If there isn't any or much matal shavings on the vanos check valves screen probably is not camshaft ledges. Oil quality and oil flow is huge factor in these engines throwing vanos codes or not. Some say it wouldn't make difference and could harm the engine but I have seen it work. For a DIY-er is $50 for some ATF and good diesel engine oil due to higher detergent quilities built into it. Is definitely a worth of try.

Not that I'm a mechanic but have been around cars all my life practically and I've never heard of this!
TBH I'm dubious I know I wouldnt run it in my N54
There a lot of conjecture on this thread on the use of ATF as a engine flush:
