Hello! I am delighted to report that I have found the culprit who is responsible for the wrong air! And that is the colleague on picture 1 of the culprits! On picture 2 you can see where he pulls massively wrong air. So, he’s probably perforated! My LMM seems fine and the Lambda too, but more precisely you can say after the exchange. What should I do now? Exchange against the original product, or as I would like to have it against the following to ta uschen:http://www.snabb.us/…e-Fresh-Air-Pipe-99-00-SV70-99-05-C70_p_11.html The part costs twice as much, but … it’s worth it! There’s also a video where the part of FCP-Europe is installed.
