LiquiMoly diesel purge

Very interesting results with this stuff. I'm sitting here running a 1l bottle of the stuff through the engine (not added to tank, but run through neat direct to the injectors), and in the 20 mins I've been sat here I've watched as the injection quantity deviation has dropped from an average of 0.70mg/str to about 0.20mg/str. Cyls 1 and 4 were the worst to start with, and these are at about 0.3 (not far from spec of -0,28-+0,28; cyls 2 and 3 are currently hovering around 0.0 - which is obviously the ideal.

Amazing effect this stuff has. And no, I have no connection with the product.

Edit: after using the entire can of the liquid, the idle is more stable (going by the figures in VCDS, anyway). It looks like cyl 1 compensates for cyl 4 (or vice versa), and cyl 2 for cyl 3: the values of each of these pairs add up to 0, +/- a little bit.

....or am I making a fool of myself, and the injection deviation would drop anyway, after half an hour or whatever sat at idle??

Wurth have bought the company and I asked my Wurth rep about their products last week, especially the one supposed to help timing chains. The is also a US product called Hot Shot’s Secret I am interested in for fuel of the Devil injectors but I am struggling buy sensible amounts to play with as our CR TDI loan Passat has an injector wobble.
