I know it's an old thread. But can someone tell me if this is he issue that it happened to you!? I double check my wheel sensors and they are impecable. They look news.




Thanks

I'm new and could use a little help. 2007 BMW 335i with 37,600 miles on it....I'm the original owner and getting ready to sell it. ABS light came on at about the same time as service light & message for Brake fluid flush. Took it into the dealer and their write up, along with a $4,300 estimate is as follows:

"DSC Unit failed. Connected vehicle to battery charger and performed vehicle test. Found fault for DSC control unit and connector. Performed Test Plan. Checked wiring and fuses to DSC Control Unit. Wiring and fuses found OK. Concluded DSC control unit to have failed."

Is this reasonable? Could it be something else? Any guidance you can provide would be appreciated.

Wow.....
The DSC module is available as a complete assembly and BMW also sells the control unit only. If the valve block is faulty then you will need the complete unit.

Sometimes you'll find the control units separated on eBay. Be sure to get one off a 6cyl as the 4cyls use a different module

BMW have stopped selling cheap cores for these units.
I just had a DSC unit failure on my 2005 1-series. The replacement hydraulic unit was $2500.
Instead I bought an used unit from a 2012 3-series with low milage for $250, coded it with the correct VIN number and initialized the pressure sensor.
Works perfect.
In realoem it didn't seem like the 2012 unit would fit in a 2005 model, but it worked fine.

I used NCS expert to code the VIN and Rheingold to initialize the sensor.
