I swear i answered this

btw i have never done this, but this is from what i have read
The injectors just pull out, but you can use a screw driver and a hammer to lever them out, VAG ones are about $40 each, gsf ones are about £28 each, but the best one you can get are merc ones £32 each, they are brass and will last a very long time, pm me and i'll send you the part number.
Do a search on clubgti forum, as there is alot of info on there!
First though, pull them out and put them in a jar and test the spary pattern, should be cone shaped, then let them sit overnight and see if they leak. Note - I think you need to remove the centre spark lead before you do this so you don't start the car, better check on that!
you need 2 x o-rings per injector one smaller than the other, couple of quid from vag, use the vag ones as they will last longer!
hope that helps
