I would say it is the DCT. However, what is unknown is exactly what is causing the shuddering. The transmission seals are known to have issues and can allow oil to leak from the wet to the dry part of the transmission which contaminates the clutch and causes slipping. However, this is not the only issue with the DCT. For some reason, the shifting can get out of whack due to something that goes wrong with the adaptive learning process. If there doesn't appear to be any oil leaking into your bell housing area, it is more likely this type of issue. To remedy this, you can go through a clutch relearning process which can either be done at the dealer ($$) or using a cheap scan tool and the Forscan software. I'm actually due to do this again myself.
First check for any signs of fluid at the bellhousing interface between the engine and tranny. That's not intended to be an oil tight interface since it is supposed to be dry inside. If you see oil, you have your answer. If not, you could go further and partially remove the bellhousing bolts to open a small gap just to be sure or just go ahead and do the relearn procedure, especially if you're going the Forscan route so it's not costing you a lot to do that.
So today when I went to check my oil and other fluids I noticed something bizarre. Down behind the air box there was a plastic tube connected to a vacuum line type hose that was just sitting around out of place. After looking around I found a hole on top of the DCT where the tube would appear to...
Just want to share my camping mod for the MK3.
Before I just folded the rear seats and then sleep there but it was difficult because you had to move all the gears on the forwarded front seats every time you wanted to sleep.
This is balance between sleeping and storage space.
Hello FF members!
It's been a two year hiatus since I've posted here. I've been busy with other projects.
But anyway, I have time now to work on things that I don't like about the MK3.
I've been successfully sniffing the CANbus either HS,MS,I bus. The later one I could read my multimedia...
