Had the same problem with mine....stuck it on VAGCOM and it came up saying it was the ISV. I'd just had the top end on mine apart too.

 

Hope this helps mate

I've just had this problem...

 

Turns out the Keyway on the crank had gone which in turn bent my valves..

 

Happy Days!

Whats the keyway?

Would timing affect it oli? Timin was fine turned it by hand before crankin it for the first time.

Just had this with my VR..... MAF (air flow meter) was dodgy, cleaned it and its been fine since.

 

Also check the vac hoses, ABFs are very sensitive to the vac hoses going to air box/manifold etc.

 

After that try a known good ISV, my mates Ibiza ABF had the same issue and it was that.

been suggested about cleanin the isv out on cgti.

tried it with gunk lasnight, good idea?

got told to put petrol in it and let it swirl for few mins with connector plugged in/ignition on but wont be able to try til monday now.

how do i clean the MAF? wd4o?

changed some of the vac hoses to 4mm silicon tubing off ebay tightened on by zip ties so no leaks there

not sure how to change the ecu one

The MAF... use a cotton bud and a little alcohol, make sure its completely dry before putting it back in.

 

Sounds like the ISV though, I would take it off, put it in petrol overnight let it soak, then try it in the morning.

no maf on abf icy...

is fuel pump relay and ecu relay good and main earths on block ok?

has throttle body been checked to be within measuring blocks via vag-com?

ecu vacuum hose is small one (4mm) from throttle body and goes through bulkhead to ecu under scuttle tray

From memory only got hose from tb to airbox. Got hose on top left of top inlet to bulkhead? I changed those relays on last problem which ended up bein crank sensor. Thought that may be loose or somethin? On way to players so cant try til monday. Got guy comin with vag.com on monday to see if any codes come up. What settings should tb be at? Cheers
