Audi TPMS Glitch
This bulletin applies to 2010 Audi Q5, A4, A5 and A5 Cabriolet models. A 44 display in the dash “TPMS Tire pressure system malfunction” may appear. DTC 03543 will likely be stored (low availability) in the ABS/ESP address word 03 (J104).
A software concern causes the low availability counter to reach the threshold for DTC 03543 too quickly.
Integrated in the TPMS control is a counter that tracks system unavailability due to certain driving conditions such as extremely rough roads. A software concern causes the counted value to be overstated with each ignition off cycle.
If a vehicle is driven primarily for short trips at low speeds, and is used infrequently on the highway, the counter may reach the threshold for DTC 03543 because of frequent cycling of the ignition. A customized software is available that was started in production month November 2010.
Update the ABS/ESP module J104, address word 03, using the SVM action code as listed in the table below.
MODEL OLD SOFTWARE NEW SOFTWARE SVM ACTION CODE
A4………….……….. .050 ……………………….. 060 …………………..03A002
A5/A5 CABRIOLET…050 …………………………060 …………………..03A002
Q5…………………… 100 ………………………...110 ………………….. 03S002
