So, the dealer 'said' the module in the car was bad (Some time ago)
The system shows "?" for all 4 tires (the sensors could be dead also).
I got a used receiver module that was 'supposed' to be good.
I went to swap the modules and noticed that several wires were crimped in the harness. (It looks like a VW dealer put some new pins in the connector.
I don't know if this was done when they said it was bad, or if it was done before.
So I swapped the modules to see what happens.

Old (Original) module:
Start car and get a low tire warning.
"Bad Wheel on Car" message displayed.
All tire pressures show "?"
If I drive the car 4 miles I will get the "Flat Tire" warning, and at that point you can no longer get to any of the menus to see what it thinks the tire pressures are.

New (Used) Module
Start car and get "Flat Tire" warning almost right away.
At that point you can not get to the menu to see what it thinks the tire pressures are.
Have not driven the car due to other work being done.

No module:
Start car and get "TPMS Inop" warning right away
The Tire pressure is not even in the menu.
As above I have not driven the car to see how annoying this would be. (Does it keep beeping, etc.)

So any guess is to whether one or the other module is good or bad?

Need a vcds scan of the car. One scan with the old module installed and one scan with the new module. Need to inspect the wiring mods that are done to the harness. Inspect the old module to see if there are any signs of damage to the connector.

I had a similar issue years ago with my 2004. Seems the batteries don't die out all at the same time and I wasn't thrilled whenever the system said I had a low tire. But it was usually 3 psi low if even. So I had the dealer essentially turn off the TPMS and now I check air pressure the old fashioned way. With a good tire gauge. One less electronic/digital item to be concerned about.

I am thinking the best way to go for now is to disable the system.
Is there any way to do it without VCDS?
Is there a way to force the car to relearn what modules exist manually?
Can ODBEleven do it?

I asked the dealership one time when my truck was in for service and they shut the system off at no charge.

I may try that.
I have to take it in for the gas tank recall, and was planning on letting them do an oil change.
I leave the module disconnected and ask them.
