The other day when I went to leave my Break, ABS and DTC lights all turned on. They when off later in the day. It has done this for 3 days in a row. The error codes that came up are 5DF0, 5DF1 adn D35A. Is there a common issure that causes this? I have a 07 338I. I checked the live data on all the wheel speed senors and they all appear to be reading correct when the error lights are on.

Thank you

What are you using to read those codes? I answer your question below, but you ought to check the documentation/manual for your scan tool (or identify it and ask for help using it), as codes WITHOUT Fault Code Definitions are NO HELP. The warning icons on your Instrument Cluster tell you more than the numbers alone -- you KNOW you have a problem with the DSC/ABS.

So what's a fella to do with codes & NO definitions? Fortunately there's "BMW Fault Code Lookup":
www.bmwfault.codes

Plugging those 3 codes into the "Enter Fault Code" search box yields the following (it would be helpful to know what the SGBD or short code is for you DSC module, but my SWAG is it's either DSC 85 or DSC 87):

5DF0 DSC: Hydraulic unit: pump motor dsc_87 Dynamic stability controlMK60
5DF1 DSC: Hydraulic unit: pump motor connector faulty dsc_87 Dynamic stability controlMK60
D35A No message (CAS 0x304), receiver DSC, transmitter CAS dsc_87 Dynamic stability controlMK60

Those code definitions by themselves suggest to me that you might solve your issue by disconnecting the Connector to the Pump Motor and clean the pins/sockets with Electronic Contact Cleaner, and inspect the wiring, as it appears you have a bad connection.

2007 models had circuit/fuse changes effective 3/1/2007 build date, so check your door jamb for MONTH/YEAR built. The information that follows relates to 3/1/2007 to 8/31/2007 built (late 2007 models). Early 2007 models will have different fuse numbering, and perhaps OTHER differences.

Here's the TIS circuit diagram for the Module (A65a), & Connector (X18303):

Here's the TIS Installation Location for the Module & Connector:

Please let us know what you find,

Thanks. I have tried disconnecting and reconnecting the connector at the pump but I haven't tried cleaning it. I will get you more info tomorow.

Just to make sure we are talking about the same connector, here is TIS "Connector View" of the 47-pin connector, and also the "Pinout" for that connector:

I used Carly for BMW and a Autel scanner and got the same codes on both.

I'm not sure what the SGBD or short code is for my DSC module. How do I find that?

My cars build date is 10/07. That is the connector that I disconnected. It is connected directly to the pump. The lights did not come back on today, yet.

Thanks

The light stayed off for about a week and came back up this morning.

Please provide ALL CURRENT fault codes & Freeze Frame Data from your DSC Memory, along with WHICH instrument cluster warning light(s) are on and the mileage at which they came on.

The SGBD is the code for the DSC and its programming, such as DSC_87 that is found in the "Information" screen using INPA. I don't know whether Carly or Autel is able to view that Information, but its in Module memory. It is helpful to have that, as the Definition of a particular code can vary in some instances depending upon SGBD.

BTW, a 10/2007 (October, 2007) build date would be a 2008 model AFAIK. Can you confirm the correct build date per the door sticker?

Thanks,
George

The pump motor on your ABS module is faulty.

You will need to have the hydraulic part of your abs pump replaced/refurbished.

[OG Style]

I will have to get you the codes when it happens again. It went off later in the day and I cleared the codes. The door sticker say 10/07.

What usually goes bad on the pumps?

Thank you

Many things can go wrong but your codes are saying its a problem with the 12Volt motor attached to the hydraulic block either the electrical connection to the motor or the brushes are failing but the motor is not a part you can replace yourself as its clamped into the hydraulic block.

The internal brake pressure sensors can also fail but you do not have that problem.

Next time it happens you could try a sharp tap to the motor with a small hammer, this may give a temporary fix but ultimately it is on its way out.

[OG Style]

I'll give that a try. I will also save the codes next time it comes on.

[OG Style]

The lights still haven't came on again.

[OG Style]

They came on again and this is the errors I am getting.

Get your DSC module refurbished or replaced. I had two of them go south on my two BMWs at the same time (I know right?) and used Module Masters for one of them and a used unit for the other. Both my cars are 2007 with similar mileage, low 80K's.

I have a 2008 e93 convertible with only 58k, and the motor on the ABS is shot. How interchangeable are the hydraulic blocs? Can I get a bloc with a motor from a 2011 to match up to my DSC electronic front part? Are the cylinders inside the bloc the same from year to year?


I've looked at real OEM and it's not much help. The blocks all look the same for the 328 series. Any advice would be helpful.

Thanks!

My light keeps coming on and off randomly. I looks like I will have to replace or try to rebuild it. Do you know if the motor separates from the electronics?

I sent the whole works off to Module Masters. There are videos of folks fixing them on their own, replacing the motor or brushes I think.

The sad thing is I have a 2007 BMW 328i (I am the original owner as I bought it brand new) and I only have 36K km not miles on the car and my bloody ABS pump motor is shot. It started out with all the symptoms you mentioned. Now the ABS light is on all the time. As you can tell I don't drive the car much (only in the summer on weekends) but eventually I will get it rebuilt at Module Masters .

It does piss me off that with so little kms on the car the ABS pump motor went. I believe it's a defect of them using carbon bushings that foul up the pump

[OG Style]

That stinks. I will have to try to rebuild it my self or replace it. I can't send it off because I don't have a spare car to use. Hopefully I can find some info on rebuilding it.

Hmm, interesting data point. BMW does stuff like use the ABS pump to 'prime' the brake pads against the rotors occasionally, which adds to the use of it. But that would not explain your situation. Something time related perhaps. Hmm.

From what I've been reading, the aluminum block (and attached pump) do separate from the control module (black rectangular piece.

I have 3 vehicles, a 2011 BMW e90 with 92,000 miles, a 2008 BMW e93 hard top convertible with 58,000 miles, and a 2005 Lexus RX330 with 104,000 miles. In the past 4 years, the Lexus has cost me $200 to repair a single issue. Everything works with zero defects; all the lights, ice cold AC, factory nav, power windows and locks, bluetooth, HID's, ABS, DSC, power hatch, and all the hundreds of little things. No issues year after year. Both the BMW's fail constantly. I would not take either on a 2 hour road trip. The 15 year old Lexus I would drive to Australia if I could (I live in Florida). I think I'm about done with the German ultimate driving machine. Need something I can rely on. The beemers look great, nothing more. Just my sad 2 cents!
