Oh, you are talking about the airflow meter potentiometer. I thought you were speaking of the pot inside the ETA, which is not replaceable. Do you have any info. only the adjustable camshaft timing solenoid circuit being open, of course I realize any or all of these problems could be related to something small that is seemingly unrelated. I hope to get to the bottom of this soon, as I miss driving the car.

I will post pictures later for all you 500E fans.

Thanks,

Bill
