Hi,

Anybody knows what fault code 02245 means?
Is the reciever module (T91) for remote control defect?
I am not able to start the aux heater thru the remote.

Post an auto-scan please because many things are reactionary and dependent on firmware versions of modules, adaption of antenna, glow circuit or fuel levels ..... etc.

02245 - Connection; RF Remote Control

Check antenna and COM issues?

Voltage issue......or remote battery?

Hi,
Did you fix this. Had the same problem on my A6, had to change an adopt from 0 to 1 under Aux heater I believe, and then clear fault codes. Worked fine (for a while, fault came back), but Im gonna faultfind more when I get home. When I get home I can find the correct procedure, if not someone else here dig it out for you.

Quite sure I used this one though:
02251 - Heater Unit Locked
-> When found in Aux Heater module of Audi A4 (8K), Audi A5 (8T), Audi Q5 (8R), Audi A6 (4F), Audi A6 (4G), Audi A7 (4G) or Audi A8 (4H), unlock heater module by saving a 1 in Adaptation Channel 042, then clear fault codes.


I am quite new to Audi, and faultfinding with VCDS, but as I said, I got mine to work again, even only for a few days.

I have the same fault code 02245.

Tested with new antenna, new remote, T91 module + remote from another similar car.

Battery in car is okay.

Also tested to unlock heater first

Someone have the solution on this?

On Caddy from 2016>, is it security access to adapt remote to car? I can't figure out why remote not work.
