Subscribed - unfortunately. Got the double lights today, and the fluid is not low. In fact it was a little too high, so I'm going to drain a bit and see what happens. Have a DIY event this Sat, hopefully the shop can read codes.

I had these lights come on about a month ago. Shut the car off and started it and they went away and have come on since then. Been wondering what the hell happened.

Disabling DSC and having multiple related lights illuminated due to an issue within the system are two very different things. Had the double lights, unfortunately at the end of the front straight at VIR, and found myself with almost no brake pressure and a nice jaunt through a field. Id say that OPs decision not to track was probably a safe one.

This happened to me as well. I replaced both DSC pressure sensors (Master Brake Cylinder). I bought the cheap sensors off ebay for under $20 each and they did the job.

Ebay sensors still working? Worried about going that route but these sensors are expensive. Will check with reader when lights come back on.

To each is own, but from my experience its not a job you want to do twice. Paying a shop or pulling them out yourself. Buy OE sensors from fairfax BMW, replace them and they'll be good for another 10 years.

ABS is disabled too.

Anyone try this, disconnect the relay a few times? Seems like it can't hurt:
