Question no power and no changing over

Hi Guys Help!!
My car E200 Kompressor was just fine
No codes or fault lights
When squeezing pedal very slow reaction
When lifting gas pedal a burrrrrr sound like exhaust. Exhaust no holes
When slowly pushing gas pedal also a burr sound
I have reset idle
I have re learned gearbox many times
QUESTION:
Can it be vacuum related?
Can it be supercharger hoses related?
Can it be catalytic converter choked?
No strange sounds when idle or revving up
Thanks appreciate
Theo

Hello Theo and welcome to the forum! What did you use to pull the codes? Was it a Mercedes-specific scan tool or a generic OBD2 reader? If the car is not getting power, there are likely stored codes that you can pull to give you an idea as to where the issue(s) are coming from.

Hi There
Thanks!!

The car never showed any faults and engine light was off,
I eventually found the problem.
Both Catalytic Converters were nearly 90% blocked.
