Default 2.0T Coolant Leak. Plastic hose coupling flange on back of engine replaced.

The dealer said that they have seen this problem a number of times and that the part they are installing is the same design as the one that failed. Have others on this forum experienced this problem? There was one thread earlier on this topic but with only a couple of replies. I'm interested in the frequency this is occurring.

Default Same problem. Replaced at the 25K dealer visit. `

Many others have had the same issue. It is apparently common on B6 1.8Ts as well.

BTW, my leak was very small. Only noticed after removing belly pan to inspect prior to dealer visit.

Default Yup, it is common on the 1.8Ts. There was a TSB issued for it, my flange failed last winter

and lost all my coolant. Car was towed to dealer to get that flange replaced.

Is there somewhere I can find the TSBs online? I'm leaking, too, and I want to have it in hand when i hit the dealer. TIA
