[IIS Tire pressure: malfunction! See owner's
manual
If the [JJM indicator light appears after switching
the ignition on or while driving and the J indi-
cator light also blinks for approximately one mi-
nute and then stays on, then there is system mal-
function. The following are examples of situa-
tions that could cause a malfunction:
- If the message appears at the end of the adap-
tation phase, the system may not detect one or
several of the wheel sensors necessary for pres-
sure monitoring. This may result from one or
more wheels without wheel sensors or with in-
compatible wheel sensors being installed.
—Awheel sensor or another component has
failed.
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains.
~The tire pressure monitoring system is not
available due to a malfunction.
— Transmitters with the same frequency, such as
headphones or remote controlled devices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
The [indicator light and the message turn off
'once the tire pressure monitoring system is avail-
able again. If you cannot correct the malfunction
and the [MIM indicator light stays on, drive imme-
diately to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
repaired.
