On my way back to South Wales from Cornwall on Saturday and I started to have problems. The car started to stutter a bit (almost like bad fuel). Above 3500 rpm car seemed to be better but still stuttered when applying throttle (fine when off throttle). So I hooked up the vag com and I get this :- 17967 Throttle valve Control Part Fault in Basic Settings P1559 35-00 I tried clearing it with Vag com, but it just kept coming back, tried throttle adaption but this kept coming back with an error. I managed to get hold of another throttle body (same p\n AEB non dbw) Put this on but get the exactly the same issues. So I am a bit lost now. I suppose it could be another duff throttle body so I will try to get another. Anyone had this before ?
