Did the timing belt and water pump on an '03 Beetle 1.9 TDI (ALH) and peeked inside while I was at it. Currently at 267,000 mi., it's been running Schaeffer's since around 120K - first syn blend 15w40, but for the last 2 years or so full syn 5w40 with a 10K OCI and mostly highway driving. Hard to get it cleaner, I'd say.
