I already swapped out the trailer module (rear right trunk/side aread), no change. 4E0 907 383 J SW: 0100 HW: H09
Note: right cooling fan kept running for long time after shutting off, locking car (see engine code, NOT the normal 'hot engine afterrun'). Ordered module, but then problem went away (not scanned since).

What and where IS "Terminal 30"?

Prodigy braker controller installed, worked great for a year, now erratic, not working most of the time, only very weak braking.
Code coming back after erase (need to check if right away or when using trailer).

Additional note after I found this post somewhere (below):

All other faults did not come back except these: the 'cooling fan keeps running' issue only occured months after the trailer brake issues started.


4528 - Coolant Fan Control Circuit 2
P0481 00 [047] - Electrical Malfunction

1 Fault Found:
02539 - Terminal 30 from Control Module
014 - Defective

I took the car to Audi Service and they told that the first error with the cooling fans is related to the second error (Trailer error). They told me not to worry about it, but after 4 weeks of visiting Audi, I got a yellow symbol showing an unlocked padlock and a two bar in my dashboard and it will not go away. Any idea on how to solve the error 02539 - Terminal 30 from Control Module - 014 - Defective, please? Do I need to replace the module 8K0 907 383 C or is it a wiring problem? The module itself makes a continuous whining sound (similar to an electrical fuel pump) when I switch off the engine and after 2 minutes it stops.

Un-switched battery power.

-Uwe-
And how can "terminal 30" be "defective"? Where on the "Control Module" is Terminal 30? I suspect it might not be a defective 'terminal 30 from control module' but rather something on the car side leading to (or providing the module with) "un-switched battery power"? Assumption based on switching modules and getting the same code/issues. Unless those "trailer modules" are known to be bad all the time.

If the wiring and/or fuse between the battery and the module is faulty.
That's one way. But I think in this case, the trailer module monitors the current on the un-switched power its supplying to the trailer connector and might report this kind of fault if there's an issue with the wiring to the trailer, or even in the trailer, if one is connected.

In the diagram, would T4y/2 be the 'termin 30' "4 pin connector, black, brake booster" (not sure what a brake booster is, but assume trailer module?).

So should I splice a Ampere meter into the "un-switched" power line at the trailer? Which pin of the 7 pin connector is that 'un switched' power? #2 Trailer Brakes? #4 Aux 12V/Charging (often not working on Audi, mine has no power). All others are switched.

Your scan isn't posted properly. Look up the how to on posting autoscan.

How else but copy and paste can i post? what is missing/wrong. Are you looking at the original post? From top of scan to bottom? There is nothing else to in the scan (after using 'copy' after full VAGcom scan and the paste).
Fixed the link seems to work now: https://drive.google.com/file/d/1xmC1l3MnsArD5IKfAMf__aLIGULI9vJA/view
I don't seen nothing on the dash that is why I am showing you anything :-)

So 'permanent' 12V may be the issue. Either to the control module (which connector/pin?) or to the trailer (where is trailer getting permanent 12V from), from FROM the control module (which connector/pin) to the trailer ("monitoring draw").

with "terminal 30 defective" could it be 'fuse S87' in attached diagram ("trailer towing attachment thermal fuse")? Where is S87 located in the Q7?
I assume J345 "Trailer detector control module' is the towing module 4E0 907 383 J ?

This diag should be simple: disconnect trailer, measure all power and grounds at the module input, with a test lamp, delete faultcodes, measure output power and ground at the outputs. Nothing more nothing less. No output? Bad module.

Which pin? Check wiring diagrams, buy them from erwin, not expensive I heard, or just measure the big fat red wires in the module input.

I am afraid not much can be tested (output side) with no trailer attached. And what is the pin out of the module and what should the respective inputs outputs be under what conditions?
From a mathematical standpoint: modules rarely fail. Replaced module already, chances are slim that module is causing issue. The E brake does fully work SOMETIMES, most of the time only 4-5V output to trailer brakes.
You do understand that the E brake signal is NOT an 'on/off' ('test lamp') signal?

What I do understand is that I will not buy the wiring diagram just to hand it over to you. You understand the schematics are not for free from erwin, do you? Or don't?
