Servus I have recently been a quit out of the engine room. What amazes me: – it only occurs after 1-2min – only from the 3rd gear at the slanting – then it only stops for 1-2min and then remains silent the whole driving time. – hummed when I walk from the gas – comes from the passenger side. – after 30min parking, the procedure stops. I switched to the WE OIL and had only the assumption that what came on the belts, but nothing can be seen from above. s the next agregate hang short? Otherwise nothing inconspicuous can be observed. Before I buy new straps and spanners now, did one have an idea or similar?
