Avant TPMS antenna and control module location?

[bcristea]

Hi,

I have a 2008 S4 Avant and my TPMS warning light is always on and all tire pressures (including spare) are good and sensors are transmitting (checked at local tire shop).

My next plan was to check the antenna and control module but I have not found where they are located for the Avant?

If anybody knows please let me know,

Thanks,

Brian

Stupid question but did you air/check the tires while they were cold?

I ask as I did this while they were warm and the light didn't turn off, filled/checked while cold to recommended pressure and it turned off.

I checked them both cold and warm but still have the issue. The flat tire light is on plus the display says TPMS. Normally if a tire is low on pressure the flat tire light just comes one. I think I found the antenna, it looks like its connected to the rear bumper beam with a plastic bracket. I'm going to check that.

I would still like find out where the control module is located.

If a spare wheel was rotated in the system must be reset to tune in to the new wheel, per the manual. If thats not the issue i would pm 65vette, or jimmybones they both have been all over these cars.
