AFM! Had the same prob in my valver!
revin by itself
yeah had this problem with mine to tho mines a gsi its still got the bosh ign system!
on the right had side of the throttle housing u will have two breather pipes if u follow them down i cant rember wich one but it will go into a cylinder along with two bigerr breathers and one coming out the bottom.
if u disconect all and remove this cylinder spray it out with wd40, and get a small flat blade screwdriver, look inside the big breather on the side of the cylinder and inside the is what would apper to be a switch, flick it open a few times with the screw driver and put it all back together!
it may rev quite high for about 30sec but after it will be as good as gold!
if not on the back of the throttle housin there is a throtle position sensor looks like a black box held in with two screws with wires going into it!
this my need adjusting if not u are looking about ?100+ for a new one!
hope this helps but this problem is verry common on bosch ign systems
