Mine's at it too, are they all wearing out at the same time?

Must be something they've put in the fuel!

ok noticed 2 things tonight:

1)if i am stationary and hold the throttle at say 3k the revs still go up and down from 2800-3000rpm,if it was at idle i would suspect isv but its when you are in the rev range but it now is lump at idle

2)my inlet manifold;-on the back there should be 2 inlets where the vacuum pipes connect,my one has all th pipes going to just one as the other pipe has broken clean off and has a boly blanking it off.Been like this since i bought it.Unsure if it makes much difference as all the pipes go into the inlet manifold.

Did you ever get to the cause of this.

yes i visited jamo on my way back from up the line and he kindly vag-comed it for me.due to a boost leak i found the week before in the ic hose it was over boosting to 2.5 bar

basically this played hell with the sensors,so we did the usual s2 re-boot....pulled out the motor fuses and re-installed,all was well after
