I got my 22 Tiguan in April 2022; for two months, I put up with this. Having owned another brand of car, it came to me to do a Transmission Reset. I tried it on the Tiguan, and it seems to have fixed the problem for now. Suggest you give it a try. It works on almost every brand of car with auto transmission. It reset the pedal position in the ECU and transmission.
To do reset
With the car warmed up, and the engine turned off.
1. Depress the Start/Stop button without the foot on the brake pedal. The car does not start but is in the run setting. All the lights on the dash will light up.
2. Depress the gas pedal all the way to the floor until you hear and feel a click like going into passing gear. Hold the pedal all the way down for 20 to 30 seconds.
3. Depress the Start/Stop button as if turning off the engine.
4. Remove the foot from the gas pedal.
5. Wait for 2 to 5 minutes, start the engine, and go for a drive.
If the car does not have the Start/Stop button turn the keyed switch to position 2.
Some people do this every few months. Your driving pattern might change. Relearn your driving style.
Please, after trying this, give feedback if it worked for you.
