I'm changing the rear brakes on my 06 Passat. (Thanks for the great DIY on this topic) Pulling off the calipers was no problem but removing the carrier to get the disk off looks like it requires a 12 point triple square (ZXN) driver. The biggest one I had on hand was 12mm, to small. I measured it with my calipers and it looks like 13mm. I checked Mac tools and Amazon web sites as well as NAPA and other local places. Looks like all I can find is 12mm and 14mm.
Am I missing something here or do I need a tool made out of un-obtain-ium??
Have the battery charger and VAG-COM already and would hate to bail out to the dealer over a $8 driver.
