Just to satisfy everyones curiosity................ I have got the kit coming from DMGRS next week and am in the process of stripping down. I am at the point where I need to take off the aux belt idle roller by removing the T55 Torx bolt.
The Torx bit I have will not fit on when attached to the ratchet spanner as it hits the bulkhead - I was just asking what others have done. Then I realised that I just needed to buy a T55 spanner and all would be well. See.... told you it was a stupid question
