about tire pressure sensor
ytd when i went to the tire store to order 17' wheel+winter tire package, i was noticed that possibly there'll be a tire pressure problem(actually it's not a problem)showing on the driving panel due to the sensor detecting there're not originally factory winter equipments. anyone has encountered this similar problem??

sorry, my laptop display isn't big enough for that font size so I can't read your post ;)

Luckily the problem is not as big as your font. Go into the car MMI and select tire pressure monitoring and then do "store current". This will store the current tire pressure and alert you when the pressure drops from this point in the future.

This issue depends on the year of your Q5. 2009s have telemetric sensors integrated to the valve stems that transmit the tire pressure to the computer. If you were to purchase aftermarket wheels for the '09 you would have to purchase additional sensors or disable the system. However on 2010s, and presumably future versions, the TPMS is computed by the same system that monitors the ABS so there are no integrated pressure sensors.

When you make the switch, check the pressure of each tire using an accurate gauge after they're on the vehicle (while cold). Make sure they're all even and to spec, then reset the TPMS through the MMI, as previously stated. You shouldn't get any error messages and no additional electronics to buy.

haha, you're so funny,man! My sales representative told me that the MMI system will be a bit more complicated than ever b4. lol. is it true?

You don't need sensors in the wheels any longer with the new system. I believe Euro and Canadian Q5's always had this system, 2009 US Q5s had the valve-stem sensor system.
From Audi's press release - "The standard-fit second-generation tire pressure monitoring display is a very clever system. A software-only concept, it does not require any wheel-mounted components. By monitoring the tires' vibration it detects a rapid loss of pressure in the event of tire failure and also senses which wheel is affected. The system also notices if all four tires are slowly losing air at an equal rate – this effect, which is caused by diffusion, may amount to up to 0.1 bar per month. The tire pressure monitoring display requires no servicing or consumables such as new batteries." |
Nice post and much more polite than I would have done - Usually on these types of posting I just say RTFM! :)
