Right,
I checked last week. For drivers who use their right foot.
1st change on cambelt for the 180 turbo is any time on 40K, Same advice also for the AUM 150 unit, and certainly before 50K. Next change before 60K. By the time you get to 100k you must have had three new cambelts, or going for the third straight away.
If you drive routinely, then a 10% longer interval on the 1st change, next change though, before 100k. Don't take totally unecessary risks with your turbo unit. If the belt splits or comes off - your looking at a rebuild from the block up, and it may never run quite so sweetly.
