$2200 doesn't seem far off if it was a 'dealer' workshop.
It is pretty close to the quote I have received from Qualitat for 2.0 TSI engine.
Are 1.4 Chain/Tensioner known to stretch/fail as well? the internet seems all rage about 2.0s, but didn't see much regarding 1.4 issues.
Quick logic brings me that they would be using same parts for TSI engines of the same era, but then again, what do I know.
