Review on SCITOO Fit for BMW M52 M52TU M54 M56 Double Vanos Special Camshaft Timing Locking Tool Kit: Enhancing Precision and Efficiency by Troy Henkhaus

The name says it's good for the M52 engine which is single VANOS. All others listed are double VANOS. My VANOS key didn't fit the pinion. I'm not sure if the wrench size changes between single VANOS or double VANOS, but it really annoys me. I had already installed half of the kit when I found out about this. Not sure if you can see the picture but the clearance between the sprocket ring and the pin that sits in the teeth is too small so I couldn't find a grip to turn the sprocket.
