i have reported the problem "the car starts and the RPM drops after 5sec, the engine goes off, and when starting it again it works fine, this only happen when the car is warm" to VW agent, they said the problem is with the "ACF" valve, they replaced it, the problem still existing and not solved. i have reported it again, and handed over to them again, the replaced the fuel charcoal filter and the vent valve of the fuel system. and the problem still existing. i started to hate the car as it is annoying and impressing me regardless of how excellent experience of driving it.
