Hey there - Got a durametric (mostly for my RS and cayenne...) but it also reads codes for the 964 out of the alarm, engine, and ccu modules.

when pulling codes i am getting:
15 - rear blower motor temp sensor - yeah ok i don't have it installed
42 - oil cooler blower motor
32 right mixing flap motor


Let's start with 32:
All my servos are working and moving correctly and in full motion / speed.
First, which one is 'right' is it as you face out the front windshield or facing the servos from the frunk? stupid question no?
second - what can cause this error even though the servo is working?

Now on 42 -
i've suspected my cooler may NOT be working as i've never heard it or felt it, but i've also not gotten the car very hot never to the 2nd line.

is the best test plan here to first check the fan will operate, i think there is a relay jumper you can jump, check resistance on the resistor, etc? i think i saw a decent debugging plan here but if anyone has a pointer...

Thanks

ToreB has a great DIY section for troubleshooting CCU error codes.

Oil cooler & AC fans = http://www.bergvillfx.com/fanresistor

Good luck with the repair.

Thanks Rob..
It is not uncommon to have fault codes on the CCU servos. The servos might have hiccups causing faults from time to time. I would clear the code, and see if it reappears. If so, change the servo in question. Left and right is as seen sitting in the seats.
Cheers,
Tore

Weird, I replaced the servo just recently (right) and it's working correctly. That servo is new... I guess I'll just let it be for now.
