Here we go again...

Moin boys,

after having been allowed to drive almost 3 weeks without big disasters, the bezel starts to bitch again.

First problem: exhaust gas is sucked in by the ventilation of the air in the stand and while driving. Where does the climate get the fresh air? The exhaust can't come directly from the engine, so it has to have something to do with the exhaust, Kat, X-pipe.

Yesterday evening I briefly actuated the windscreen washing system where up the good part of the opinion was it would have to now empty the whole container (7.5 L I think) windscreen wipers were also no longer to be moved to stop... Has anyone ever had this before? Steering pole switch?
