VW Taos Idle Vibration Points to Failed Engine Mount

Had nearly identical symptoms with a 2019 Tiguan, severe vibration issues at idle that got worse over time. Initially thought it was something minor, but diagnostic showed a motor mount failure on the passenger side. The rubber isolator had completely separated from the metal bracket. The shaking you describe matches classic mount failure symptoms, especially the increased vibration in park. These mounts are engineered to dampen engine movement, so when they fail, you get direct transfer of engine vibration to the frame. During the repair on my vehicle, the mechanic showed me the deteriorated mount, the rubber was cracked and oil-soaked. The vibration was severe enough that it started affecting nearby components, including some electrical connections. Once replaced, the engine ran smooth again with no codes. Given your mileage and symptoms, the diagnosis of a defective engine mount sounds accurate. This is a fairly serious issue that should be addressed promptly, as failed mounts can lead to additional component damage if left unfixed.

Thanks for sharing your experience with the Tiguan mount failure. My situation with the VW Taos was pretty similar to yours, and the replacement of the transmission mount fixed the vibration completely. The rubber mount was totally shot, just like you described. Did you remember roughly what the repair ended up costing you? Also curious if you had any other issues pop up that might have been related to the bad engine mount before you got it fixed? I am still monitoring mine since the repair, but so far everything feels solid and those annoying vibrations are gone. Makes such a difference having properly functioning mounts.

Thanks for the follow-up. After seeing the mechanic, the engine mount defective was fixed for 95€, which covered repairing a faulty cable connection that was causing additional issues. The vibration issues completely disappeared after the repair. Before getting it fixed, I noticed the excessive shaking had started affecting other components. The constant motor mount failure induced vibrations caused some electrical connectors to work loose, triggering those engine codes you mentioned. The transmission mount was also showing early signs of wear from compensating for the failed engine mount. The repair was definitely worth it, going from that harsh idle shake to smooth operation made a huge difference. Keep monitoring your mounts during regular maintenance since they do wear over time. Getting ahead of mount failure early can prevent damage to surrounding components and save money in the long run.

After reading about similar mount failure issues, I took my Taos to a certified mechanic. The inspection confirmed a completely deteriorated transmission mount, the rubber was cracked and separated from the mounting bracket just like others described. The repair cost came to 450€ including parts and labor. Once the new mount was installed, the difference was immediate. No more shaking at idle, engine codes cleared up, and the whole car feels more solid. The mechanic showed me the old mount and it was in worse shape than I expected. The only other issue that popped up before the repair was an occasional rattling from the engine bay during cold starts. That disappeared completely after fixing the failed mount. Really glad I got it taken care of before it could cause additional problems. Looking back, I should have trusted the initial diagnosis. The symptoms matched perfectly with a bad mount and getting it fixed saved me from potential bigger issues down the road.
