I have a 2000 passat 1.8t I have to replace the head mine is a ATW I found one at my local junk yard that is a AEB I already started pulling it today I plan to go back tomorrow and pull it and purchase it so I'm wondering if I buy it can I slap it on there and run it or will it not work? I called VW dealers/mechanics and they can't help if it wont work I wont buy it
