Fault Code P0c2d Auxiliary Transmission Fluid Pump Control Module Feedback Signal Low

[Warrior07]

Afternoon guys,

 

Need help understanding this code. Fault Code P0c2d Auxiliary Transmission Fluid Pump Control Module Feedback Signal Low. My understanding the most common issue is low battery. I have since replaced the battery. Code is still up. Anyone run into this and found a solution that worked for them? Auto start/stop not a huge deal for me but want that check engine light to turn off..

 

Thanks in advance for helpful insight,

 

Chris

Have you found any solution yet?  I have the same code reading and have not found anything yet.  The mechanic that I go to feels 80% sure that the transmission fluid pump needs replaced on mine.  I prefer somewhere closer to the 99% sure level before i spend the $$$

 

Thanks

Transmission control module.. let you know if works. Under right seat. Got it for 165 used. Porsche hinted it. I dont think its pump to be honest

Let me know if it works, and where you located it/ or part number if you don't mind.

 

Thanks

I did not get the code but did appear in my BT code reader. My CD is always plugged into a tender when not driven for more than a week.

I haven't fixed this issue on any Porsche, But have on other VAG cars. I have found that there is a plug on the trans wiring harness that's fills with coolant from the solenoid valve and corrodes plugs out and causes a similar fault. I have in the passed replaced the loom, solenoid valve and made a repair to the damaged plug. Might be worth a look into ?? not sure just throwing the idea out there.
