a tape and in itself I wanted to get a system with USB instead of (or incl.) CD drive. Which models work with the SID and the steering wheel remote control? 5. there is a tiny cover plate missing in the front door behind the grip, where do I get such a thing? So far so good, I think even more, would be great if you could help me understand my nisse better
