Help! Crankshaft pulley bolts arnt playing game
Has anyone encountered this problem with thier mk4? The crankshaft 6mm pulley securing bolts are extremely easy to round off. With very little pressure - less than 25Nm they begin to round.
Apparently this is a frequent problem with these bolts, has anyone any ideas/advice/experience ?
Please and thanks!

First, sorry for the late response. I never had a problem with my bolts when messing with the crank pully. I know that my bolts were not that color, which makes me wonder if those are OE, if not I would just get new OE bolts, which should be in better shape. That center bolt is torqued super tight, but if i remember correctly those 4 don’t have to be torqued to a ridiculous spec.
Hope this is still beneficial!
Thanks mate, I actually got them all put eventually was an absolute pain though. Tried a bolt removal tool (easy out), drilled into it and insterted ir but it actually just stripped the easy out and the other didnt move at all! I bought some torx head allen socket things and bashed one into the head of the bolt that didnt budge and eventually stripped it more. I was thinking of having to get a mate to weld on a bolt or something but i thought id guve the torx socket one more try. So with a block hammer i smashed in a (8 mm) socket that eventually was rounding too. I was throughly stumped,though the next time i tried- i cant even explain why but with the longest bar i could fit and all my strength it went 😁. I think they mustve been just mega tight and stuck on there.
Replaced all 4 bolts. Alot of the other bolts on my car the same colour idk if its just mabye the oxidation process? Or a particular type of bolt.
