Guten Tag Herr,

Bear in mind I’m no expert on your engine! I’ve owned 2 - 850’s (5 cylinder) and a 240. The 5 cylinder engines are basically your engine minus 1 cylinder. Modular design. One difference is that 850’s are distributor driven not ignition coil driven. 1999 models (S70/V70) were the first year the 5 cylinder engines got ignition coils and VVT.

That said, the circular turquoise thing is probably your camshaft sensor. Is there an electrical wire attached to it? If so, it could be the camshaft sensor. Don’t think your engine has VVT (variable valve timing). The sensor was fairly easy to remove on my 95 850. It was awhile ago, but as I recall I was able to gradually work it out with no special tools. If you remove it, I strongly suggest replacing both the exhaust camshaft seal and the camshaft sensor while you are in there. My goal was to replace the camshaft sensor as I was dealing with a no start situation.
