    Seems that BMW have come up with a fix for their failing DSC Hydro Units on the E90, E91, E92:

    B34.51.6.797.896 646 HYDRO UNIT REPAIR KIT £144+VAT

    Certainly a lot cheaper than the £1700+ horror stories I have heard about

    Well done BMW

    Well if that is correct then as you say well done BMW

    Not before time, although this problem effects a great many cars (not just BMW) fitted with this type of system...

    gaznav,

    my 320d is going in for diagnosis of what I believe is this very problem on Friday.

    Can you please provide me with any further details of the repair kit?

    Cheers

    That is the repair kit part number. The hardest part of the job is removing the hydro unit itself and bleeding the brakes.. The rest is simple

    If its the unit itself faulty ity usually comes up with a pressure sensor fault code...

    Hi All,

    Same issue fault code 5e20 and warning lights - but on earlier E46 - anyone know if there is a repair kit for these or if they had a separate sensor so cost of repair is not too bad?

    Car is now 8 years old with 75k miles- bought from dealer less than a year ago and he ignored my requests to assist with this getting fixed.

    EDIT: Recognise this should be in E46 section...

    Pressure sensor is built in and there is a repair kit available, but it is more expensive.

    Hi there

    I just had my Z4 warning lights diagnosed by an independent BMW garage and it came back with 5E20 pressure sensor and 5E24 pressure sensor. It's a 2004 car with only 28k miles so what is my best course of action to avoid the 1824 pounds I was quoted for a new hydro unit DCS?

    If I take it to a dealer will they be able to get a repair kit instead as mentioned above for some other BMWs at a cost of around 400 pounds?

    Please help! This is a scary bill I really want to avoid if at all possible!!

    Thanks

    From what I have read the repair kits are availiable but they are around £900 +vat for the Z4 and E46...
    Not a long job to fit them but the part is a stupid price. The problem with the Teves units are that the pressure sensors are built into the modulator and the modulator hydro units cannot be opened or repaired...

    The only way around it is to try and find a second hand unit from a breakers, but that will still need coding to your car. But it is a gamble if the second hand unit will do the same thing as yours...
