DSC problem ;(

I have a friend who fixes cars that were in salvage state so I decided to get a car from him, he did everything great but there was a problem neither he or I could fix, the DSC won't work and therefore the brake,abs,the little circle next to the abs sign and in the middle the triangle with the circle around it all light up when I turn the car on. Now, the car is fine, everything else works perfectly except this but I'd just like to see if anyone could help me out or give advice how to fix it.
Btw, it's a 2004 BMW 330xi

Drive the car for 5 miles and see if it goes off. I get those lights often when i've had the battery disconnected.

Otherwise scan the codes- probably a wheel speed sensor issue if i had to guess.

wheel speed sensor

It's been like this always though, ever since the car came in and it never turned off. Nor does the DSC button do anything.
Are you sure its the wheel speed sensor?

You can get the DSC codes read to be sure. It will cost $125 to get codes read, but the DSC module reads which wheel sensor is faulty. In my case, my rear passenger sensor was scrapped by a rock caught in the hub.

is it hard to change the sensor? and how could I get the codes read

Phone around for best price - reader needs to read the DSC codes. The sensor is held by one hex bolt and connected electrically by an end harness that tucked in a box under the car.

okay thank you I'll see what I can do

good info!!
