It’s the brake pressure sensors on the master cylinder. Just done mine and the lights went away and stayed away. You get a pair off eBay for under £20.

Hi, did you ever get this fixed and if so what was it. I have same 3 lights Brake warning, Tyre Press and DSC.
I also have a Steering angle sensor error 5E40 which wont clear.
Would appreciate how you got on?
I've been playing with this fault for a while now. Those specific lights along with the SAS error pretty much confirms it. I have a thread here with a $0 hotfix if you are so inclined to give it a try:
I should note that mine lasted 6 months and errored again as the brushes continued to wear down. I've since opened it up and cleaned it + relubed with conductive grease and it's once again ace. I daresay had I cleaned and lubed it from the beginning, it'd last another few years.
I'll be experimenting wtih replacing those brushes in-situ without removing the SAS from the car later (if parts ever arrive... covid19 please!).
I recently posted this which differentiates between a Steering related fault and an ABS fault both of which affect the DSC.

I have had both combinations and 1 was the ABS pump , the other the Steering angle sensor - which appears to be the combination you have.
You might want to invest in an ICar soft fault code reader which reads the faults and resets some although it only reset my fault once.
You can also press and Hold the DSC button to see if it will reset Likewise the TPS button to reset.
