[855 tdi]

Getting somewhere now, I jubilee clipped on the pipe from the IAC to the vacuum tree and it has almost sorted the revving out of control. It now idles at about 1500-1700RPM when cold then seemed to settle down to about 1k, almost drivable as it is. It no longer revs to 3 or 4k RPM and although it sticks a bit when revved I believe this is the throttle body.

I did however notice the odd pop from a misfire so I reckon there's another air leak to find.. great and secondly the throttle body seemed a bit sticky which isn't helping things. I thoroughly cleaned the throttle body but don't think I greased the spring so i'll do that and see if it helps. Seems like replacing all the clips and a few pipes to the IAC might be worthwhile too. Really praying I can get this sorted before I need it for a trip to Cornwall, even better the battery seems like it's on it's way out, this T5 is becoming a money pit before I even get to drive it properly.
