So I only noticed this today, the yellow DSC light and the yellow brake fluid warning lights came on together (along with a short warning beep) and stayed on.

I drove to the local tesco carpark where I could pull in and check the brake fluid level, the level was fine, almost at maximum.

I turned off the the ignition, took the key out and waited about 30secs then started the car and the lights were off.

I then had to drive to Dublin from wexford, about halfway the lights came on again.

pressing the DSC button on did nothing.

Later today i was in the car for a while , waiting on someone (about 30 mins) I did the ignition thing again and the lights went out but after about 20 mins they came back on again.

I really hope this is just a faulty sensor or something ?

I read one thread where an american guy said he had the exact same problem and his garage wanted to charge him around $1,500 for a new DSC unit, but it turn out to be something else ( I can't for the life of me find that thread now as I was looking at it on the phone earlier)
