2010 Audi S5, low tire pressure message & symbol, but no TPM settings on MMI ??!!!?!

Ok im really confused. I just bought a 2010 S5 and im pretty sure the light wasnt on when I got it. We have a lot of cars between home and work and I switch cars a lot so I dont pay too close of attention to things anymore but im almost positive it wasnt on before. So now i start the car, get the message that I have low tire pressure and the symbol is on on the cluster. I check the tire pressures and adjust them all. Get in the car, and drive. thought it might go out on its own. Next stop, back in start, same messages. Go into the Car settings on MMI, to my dismay, no Tire Pressure Monitor selection. Back out, check all other menus in case they moved it, nope. Just not there at all.....what the?????? Looking at the valve stems, all metal all the way around so it must have tpms. warning light on the dash... How the hell do you reset it ??? how can it not have the menu on the Car setting on MMI... HELP?!!!!!

MMI setting under Car should have it listed as long as you are in park. Press once to store new values, then again to confirm.

Nope. Tried it car running, car not running. still not there..

Just a guess but I wonder if it is due to a dead battery in one of the sensors. They are due--- https://auditpms.wordpress.com/2012/03/13/oe-tpms-life-expectancy/

BUT-- Do 2010 cars HAVE sensors? Our 2011 Q7 does not. It works off tire rotation discrepancies.

Mr Patterson may well be right.... (like your books by the way)

Switch from abs monitors to in wheel tpms was market dependent.

I though that B8s had sensors in the wheel and B8.5s went to measuring rotation ratios.

B8s are using measuring rotation ratios. So when you check the pressure you need to drive 5-10km until the system resets itself. But you must have the menu in the MMI ... that's odd.

Ive tried a little bit of everything. I have driven it much more than 10km, although not in any particular menu since there is NO TIRE PRESSURE menu on my Car settings which is very odd. So when they when to rotational measurement, did they eliminate the TPM menu from the MMI altogether or should it still be there??

congo · Mar 28, 2016

No the TPM menu is there but very limited.
You can see how it looks here AudiEnthusiasts TPMS
Basically it's just a menu that let you reset/set the current conditions. It will then learn it's self over around 5 km monitoring the speed of each wheel.
Pretty much that's it. Only basic functionality ... enough for run flat tires though.

if your car definitively has TMPS, it should be in the MMI menu.
if it is not in the menu, it can accidentally be switch off when VCDS-changes were made.
so, you will need someone with a cable to check this.
