TPMS - CAN protocol for BMW '13 328 (F30)

Post by jaytee »

I'm working through setup of an E36 M3 for track usage. I miss the continual tire pressure display on my Porsche to monitor the state of my tires.

Aftermarket systems (Stack, etc.) are too rich for my blood so I picked up a control unit from an F30 BMW for cheap.

Does anyone have experience with these? It's a Huf unit, so hoping it's not too proprietary.


Figure I'd ask before I go down the reverse-engineering route....

You might be the first one to reverse engineer. Is this a pretty stand alone device? Got pictures or links to more information?

Would be great to have this option available.

Here's a picture of the module itself. It has ground, power, CANH, and CANL connections and typically mounts under the car somewhere below the spare tire well. I think it's commonly used on BMWs and other makes, though each manufacturer may have their own CAN implementation.

From some digging, looks like it requires a "wake up" command via the CAN bus. Will update when I get it powered on and start tracing the messages. Might need to find someone with a F30 BMW willing to let me tap into the CAN bus....

Interesting. I noticed the same thing with a Fiat unit I tested; it never broadcasted any CAN data.

Looking forward to seeing what you might find out!
