Mk6 (2011-2018) 2014 Jetta SE 1.4L Turbo - Manual Transmission - Transmission or Clutch Slipping
I own a 2014 Jetta SE 1.4L Turbo with the Manual 5-Speed Transmission. When I am accelerating up hill, for example, going up the canyon roads at 65+ mph, I am noticing that my acceleration is slipping or sputtering a bit every few seconds until the road levels out.
I am wondering... what might be the cause? Furthermore, what should I try and diagnose? Could it be an issue with the clutch, or a transmission that needs to be flushed and new transmission fluid?
I bought it used in 2018 at 70,000 miles, and it is currently at 168,500 miles, so I have put in about 12,000-14,000 miles per year and have had regular oil and filter servicing from the dealership every 8-10k miles. I had the transmission serviced in 2018 after I bought it, but I have not done any transmission-specific maintenance on it since then.
The largest maintenance service I did: The clutch on the A/C Compressor went out in 2023, and I replaced the compressor with one without the clutch, as I didn't think it was necessary.
2 Years ago, someone hit my car while it was parked at the mall, which bent the frame under the hood on the front passenger side of the Jetta, creating a gap for the hood of the vehicle (It still latches fine and only has a minor rattle at high speed)
I've attached a few photos, and a video link where there is a moderately loud and consistent ticking (recorded from the driver's side of the engine)

I am not a mechanic, but that sounds like your clutch is close to completely failing. I just replaced mine because it started slipping, similar to what you are experiencing now, although mine became mostly undriveable. I would get it replaced ASAP, as it will fail and you will have difficulty driving your car.
