How do I reset the tire pressure warning in my Audi A6?

I recently replaced my tires and the tire pressure warning is still on. I've tried checking the pressure and resetting the system, but it's still on. What can I do to resolve this issue?

First, make sure you check the tire pressure in all four tires. If they are all properly inflated and the warning is still on, try resetting the system again. If it still doesn't work, you may need to visit a dealership to have the system checked.

I had the same issue and here's what worked for me: turn the ignition on, press the 'CAR' button on the MMI system, then select 'TPMS' and press the center knob. This will bring up the tire pressure information and you can select 'reset' from there. It should clear the warning.
