VW DIAGNOSE FAULT WRONG , HOLDING OWNER ACCOUNTABL

We purchased a brand new Amarok 2.0TDI from Lindsay Saker Krugersdorp in 2011 and started experiencing a defining vibration in the vehicle travelling in the range of 68-74km/h. The vehicle had 88000km on the ODO meter at that time . We then proceeded to take the vehicle in to the above mentioned dealer even before the 90 000km service as the vibration was of concern . When we took the vehicle in we were told that the fault was our tires ,to be exact we were told that the tires had flat spots on them .<br> <br> My father did not agree with the diagnosis and felt it was ridiculous for us to fit new tires at a cost of R10 000 on our behalf as our existing tires had atleast another 40 000km still to go and the diagnosis was based on an assumption that the \flat Spots\" were the cause of the vibration in the specified speed range.<br> <br> I fitted the vehicle with new tires and rims and this DID NOT SOLVE THE PROBLEM! I told VW LS Krugersdorp that it was my propshaft to which the dealer principle ( Alta ) disagreed, according to her sources . I took in the vehicle again to have the propshaft replaced from a demo model for testing which SOLVED the problem . Now VW refuse to pay for the full repair "
