Traction control, abs and tpm lights came on yesterday??
So yesterday, all 3 of these lights lit up, I thought they would be gone this morning, but are all still there.....anybody have a clue? My only thought...is maybe the battery??
Others would know more about how to diagnose this ZippyNH or GreekDrifter have a bit of knowledge here but YES -- every wheel has one.

Bad when speed sensor...
Each hub has one screwed in....
Different part front and back....
A pro style unit odb2 reader can read which one is dead in some cases...consumer units, nope. Some computer/odb2 cables with programs can do it too, like bavtec, etc...not sure of others.
You have to what is called a "tri-fecta" on these boards....all 3 lights....all 3 systems need the input of the he sensors to work....
The trifecta is a right of passage for MINI people. Like crossing the equator, mile high club, short snorters, old guy's zipper club and etc. Welcome to the fold.
Here is the sensor and options ; diagrams for removal and what to watch for.
A MINI dealership can scan and see which one is bad to what corner, if one of the sensor is bad after all the sensor heads are clean, short section right near the wheel bearings. Otherwise, you are just cleaning the all sensor heads behind the wheel bearings first. Then inspect every two pol connection , the sensor have a deep blue socket connect and it has to be clicked all the way up. Also inspect on the male side to make sure the terminal are not corroded past the plug on the top where they go into the plug harness.
The old ones are most of the time rusted into the steering knuckle/ carrier. So you will break everyone of them trying to remove them.
When installing the ABS sensor make sure you clean out the insertion hole, as I have had corrosion built up and when you slide it in they tend to stick. When you pop the old one out and its damaged you might have to take the wheel bearing off to get it from the bottom and push up. Soak the top of the sensor insertion with some PB blaster or penetrating fluid and let soak. There is a little hex head screw that holds in the sensor. #3
For the rear follow the same thing: These go straight in from the back side of the trailing arm.
and god love you too ecs...thanks for the input.
I bought my timing chain tensioner from you (amungst other parts)..1 week before this happened to me..or else i would have made one purchase.
Mine came on yesterday... I suspect it is the wheel speed sensor as I just replaced the front R wheel hub and the rear L hub... the code that the Bavarian tech software is showing is 5E24... which is actually a DSC code that reads Pressure sensors not plausible; pressure sensor 1 / 2 not plausible.... but I found the code on a BMW site that refers to front wheel speed sensor. Unfortunately it does not tell me which one- since I did the front R I am assuming it is the guilty one since the hub was very stubborn getting out.
I would inspect them both physically for damage and if you cannot get a full read out from the dealer, Try one on one side, then the same one on the other. Otherwise its a guessing game. That does take some time to install. But you would be able to know, unless both are bad, which does not happen to often.
What would trigger just 2? I have tpms and traction control consistently on... i hit several pot holes at once when they came on.. any trouble shooting would help.
Now thats weird, Get a schwben tool and scan it, Might be that the ABS led light it burned out and you do have it , ( not showing up ) or you have something else going on.
