What does YOUR dct equipped focus sound like running?
I have a theory why my dct may be so poor after about 30mins of driving. A lot of the grinding, shuddering, etc seems to surface as a result of heat. It doesn't matter if its straight highway or in traffic. Since the overheat message on the in car display is derived from an algorithm of operating parameters and not an actual sensor, the following could explain why I get severe typically heat related behavior without any overheat message...
I've noticed from other focuses driving around that most have some degree of a dry bearing like high pitched noise at idle/low speed. Kind of like a constant minor squeaky belt sort of noise but clearly more in a bearing sort of way if you don't know what I mean. Mine seems to be a good bit louder/more pronounced then others I hear. I'm starting to wonder if this is a throw out or some other similar bearing in the transmission close to or on the clutch pack that is possibly under greased if not bad. If you think about it, a bad or under lubed bearing that is that audible is probably generating a good bit of heat...which either on or near the clutch pack would cause a lot of that heat to get absorbed by the clutches. Since the overheat message is derived from algorithm vs sensors, anything not working correctly like bad/binding/etc parts is not accounted for, so while the algorithm thinks everything is fine based on driving conditions, it in fact may not be. Anyhow I'm thinking something along those lines may be the culprit on mine. Haven't had time to take it in yet. That will probably be coming in a couple weeks.
