Since my little fox has shown me recently the illuminated exhaust control lamp flashing or in continuous function, and three friendly independent of each other the diagnosis “longed control chain, (as a result wrong ignition times) incl. oil pressure dependent chain tensioner leaks, with rep. costs of approx. 1200,- Euro, I separated light hearts from the German-Brazilian coproduction. I now drive a Citroen C3, which is comparable in size to the Fox, otherwise jedo It has 4 cylinders and no control chain!!! In addition, the diagnosis with the control chain in the VW workshops about VW Wolfsburg is known, however, a client request is useless, since the satisfactory customer service apparently only works smoothly with the cars Touareg or Phaeton. So if you want to keep your Fox further, greet me the friendly ones and don’t let yourself be ripped off.
