Greetings!! I’ve been having a funny sound in the area of the left wheel suspension for about 3 days. It sounds like a RIESIG screw in a pot of Lohse!! It sounds horrible, especially when driving away! ( Drawn sound ) The noise only appears when accelerating. It’s soo loud that you can hardly drive with open windows, even when the window is closed you can hear the noise. From about 50 km/h you can hear nothing, even when speeding up. Have a technni ker (telephone) asked what that might be, he meant that the KAT might have been broken, but is unlikely for me… because the KAT is sitting a little further in the back (under the driver’s seat about….I think I did). I was driving back into a small pebble pile about 1 week ago (that was finer pebbles), and I think that maybe one or two stones in my left exhaust came in..and worked out to the Krummer, and the The technician has denied it that a stone could be the cause. Hope you can help me!!! Thank you in advance. mfg
