I just swapped to coilovers and changed front/rear bumper and now I have this warning on the iDrive saying TPMS Malfunction. I double checked both of the front sensor boxes in the fender well and they are both plugged in.

Anyway to tell what exactly is causing the issue?

Did you already try a TPMS reset and that did not fix the issue? If the reset does not fix the issue, you'll need to scan for codes.

I did the reset on the iDrive and it did nothing. ALso no codes are showing for it.

You checked for faults in the RDC module, using INPA, or Tool32? It should give you a code indicating what caused the fault. Something like 604F for front left trigger.

The sensors are mounted on the inside of the wheel well liners, so if you removed the bumpers, it's likely that one of the connections to a sensor came loose. Did you check the rear connections?

Actually I forgot to use INPA. Forgot it was a thing.. I used MHD.

I will have to find INPA download again and put it on laptop.

Did you check the wires? Maybe a wire broke while removing or connecting the connector.
