Thanks, you might be right, but I guess the first thing a service center does is trying to fix it in the debug menu, so why not try that myself first?

You could very well be right there! To mechanically adjust is a time consuming business!

But it is the only proper way, the in camera software correction introduces variation in amount needed between optically different lens designs, the more the general amount needed, the more varation there will be. When the AF sensor is properly aligned, it is like magic, most lenses suddenly need 0 adjustment. Yes, it is time consuming, and that is why manufacturers prefer to put AF microadjust in menu and be less vigilant about aligning it properly in first place (during manufacture).
