Hello SL municipality, during this holiday we suddenly heard a very funny noise in the “Heck”. It sounded as if an aluminium drink bottle rolls back and forth in the trunk. After intensive search I could only find out that it does not come from the trunk or in the rear interior. So exactly in between. And there is probably the tank. A search in the net revealed that it is probably a well-known problem with the R230 that a swarm plate dissolves in the tank. (A Benz for almost 100T€ and it resolves itself a sheet metal in the tank. I can’t believe it.) OK. There’s probably only a tank to be renewed or a company like that in Stuttgart (I think). OK. Then there’s clackers. I don’t think there’s any other DIY solution at the moment. Then today the next one. The trunk doesn’t seem to close properly anymore. Otherwise it sucks in autom. It doesn’t do that anymore. Apey to be a pneumatic lock. Here’s my question, which DIY error analysis can you do? a) will be there Schl If so, where is this? b) I have pressed in the hook of the lock with an open lid once a position by hand. It does not happen. So you don’t hear anything. When I press the opening lever, the hook goes back and you hear a pneumatic hissing. But just when opening. Is this correct? Thanks for the first DIY tips.
