My DCM PEM FAN error solved

[twiersum]

I've been wrestling with the annoying beep for a few years. After talking to Peter I decided to get new connectors back by the motor. That didn't work. I decided to pull the fan and clean the motor. Once I separated the cover I blew compressed air and it was thicker than a 6.7l diesel rolling coal at a stoplight for a full minute. I can't believe how much carbon came out from such a tiny motor.

Put her back together and reinstalled and error is gone

Was this the original motor/fan or with the dual blower upgrade?

 

[twiersum]

It had the dual blower.

So some questions...
What is the mileage on the car? Higher mileage might explain more dirt...
How about the PEM cleaning frequency and amount of debris?

It's not dirt...it's carbon from the brushes INSIDE the sealed motor. Car has 49k pem & motor clean.
