greeting.  I have a Karoq 1.5 tsi 2019 with 85,000 km and today I cleaned the carbon buildup on the intake.  I cleaned 3 intakes and the fourth remained.  I was thinking of turning the crankshaft pulley to close that valve, but I didn't have that key.  maybe it's a 23 mm 12 angle wrench or something special.  alternatively, I wanted to turn the engine a little by putting the manual transmission in 4th gear, but turning the wheel that was on my jack and the support, the engine did not turn.  as if it is in reverse, with a little more resistance, as if the clutch is slipping.  I tried all speeds and the same thing, the clutch works when pressed.  but I didn't touch anything with the clutch, it works normally, yesterday I came home from work and this morning I lifted one wheel in the air and put a support so that I can remove the engine protection from below.  before that I unlocked the car, pulled the manual (electric) and disconnected the battery.  maybe it doesn't work if the battery is not connected or similar?

I dont really understand a lot of what you were trying to say but you will struggle to turn the engine in the way that you describe because even in direct top gear you the torque you are applying is reduced by the final drive ratio, somewhere in the order of one third, in the lower gears as little as one tenth.

 

Be very carefull about turning the TSi engine in a reverse direction as this can cause the timing chain to jump on start up and wreck the engine, dont be tempted to turn the engine back if you have gone too far and dont try your wheel trick in reverse gear.

 

You would have more success pushing the car forwards in top gear, you still have the torque reduction but can apply more force pushing from a standing position that rotating your arms, also you can bump the car to use the inertia.

 

The easiest thing would be to remove the spark plugs.

I did push forward. My engine have belt. I didnt turn it too much, finally i found some tool to rotate bolt on crankshaft clockwise.

Sorry it was late i was exhausted and used google translate.
