Not all 2008 to 2010 common rail are going to be 77mm , some are an ok oem 100mm , sometimes they can tell you which , sometimes you need to drop the sump and withdraw the key to find out .
That sounds like plan Gazwould....replace both the keyway, and key. I presume that the chain drives have long been consigned to the rubbish bin ??? Would make good sense at the moment to import a good spec A6 from England, so I will wait for a few month's into the new year, and see what is on offer then. To be able to positively identify one which had the 100mm shaft would be the icing on the cake.. LOL
Thanks again Gazwould,
