DSC hydraulic unit failure 2008 335i 15500k

My 2008 335i has just 15500 miles because I don't drive it in the winter. Last week the ABS light came on. The dealer reports that the DSC hydraulic unit has to be replaced at a cost of $1935 (1348 parts, the rest labor). Anyone with a similar experience? Any help from BMW?Thanks.

What failed the dsc hydro pump? Or the control unit?

The dealership wants to repalce both but more often then not, only one component has failed and the failed portion can be swapped on from a donor used unit.

If the pump has failed, you don't need any coding as you will be keeping you control unit. If the control unit has failed, you will need to code it in.

I would check if there is power at the harness. I've seen instances where the power line for the pump gets shorted and throws faults for a bad pump. This is more common on the early R53 mini Coopers though, but the dsc hydro unit is the same across BMWs minis and even BMW motorcycles

Yes this happened to me. Before I did adequate research I bought a new assembly from BMW of Minn for around 960 bucks and that was all three assemblies as in aluminum ABS module, Bosch electric motor and the electric control unit. Just like what you see when you pull the entire assembly.
Well after replacing the unit and clearing the codes I researched this. I discovered that the primary failure is brush dust cogging the two brushes in the Bosch motor. That throws the code and that is what cost you the bucks. A couple of youtube videos showed how to remove the motor and gain access to the brushes, clean them and put it back together. I did this for my 3/2007 and verified it worked correctly now I have a spare unit. There is a company that does redo the motors and fix this issue called Module Masters but they are reluctant to do this on some 3 series BMWs. There is a British company that does this for around 400 bucks. My work cost me nothing. I cut the motor can open where needed to removed the can from the Bosch motor and cleaned the brushes, made sure they operated correctly and reassembled it. Having never seen anything but the youtube video I cracked the can open in about 20 minutes and had the unit reassembled in an hour. I am somewhat handy but this can be done by anyone. A small electric motor shop could do this for you in no time.

Fdrikker9 is correct that you can swap modules which is what I did and only needed to clear the codes not recode the unit which for me would have been a trip to the dealer since my coding software isn't that good.



What a shame if that is your problem that we all get abused for a poor quality Bosch electric motor with brush material (graphite) that gums the brushes themselves. I think the British company changes the brush material to carbon but not certain.

All I know...
