Dear people, I have a C3 II Exclusive with the 120hp engine (real 4-speed automatic transmission) and it claps and claps when I start or when I stand (except in idle). Now I was at a Citroen branch yesterday and they did a test drive. Feedback: I’ve never heard of it. Is probably a gearbox problem. Let’s not do it here. I thought so. The whole thing is as follows: 1. When I start the first time after engine start there is a physical S You can really feel it at the bottom of the foot and it’s always like that. 2. As soon as I stand (except in idle) the car claps from the bottom/left side. The guys also raised the car and could not see anything that caused it (also hotplate would be fixed). It’s probably the gearbox. It actually does so as normal when you take into account that the car has only 4 gears and you notice the 120hp zero. Has someone similar he problems and can report or a tip? Thanks already.
