I have just purchased an 08 Volkswagon Tiguan 2 litre diesel to tow my Bailey Ranger 460/2. We took it out last weekend for the first time. We were concerned to hear a double knocking sound (or banging) from the rear of the vehicle when we went over a pot hole or dip in the road. This didn't happen every time, but it was quite alarming, and we could feel it through the chassis. I have just had the suspension checked at the dealers and everything is apparently okay. It doesn't happen when we are solo.
