My '06 Jetta with 165K miles has a developed a pronounced wobble at low speeds, and vibration / alignment problem (pulls to the left) pretty bad at higher speeds over the past year. So I'm thinking bad bearings or CV joints?
It also sounds like the flywheel is going bad; it sounds like a bunch of loose change flying around inside the motor right after I start it (goes away after it warms up).
So my thought is to schedule it for a flywheel replacement. They have to pull apart the drivetrain and suspension to get at the transmission anyway, so why not roll it all into one job, replace bearings/CV joints/etc. at the same time and save labor, right?
The only engine problems I'm having at the moment seems to be an occasional loss of prime on the fuel system- sometimes on the first crank it will hit real hard (almost like a backfire) and stop. Then when I try to crank it again it takes a long time of cranking (almost until the battery is dead) before it finally fires up again. Other than that, it runs fine, and I get around 38 mpg city driving, 45 on the hwy, no loss of power, it'll get up and go (smokes like a dump truck when it does, though).
What causes the loss of prime on the fuel system? Maybe one cylinder fires while the injector is still open and blows the fuel out of the fuel line? Camshaft or timing issue? The timing belt was last changed at 105K miles, and the next time I change it, I think I'm going to put in a new cam whether it needs it or not (maybe even a Colt stage 2.)
