My 2005 Crossfire Roadster has the Check Engine light on but runs great.

· Took to Mercedes Service Shop

· Code showed all 4 Oxygen Sensors active

· Recommended changing right bank upstream and downstream sensors

· Once changed all 4 sensors came back active

· Tech recommended Dealership to replace left bank sensors. If still active it may be the Motor Electronic which they don’t handle. Sensors replaced: 001 540 60 17 79, Sensor and 001 540 50 17 65, Sensor

Since Chrysler dealerships won’t work on Crossfires in Broward County Florida, I have appointment with Mercedes dealership but not hopeful they will work on my car. Any guidance is appreciated…
