mine broke when i was changing my valve cover gaskets. they get really brittle with age, i mean REALLY brittle. its very easy to install but the part is expensive. i spend around $80 at www.thepartsbin.com
. the only hard part about instalation is the part of the hose that tucks behind the intake manifold by the firewall. just be patient and forcefull and itll budge loose.
heres the part
EDIT: i just noticed you have the 1.8t. im sure that its no more dificult to install>
heres that part
