I've been looking to find answer but unfortunatelly didn't....my B4 has weird throttle response when idle, runs ok, but when i press throttle pedal when idle, it has kind of delay. It doesn't catch from the beginning. Interesting thing is that after some reving, or driving on high revs and stopping after, throttle response seems ok. I tested throttle pedal potentiometer with vag com and it seems fine, and also tested with vag manual by measuring resistances between pins on the connector and it's all ok. Does anyone have any idea about it? Could it be injectors?

Yeah, therefore I'm in doubt with injectors, there are no faults, everything is fine except that odd thing and by now nobody could help me with that. It's actually annoying thing sometimes, and I know that it shouldn't be so....every tip is welcome.

My B4 does the same thing, top of pump was replaced to try and sort it but it didnt
Mine wont do it when its hot, sometimes if i put the throttle down hard in first gear and let it up quickly to change to second it stays revving and you get some wheel spin in second, then going to third it will delay the throttle
quite annoying pulling off from a junction

If it doesn't theres a sensor problem, if it does and your temperature stays quite low then you might have a thermostat issue, these tdis don't get hot easily especially in Ireland during mornings and at night driving on fast roads the radiator does too good a job.
This was my problem, new thermostat and coolant fixed it but problem persists when cold so I can't help you after that but surely someone else can shed light on this issue
