It's important to note that on the 1.8T, especially the early ones, even following the factory intervals might not be adequate to protect the engine. Extended drain intervals have lead to engine sludge on Audi, Saab, Toyota, and other products. This was simply a result of companies trying to tout their products as "low maintenance", and cutting out maintenance that was actually necessary. Audi made the same mistake with their timing belts, as many break before the replacement is scheduled.

Bottom line is that changing your oil every 12k, especially on a turbo car, simply won't cut it. Unless they can verify that the oil was changed with synthetic using realistic intervals (I go 5k), pay a little extra for an inspection for sludge.
