Hello, we play with the thought to sell the 407 SW. For this reason yesterday as today someone was there who wanted to test him. (unfortunately again all strange guys want to take with them the best still money, for that they take the vehicle) Yesterday everything was ok, the guy kicked on the gas etc., a few little things many him of course on etc. (no eye-catching, except the belt strapper/airbag error the cable, see other thread I wanted to make still) Today I am of the opinion that he deliberately distracted us to manipulate the vehicle. He had removed the cover from the engine block (i.e. the plastic cover), did not run round and what he still said. We had let him drive alone, it also took quite a long time until he came back. Then, only step speed, errors in the display: “Faultmeltung: Motor error – vehicle repair” Frauchen said that we had already had that already when we did kickdown in cold condition ten, that was after 3 days or so away again (or over kilometers, I know what) Personally the mistake was new to me. Anyway, not only the error lighted up, at once the engine runs quite unevenly, or it wobbles as if it is loose at once. Strangely only that the guy went down in price, only hobbyists carre etc. Engine damage, after we still refused, he went up with the price, drove away, came back at once, etc. (somehow strange) Can it be that he has loosened something that suddenly swings like this? We had never before. I also had read the following about this error: Quote: in the area of the throttle flap sits a small black plastic hose, approx. 8 cm long with 90° bow, approx. 3 mm inner and 8 mm outer diameter. On one side it was swollen and porous. Fixed changed and everything is good again. Quote end. Because that came again and again, it seems very strange to us, since yesterday also That with the kick down is apparently known or brake + gas at the same time (or so) compels this error. How can I look now in the engine room what it could be all at once?
