For future individuals who stumble onto this thread. The 1.8t is absolutely an interference engine. Very expensive and you will have some valves bent 100% of the time usually 80-100% of the valves being damaged. Head will likely need to be replaced not rebuilt if a timing belt breaks in the 1.8t. The 2.0 petrol is also interference but people sometimes get lucky and have no damage when a timing belt breaks. Most of the time they are also damaged.
