I bought a brand new manual transmission '10 Jetta TDI sedan back in December. I currently have 5K miles on it and have followed all of the suggested break in techniques. A few hundred miles ago I started getting a slipping while in third gear. It doesn't happen all of the time, but it is very pronounced when it does. It occurs during both moderate and heavy acceleration. Every other gear is fine. My first thought was the clutch slipping, but its brand new and I've been driving stick for a long time so I doubt I destroyed it that quickly. (This is my first diesel, so I'm new to the mechanical side of diesel cars). I'm assuming they don't have a cap and rotor so that can't be it. No spark plugs, so thats out.
Whats happening here?
