Took the car for an oil change (non VW dealer) a few weeks back and about a week after the car started experiencing some vibrating/shaking from, I assume, the engine. This only occurs when the car is idling or at very low speeds.
It wasn't a typical shaking from side to side that you'd experience from most engines. The car was jumping front to back. It almost felt like stalling a manual transmission car. The revs jump slightly, about 100-200 rpm. It feels like the car wants to lurch forward and break free of the brakes. Now on some days this isn't a problem and on other days it's an issue.
Engine noise is a bit louder than usual. Sounds like the belts or the fan, but nothing is lose and the fan is working.
I don't feel like all the power is there either, especially in lower gears and on take offs.
Ran the diagnostics, it didn't bring up anything other than some issues with the spark plugs and the coils. They were replaced but nothing changed with the problems. I have noticed oil level drop but there are no oil leaks anywhere.
I appreciate if anyone can help me. The car is not under warranty and the VW dealerships near me are extremely poor.
