    A6 TPMS alert too frequent?

    Guest-only advertisement. Register or Log In now!
    Hi all, has anyone had problem with the TPMS alert going off too often? My car says the tires are underinflated once a month or so. And interestingly it's always on the driver's side....I drive alone 99% of the time...is that why??
    Please help this newbie out!
    Thanks in advance!

    Did you reset after you pump air in?

    Since you said it's always on the driver's side I guess you verified that by checking pressure in each tire. Did you had to inflate one or 2 tires? If so, then it's nothing wrong with the system but you have slow leak.

    Honestly that happens to me a lot- when it happens a lot for me is in the change of seasons especially now in this weird season, I donít even know what to call it, overnight itís just around freezing and during the day it gets someone over 90í and thatís usually when it happens to me. Early afternoon like in the middle of no where. For me itís the huge temperature differences I believe. Thatís the pattern Iíve been able to get out of it at least.

    How old is the car, and when did you last change the TMPS sensor, or the battery?

    Both S6 and A6 are 2014. And it happens to both of them so thereís something more than just the sensors themselves. Uhm, earlier this summer when I put new tires on. Iím not sure if the battery was changed then or not but I know the sensors were for sure

    The TPMS on the A6 does not have pressure sensors in the wheels. It works off the ABS system. You should set your tire pressure when they are cold and than reset the TPMS thru the MMI so that it can relearn. This should prevent what is happening in your case. I believe the S6 works the same as the A6, so do the same for the S6.

    Same. I've always reset when they're warm. I'll try and pump air and reset in the morning.
    Thanks.

    It's the 2015 model (bought in September 2014). My car was recently hit pretty badly when it was parked....They put a new wheel in the front driver's side. Nver changed the battery.

    That's actually an interesting observation and I think I kinda agree with you. I think it was less frequent during the summer.

    I always have to inflate both tires on the driver side. The other side is always fine. It's pretty annoying...
    Does that I might need a new tire and/or wheel?

    If you need to keep inflating tires every so often it's mean you have a slow leak and that's it. You might be able to get tires fixed but it takes a really good shop to find and fix this kind of a leak.
    I had that problem on other car and multiple trips to tire shop wouldn't fix it. However it was vehicle with TPMS sensors installed in each wheel and I'm quite sure air was actually leaking thru the sensors.
    There were some rubber gaskets that supposed to be replaced each time tire gets mounted/dismounted. As mentioned earlier newer Audi's (except RS7 - to my knowledge) don't have any TPMS sensors.
    ABS sensor take on this duty as they read wheel revolutions and compare it to set value.
