Hi all, long time listener, first time caller. I received 'TPMS Malfunction' in the MMI and now have 03543 - Mechanical Malfunction in Suspension permanently stored in Tire Pressure II. Full autoscan is below. After clearing only the steering wheel (expected, I swapped to a flat bottom!) and 03543 return. All tire pressures are correct. I am aware of a TSB which references this error stored in the ABS module but I'm not sure this is the same. I was thinking about pulling the battery cable then going on a long drive as a next step but I'm wondering what sort of hardware issue might cause this code. Thanks in advance for any suggestions.

Hmm.. I'm not sure what to make of that since this car doesn't appear to have any kind of active suspension.

Maybe different tires, tires are out of balance or defective shock absorbers, so tires are jumping.

This A6 C6 seems to have a discrete TPMS module with sensors attached to the rim valve stems? The physical pressures may be right but what pressures does the TPMS see?

Following up here, thanks for the suggestions all. This vehicle uses an indirect TPMS system that monitors wheel speed sensors to determine tire pressure. There are no TPMS sensors in the car. A similar TSB on the A5, A4, and other models suggested that short trips over rough roads may send the system below the 'availability threshold' for the TPMS module. My simplistic understanding is that this driving pattern throws off the aggregate wheel speed data used to calculate tire pressure.

For anyone with an A6 reading this thread and experiencing similar symptoms, a long drive on a smooth highway followed by an ignition cycle finally cleared the DTC. Thanks again all.
