Moin, I’m in despair with my car. For 6 months I’ve had problems with a loud squeaky/twisher in the engine compartment. I’ve changed almost everything where the V-belt runs over it (clamp roll, pulley, pulley, water pump, V-belts themselves 3-4 times, air-conditioning compressor 2 years ago) I tried it with V-belt spray but it just got louder. It’s the loudest in the morning and stops about as soon as the engine is warm, nothing changes from the driving feeling . I’m so nervous that I’m about to sell the car. I’m looking forward to replying.
