Hello everyone, would have a few questions about the Citroen C1. On the one hand to the exhaust. After the replacement of the exhaust (completely from KAT) it happens (especially if the climate is on) that the exhaust in the area of the curvature hits between the pipe and end pot to the body. Not continuously but occasionally. What can it be about? What does it have to do with the air conditioning? On the other hand, on the subject of clutch. This probably has to be replaced. For a time the clutch was at a certain speedb After adjustment, no longer, but the first gear can now be put in worse. Accordingly, the clutch has to be replaced, right? Can it be that a defective clutch causes certain knocking noises while driving?
