Arthur,
Ummm did not see the e-mail. The procedure I used was to turn the key to "ON" and then depress button next to the LED on the diagnostic terminal for three seconds and release. Flashes 2 times. Repeat the 3 sec. depression with release. Then 3 flashes. Repeat button depression. Then 17 flashes. Do it again and the codes start over again.

From an on-line source my codes are but are for a cabriolet in the same year

code 2 = heated O2 sensor inoperative
code 3 = Lambda control inoperative
code 17 = CAN data exchange-malfunction between control units

could be bad info?

Gilly the noises I hear are much louder than what I would consider a "soft buzz" It is a predominant "click" that is rapid and erratic that is happening inside the throttle actuator. And the relay clicking sound in the cabin
