The iCarsoft shows lot of faults.
Is the dealer recoding my only option? Car is a 2007 335i convertible, 49,000 miles, original owner. Trifecta for 2 years.
Dealer has tried to scam me twice. Once when fuel pump threw a code, (3500.00 estimate) and refused to replace a flat tire with a stealer provided 1000.00 tire warranty. Car was 8 months old with 3,000 miles. Said nail is not covered.
Never been back. Even the "free oil changes" were not worth arguing that brake fluid does not need changing more frequently than engine oil.
If clearing the code for the fuel pump is 3500.00, recoding ABS might be 10,000.00. After I refused to authorize a 3500.00 "repair" they reduced to 1500.00. I cleared with the iCarsoft and drove off.
I know this dealers service department is an anomaly.
Really do not want to go back.

Did you send your original pump/module to Module Masters, or buy one second hand and send that in?

If the former, I'd look at the coding forums and ask some questions. If the latter, pull your old module off and put it on. Make sure you follow the bleed process. Clear your codes and drive for a bit. That's what I did and it worked. Also have a 2007 e93 335i.

I ripped out my bust DSC pump today (not a terribly tough job - more time consuming) I'm looking for a used one, however i'm just a little confused by what part number to search for. It seems the e90 series (i have e93 355i 2008) has the same pump but lots of different part numbers. the part number on mine is 3451-6784765-01 but i'm also seeing the same cars with 34-50-6-777-164, 3452 6784766-01.

Is there an updated pump part number (later pump) i should be looking for or anyone got one they're willing to sell - ship to Sydney, Australia?


cheers!

emdosmike I had the same 3451-6784765-01 POS abs pump in my e92. I did a lot of research in getting the latest pump i could find for this model and apparently the issue was fixed with the 3451-6790146-01 pump and i've had no issues since.

Video shows swap from 3451-6784765-01 to 3451-6790146-01

So annoyingly, i removed my pump, ran 12v battery power through the motor and it spins just fine. Could this mean my electronic module has failed?

Also i'm still a little confused. On realOEM.com it says the latest and greatest DSC for this car is p/n34502460431 with no mention of P/N 3451-6790146-01

Codes? its probably the latest and not factory fitted so its unlikely you will find used one. Only about US$2500 for a 34502460431

GovernUrMental OK i've found someone selling p/n3451-6790146-01 (out of a BMW 1 series)

The supplier is stating...

'Based on BMW database this will not fit as the OEM in your vehicle is different from this one. We sell parts based on vehicle specs. You may purchase this item if you will insist but we cannot guarantee this will work on your vehicle and the item cannot be returned if it does not fit.'

i'm with you on the fact that it'll probably do the job, but just checking that the car model shouldn't matter...?

What were the codes though before your removed it? 5DF0 5DF1?

They all say that lol. from autopartscentre? $495? forget that. either buy from the US or bmsparesmelbourne usually have some for way cheaper

Hi Guys

I have the trifecta lights. I pulled the code using INPA: 51AD.
It does not show the common 5DF0 5DF1? Could it be the ABS module?

Changed motor bushes way back to fix my 335i. Search well known website for "abs pump motor brushes bmw" or similar. Took me an afternoon to rebuild the motor, you need to be reasonably experienced in this stuff and quite brave. The motor wasn't designed to come apart with normal tools so you have to be a little destructive and there is a risk you will destroy the unit beyond repair. I bounced the armature on the floor when it came ut of the vice but fortunately it survived. Spun motor up before and after, didn't seem to be a huge difference but fault went away and never came back.

Bled the brakes, stamped on the pedal 2 - 3 times at walking pace and no further problems.

Nice write up!

I'm researching this now, realoem and ista all have different part number.

From what I can tell there are only two variants for the non xdrive models.

The cheaper is the one for the 4cyl that has two torx screws holding the pump to the module.

The other from the 6cyl models has a pump that is pressure mounted with two notches on it in the aluminium housing. The module for this one is held in place by 4 torx screws that are visible from the back of the module.

Later models of the 1 series appear to use the 6cyl DSC for all models, and they have 116d for example that you can find for very cheap.

Can someone help confirm this assessment?? (I'm working on this assumption and swapping in a DSC from a newer 116d that seems to use the same description of pump.
