Is VW tool #3391 the correct tool for locking our camshafts for timing belt replacement?

in the service manual, it states that you should remove the cam lock tool to remove the pulleys, while removing the pulley's is a good idea (at least loosening them before installing a new belt), I'd recommend keeping the cam lock tool on the cam's while you remove and reinstall the pulley's.

Do you know what special tools are needed to complete a timing belt service?

...The cam lock tool (#3391), the cam pulley puller (#T40001), the timing belt tensioner lock tool (#T40011), and the crank lock tool (#3242).

I had issues using the crank lock tool, so I made my own version. The crank lock tool does have the right thread pitch, but it seems to bottom out before the drift is in the crank hole. I just made my own crank lock tool.

As for the cam pulley puller, I purchased this along with the cam lock tool, but I'm sure you could get away with using a properly sized gear puller.

As for the timing belt tensioner lock tool, a simple 2mm allen key works great, or any strong small metal pin. The special tool is just correctly sized and has a nice ring handle on it, but you can get away with a lot of things to lock the timing belt tensioner.
