Anyone know if there's going to be a recall for the 2.0 TSI timing chain tensioner failure?

I see there's now an 'official' TSB on the 2.0 TSI timing belt tensioner failure specifically for the Tiguan. Anyone know if there's going to be a recall for this? (derived from TSB 2028302/4 on the 1.4 TSI engine). I've read a couple of people on the forums who've had this happen to them and while I was in Europe over the weekend, a couple of car mags over there had more info on it too. Apparently it's a perfect storm of a badly manufactured part, measured badly, installed badly and checked badly after installation (AutoBild, literal translation)

You've got to be kidding me. I thought the whole idea of a chain was to prevent something like this which was an issue in the engines with belts.

Chains stretch - ask anyone with a motorbike. The tensioner is there to take up the slack and it seems in this case, the retaining pin eventually fails, the tensioner snaps out of position and the chain jumps the sprocket on one of the cams. First sign: difficult starting or unusually clattery engine when running. Second sign (after the valves are all bent): engine won't start.
VWoA have (apparently) replaced destroyed engines that have had this happen - there's a couple of reports of that on VWVortex and elsewhere, mostly to do with Golfs to this point. VWoA seem to be taking these isolated cases seriously though - forum reports indicate that they've sent techs out directly to the dealerships and not let the dealers do anything to the engines.
This is the original AutoBild article from back in March reporting 61 destroyed engines in Tiguans, Tourans and Golf 1.4TSIs but it also affects the 2.0TSI: http://www.autobild.de/artikel/vw-1....n-2892135.html
The first October issue is the one I read that had more info on the 2.0TSI problems but they've not put the online version up yet - I don't think AutoBild do that until a while after the print version is out : http://www.autobild.de/artikel/auto-...2-1944688.html

I wonder if this happend to a modded Tiguan, knowing no modded would cause the pin to fail, if VWoA would still replaced the engine?

It has happened on a modded GTI (golfmk6.com lowerthanzimmy) and they replaced it under warranty. Don't tell TIGSEL......

Glad they are stepping up to the plate, but it somewhat annoys me since they did jack **** for the issues with the earlier 2.5.
