I did think that to begin with. But it seems to have a little more go in it after 100 miles when warm on motorway but id have thought clutch wise it would get worse if anything because of heat. It was not worse in any gear it was constant throughout drive. It's does not have the tell tale signs or sounds ect though mate otherwise I agree that would be my first idea it seems to be more of a "bogging down" issue. I'll no doubt replace clutch shortly anyway but I'm sure its along the lines of poss metering unit or possible pipe faults? Thanks though !!!!
