I posted the issue I was encountering on AZ awhile back and came to the conclusion that my motor mounts were going. However, I Vagcom'd the car this weekend and it showed no faults in the motor mounts. I have never received any CEL codes and the diagnostics I did this weekend showed no issues with the car.
The issue I am having occurs occasionally and consists of strong vibrations throughout all gears while under load. The odd part is the intermittent nature... I cannot force the problem to occur but it appears to happen most when I am downshifting hard. To get the vibrations to stop, I can drive from a stop, upshift at 2k and baby the car for a few miles and itís gone. Once the vibrations are gone, I can drive the car through redline (all gears) and not have any issues. I can also downshift hard a few times and not have the issue occur. It seems so random??
When the clutch is disengaged the vibrations stop and reengaged they appear again. So I have eliminated the chance that it was a suspension or wheel/tire issue. The car does not seem to lose power while the vibrations are taking place and I can still drive the car hard. The vibrations are most intense in the lower gears and mellow out a bit in 6th gear. This issue has been occurring on and off for about two months, probably five times total.
My thought is the clutch/flywheel is not engaging correctly when down shifting hard and the vibrations are due to the improper engagement?
What would a broken bearing on the flywheel feel like?
Any advice is appreciated as I have been bugging out about this issue. I canít afford to replace a transmission.
Anyone in NoVa want to take a ride sometime this week to see if we can initiate this issue and try to figure it out?
