Both Vanos Bad ?

I know a slight breach of protocall, but I was looking for some quick answers, so I will post first, and also spend the morning researching old threads.

My beast (MY2000 with 85K miles) idling poorly, and running a bit off. I was thinking perhaps CPS or perhaps secondary air system issues (just replaced 2 of those and MAF's a few months back).

The stealership says both Vanos units are bad. Now what is the probability of this, and what other single problem could cause them to reach this conclusion.

Thanks in advance,
