Tire Pressure

Did you reset the MMI tire pressure alarm-window? You need to do this whenever you swap/rotate tires or change pressures by a significant amount.
Additionally, do you have the optional in-tire TPMS sensors (discrete 4-tire readout) or the stock ABS-computed system? The former is more sensitive to change.
- Switch on the ignition
- Select in the Infotainment System: the Menu button > Vehicle > left control button > Service & Checks > Tire Pressure Monitor

With th this said, this information is reassuring this is common when switching out new tires and wheels. Is there a way to switch off the monitoring system, should I if so?

1. Only measure, set pressure and reset MMI when tires are dead cold.
2. Use a quality tire pressure gage. I use a longacre semi-pro model accurate to .1 of a lb.
3. Double check all measurements.
4. Recheck pressures monthly OR when average ambient air temperatures change more than 20 degrees.
Using these steps, the only time the light comes on is when the tire has lost pressure. This has happened twice on the current set of tires (~18k miles) and both times one the tires (which is specified by the MMI) picked up a nail.

I have after market wheels and have problems in the past which have been resolved by:
1. Only measure, set pressure and reset MMI when tires are dead cold.
2. Use a quality tire pressure gage. I use a longacre semi-pro model accurate to .1 of a lb.
3. Double check all measurements.

Why pray tell would you switch it off, if you could? It's saved my bacon a couple times. There may be a VCDS code but otherwise I'm not aware of a way to disable.
I've known folks with other brand track cars who've switched out in-tire TPMS wheels for non-TPMS and therefore had a constant dash alert. But they just put a piece of electrical tape over same.

I thought the tire pressure monitor was going off due to changing to aftermarket wheels. Well no, Audi states it’s due to a slow leak in the tire caused by the establishment who changed out the wheels. They may have cost me a $300.00 tire. Every time I go aftermarket something goes wrong, grrrrr.

Detecting a slow leak has been the primary benefit of TPMS for me.

I have been holding back to switch tires from the P-Zeros to the Michelin PS 4S, but now it may be time. Yes, the shop who changed the wheels will need to take ownership for the one tire, but might as well give them another chance to make it right. They stated they can get the new tires in tomorrow and have them ready on the car in the same day.
Whats your our experience with the P-zeros versus the Michelin PS 4S?
P.S. The slow leak resulted my tire pressure upon evaluation at 12psi.

As anticipated I really like my Michelin PS AS tires. A softer ride yet still excellent performance (and of course all season).
I'm sure the Summer 4S would be even better. Just do it.
