Thanks for that, does it really serve any purpose then ?
I found the vac line and connected it back up and it's only maybe made a slight diffence to the way the engine stops. Any advantage in removing it, and if so how did you do it ?
You seem pretty knowledgeable on the 2.5 tdi reading past threads, any chance of some advice with my egr problem as per my other thread if you get the chance ?
Many thanks
