Update on S54 EML light and Service engine soon light

3rd time at the dealer..replaced all kinds of parts including:

exhaust camshaft sensor
accelerator potentiometer
pedal potentiaometer

Got it back yesterday..they claim all is well and what do you know...EML light comes on, power is cut in half and throttle feel is slow with some sputtering felt on the pedal.

I am giving them one more chance to fix (4th time) then I am going to seek counsel on Lemon laws...its just no longer fun to drive when you hit the gas and the power is gone. I could have bought a civic if I wanted that feel.

My guess is its the Dinan ECU but that fell on deaf ears at the dealer.
