I bought a VW Touran from Unicars in Cyprus back in 2003.
Since then it has been producing a loud low frequency sound, so loud that i can damage the hearing of anybody traveling in it.
When I contacted VW dealer in Cyprus they said that it was a designing problem and that it was the fault of the manufacturers VW themselves.
When VW Germany were contacted directly, said that Unicars in Cyprus have to examine the car. This has been going on for over a year and the result is that I became a tennis ball between the two, both stalling for time and not wanting to give a solution to the problem.
All these years of using the car, created a hearing problem to my right ear (the one nearer to the window) and as a musician creates direct problems with my work.
I believe that VW know about the problem but try to make it go away by allowing time to be blamed for it and "natural causes" and "wearing out" to be the creator of this sound.
I will post here the results of the tests that the government department will carry on my vehicle soon.
