Problem in my 2003 C230 Kompressor
Hi
I need your advice of what could be the cause and what I should do
The problem is that sometimes I realize poor acceleration and many times it seems like the car is stuck on one gear for more than 3 seconds (while pressing the pedal), then it seems that it changes 2 gear at a time,
and also when slowing down.
I took it to the Mercedes Dealer, said nothing wrong
later on I took it to a good mercedes mechanic -- nothing
another one and nothing
I bought a OBD2 scanner and found these errors:
P0120 - Powertrain: Throttle/ pedal position sensor/ switch a current
P2009 - Powertrain: Intake manf runner control circuit low bank1 a)
P201C - Powertrain
P2004 - Powertrain: Intake manf runner control stuck open bank1 a)
Thank you for your help

UPDATE
Update: I erased the fault codes then drove for about 10 miles
rescanned ---> no faults
symptoms are still felt
I made some scans that I will upload:
1- test on idle:
2- test on track 5% slope upwards:
3- test on same slope but downwards:

From the readouts it looks like a couple things.
The TPS threw a code at some point, but it sounds like the
tranny is the thing giving you pause.
Have you ever done a complete fluid flush?
Assuming you have an AT yes?
Perhaps time to do some tranny maint, and check to make sure there's no oil in the TCU
under the passenger footrest.
