Hi all! My CE light came on a month ago for the code P2753 - Transmission Fluid Cooler Control Circuit/Open and I replaced some parts after reading some posts on the Error code. I scanned the VAG sites for solutions. I replaced everything, but when I cleared the code after doing the work, a couple of days the code popped up again. Does anyone have any other thoughts on what would make the code pop up again? It’s frustrating because I really do’t want to go to the dealership to have this fixed as they charge 1000’s just to fix this issue, which I’ve read. There’s a TSB out fo this issue, but Audi won’t offer to pay a partial cost of the repair if it’s not done by Audi. And there’s no guarantee that they will even pay any portion. I’ve read post that dealership would charge as much as $1700-2000.

Anyone have any tips for anything else to look out for to resolve this P2753 issue?

Are there two valves? N488 and N509 ?
I thought one is under the subframe which sounds like the one you replaced and one is by the after-run pump, but perhaps I am confused.
Also check fuses maybe.

Thanks! I'll check the fuses.

Not sure if there is another solenoid, but hoping this thread can provide some answers. And yes, I replaced the one under the subframe by the drivers side front tire.

Thanks for your reply.

BUMP.

Keeping this post towards the top so that I can get this resolved. Hoping more people can chime in please.

Thanks.

I found this on an online repair information service called Direct Hit. "Code P2753- Transmission cooler valve open circuit. Transmission cooler valve on drivers side frame under heat shield. Check connector for heat damage. Valve is located directly under exhaust pipe, heat shield does not shield connector. Replaced transmission cooler valve, connector, and wires". Hopefully that will help!

This is the only thing I could find in my service manual for that code. I would try poking around with a voltmeter and see if you can find some bad wiring or something.
