So in your case the diff and transmission do not still have their original fluids, which would in theory be the case with an E90 at that many miles. But perhaps that is another thread.
As for the engine oil, published analysis seems to support a 10K OCI. It is the 18K that the CBS is trying to run the car too that causes concern, and that has produced some weak analysis results.
A cautionary tale is the Audi A4/Passat 1.8T sludge problem. The rest of the world runs these cars to high mileage with no trouble, but here in the United States some combination of crap gas, crap oil and driving patterns turns them into sludge monsters. And it took 6 years for that problem to surface.
A cautious approach to preventative maintenance may not be appropriate for everyone, but those who do so are not "wrong".
