CLK230 -00 No throttle response
CLK230K -00
M111.973 engine
Car has been parked since last year so I suspect the battery have been flat and a jump start have been done.
Starts and runs poorly on elevated idle, approx 12-1300rpm
It's very rich so I think it's on some kind of failsafe mode.
Dos not respond to throttle pedal at all.
No logged or active codes when checked with HHT-win
Checked pedal sensor and throttle valve position sensor signals and they are correct both in hht-win and when measured with dmm over the full range of movement.
Throttle valve does not move when attempting to increase or decrease position with actutations in hht-win either.
At key on the valve briefly moves to it's fully closed position and then goes back to the "rest" position.
Throttle motor works in both directions when driven by an external power supply off the car.
Anyone seen this before and have the fix?

I have not heard of this specific before. But I would suggest attempting the throttle reset procedure. Turn key to position 2, but don’t start. Press throttle peddle to floor for 10 seconds. Keep pedal pressed and turn key off. Remove foot from throttle and wait 2 minutes. Then restart.
