I have a 2015 F56. I did my first (like, first one on this car--previously done by dealership) oil change (just fell out of maintenance) on Saturday. Went great. Very easy oil change. First thing Sunday, I fired it up and got a TPMS malfunction error. Tried to reset. It started to reset, then errored out again. I checked pressure by hand, and it was spot on.

I fired up my OBDII scanner and the car reads clean--no error codes. I'm hoping this means that I just have a bad send module in one of the wheels? I'm wondering if anyone can suggest something else, or confirm my hypothesis. My tires/wheels are ~3 months old. Got a set of winter tires/wheels from TireRack w/TPMS installed. Initially, there was no problem with TPMS errors, and it's been fine since I put them on the car.

I read that battery voltage can cause this too, so checked my battery. It reads 11.6V. It's original, so probably about time to be replaced, but it didn't strike me as THAT low. I'm hoping the oil change thing is just a coincidence. It literally couldn't have been any easier. I didn't have to go digging in the engine compartment, so it's really unlikely that I jostled any components related to TPMS.

Also, please don't turn this into a run-flat/non-run-flat discussion. Run-flats saved my butt at ~11:30pm outside Flagstaff on the last MTTS. I'll put up with all the complaints and grumbles people have about them if it means my son and I aren't stuck waiting for roadside 2000 miles from home.

Cheers!

Maybe one of the internal batteries on the TPMS sensor went?

That's what I'm thinking. Kind of wondering if anyone can verify that that's the error I'd see. Initially I thought if it was just the sender, it would just report that wheel as flat, but the more I think about it, it makes sense that 'no signal' would trigger a malfunction rather than a 'low' warning.

See if its warrantied otherwise you would need a new one.

I believe any good tire place (and many parts stores) can test your TPMS sensors for a dead battery. BUT be aware that in general TPMS sensors don't have replaceable batteries so you may be looking at buying a replacement.
