There are a vast range of these, from £160 to £10

Considering what they do which is not particularly strenuous, and likely to be used once or twice, What's wrong with the cheaper ones? 

That looks like the one I used on my old Roomster 1.9 PD engine. I wrote a guide on that task in the Roomster Guides area.

That's the correct one for your engine is it ?

I only had a cheap one and never had any issues.

You only actually need the crankshaft locking bit, the bit with the wide black rectangular geared curve on it. The top camshaft lock pin a 6mm drill bit will suffice too. Similar with the aux belt tensioner.

Thanks🙂

The depicted ones are for 1.9tdi PD and 1.6/2.0 CR engine ea 189. Also vag has come up with a new set for 1.6/2.0tdi cr engine code ea288. I have both sets. The depicted one (one of them) meant for the 1.6/2.0 tdi cr ea189 engine will also be useful for the ea288 engine. The new set specifically designed for the ea288 is just a little better or one could argue it to be more practical. The former is way cheaper than the latter. The 1.9tdi pd crank locking tool will not be suitable for the cr engines. If I remember correctly the pd tool has its arrow mark on the tools wave top while the cr one (fits both ea189 cr and ea288 cr) has its arrow mark on the wave bottom.
