Congrats, you have read up, done your research, and are spot on! The 2001 MK60 control module has an even higher failure rate than the 2002. They usually are not rebuildable.

Buy a good used MK60 from a 2004+ RHD 325i/325Ci/330i/330Ci, replace yours, then code it to your car. Your 2002 has “FA” style module coding, not the pre 09/2001 “ZCS” style coding.

Hopefully there is enough room to be able to just remove the control module itself and not have to crack open brake lines or remove the ABS pump. Matching exact part number is not critical; there were many revisions through the production run and so several different part numbers.

Fantastic thanks for that mate! I'll have a good look through that guide of yours and take you up on your offer if i can't figure out the coding myself first.

So just to confirm, would a DSC unit be compatible in my 2002 ASC equipped car?
There's some DSC units on eBay in the UK that are as cheap as $70 including shipping, the cheapest available on eBay here is $240+

Do you happen to know if this one from a 2004 sedan would work? ABS/DSC ABS PUMP & ECU MODULE 6750364 6753842 - BMW E46 3 SERIES #26 | eBay

This job started out at around $1600+ before I started to see if I could do it myself!

Here's a pic of my current unit I managed to take by squeezing my phone into a tight gap.

If you have the MK60 if should be DSC. Simple ASC is quite old, but different markets vary from USA. I cannot for sure tell you, so do some research.

 

I'm not confident about the differences between MK20 and MK60 units but I think I have an MK60 ASC unit according to this chart from another post here as my ASC Control Module model number is 6759075. How to Diagnose 'Trifecta Lights'

I also took some photos from INPA, only the DSC MK60 option in the menu works, the other ASC/DSC and DSC 5.7 options throw up an error.

I'll keep digging but I'm pretty sure I've read everything available that's in English at least haha. If anyone knows if these DSC and ASC units are interchangeable I'd appreciate hearing from you.

 

Ok so instead of spending $300+ on a used replacement unit, $500-$900 to have it rebuilt or likely $2000+ for a mechanic to do it all I'm going to give replacing the IC chip myself a go.
I'm pretty good with a soldering iron and have rebuilt a few 1970's amplifiers before. (Though admittedly they're much bigger on the inside)

As the chips are $3 each + $8 shipping I think it's worth a shot. I just bought three from here so I have a couple as a backup if needed haha.

www.bimmerfest.com

Will update this post when I have some new progress to share.

 

No worries.
Yeah I tried a DSC unit and while it technically cleared the 5DF5 error it brought in a new error, I think it was something to do with the steering angle sensor or one of the DSC specific sensors that the ASC unit doesn’t have, as the ASC unit doesn’t have them myself and Balidawg weren’t able to clear that error code in the software.

I found a used 6759075 ASC unit come up locally on eBay so I bought that and installed it, software reset easily and it fixed all my problems, I’m not sure how long it will fix them for as it was a used 20 year old part but it’s been fine for the past year now.

My thinking is if you have this issue in an ASC car you really can only go with that one specific part, but in DSC cars it isn’t as picky about which replacement unit you put in. I’d like to see someone successfully replace just the IC chip and document more it thoroughly here, one guy on the Bimmerfest forums seemed to do it successfully though.

 

Wow you have done a lot of research. Very impressive, well done.

Good luck with the IC change. Maybe you should take some photos as you go and write up a DIY. It would be a great contribution to the forum and the E46 community as a whole

Let us know how it goes..

 

Thanks. Yeah I will if it works of course.
I won't be able to post any updates for a while as it's going to take at least a month for the IC to arrive in the mail from China.
It's always good to have more info out there for these hard to troubleshoot RHD issues though.

And? How did it go? I have the same problem and want to repair my as well. What was your solution?

 

So I have a very specific problem with my ABS that I'm trying to solve, if anyone has any ideas I'd very much appreciate your input.

My Australian RHD 2002 BMW E46 325ci came equipped with an MK60 ASC unit, the control module has the part number 6759075.

I've removed the 2002 MK60 ASC 6759075 control module and have replaced it with a 2004 MK60 DSC 6765454 control module. The 5DF5 error seems to have gone away, but instead I now have 5E1F, 5E21, 5E20, 5E1E, and 5D8C. My trifecta lights have now changed into just an orange handbrake light and a DSC/traction control light.

Balidawg and I have been attempting to clear these errors and calibrate the steering angle sensor, the problem is that my E46 did not come equipped with a steering angle sensor. When you try and calibrate this in Tool32 it throws up the error "No response from control module"

Here's my original post of me attempting to diagnose this: 2002 E46 "5DF5 Internal control unit error" -...

So far I've only seen a few forum posts with solutions for 6759075 units, I haven't seen anyone successfully replace their MK60 ASC unit with a newer MK60 DSC unit.
I'd rather avoid replacing my ASC unit with one with an identical part number as there is only one ASC MK60 unit which was made in 2002 and it's known for failing, they are also quite expensive as I'd need to ship one in from Europe. If possible I'd rather replace this with a more reliable DSC unit from a newer model.

Here's the solutions I've seen so far:

Well in the end unfortunately I ended up botching the solder work and lifting a pad of the board. My solution was to swap in a replacement ASC module with the same part number from eBay. I still think this IC chip replacement would have worked but it’d need someone competent in micro-soldering.

Hi RR43. Did you manage to find a solution to the issues? Many thanks in advance!

 

I ended up solving my issue by replacing my ABS control module with another identical part number ASC model. Would be keen to hear if anyone else is successful with any of these other attempts.

 

Hi @RR43 mate I have the same issue and have found that I will probably need to do the same as you (swap parts). I can't start a conversation with you, but I'd love to discuss a bit more about the general taking off and refitting of the unit if possible please.

 

Hi @RR43 mate I have the same issue and have found that I will probably need to do the same as you (swap parts), I can't start a conversation with you but I'd love to discuss a bit more about the general taking off and refitting of the unit if possible please

So at the time I was originally planning on writing up a tutorial for this until I realised I really didn't know what I was talking about and then destroyed my old ASC module by ripping off some solder pads! I'm really not an expert on the E46 ABS issues by any means but managed to fix mine with a lot of help from @Bali who walked me through all the software side. The main thing I can contribute is just the research that I did that suggests that the 9369.1D 14 pin IC is the cause of the issues and a potential solution I haven't tested. I botched that part and ended up solving my problem by just replacing the control module with another identical part number model from eBay.

It's a bit of a pain to do but is WAY easier to do in a RHD car than a LHD, I did mine a few times as I was attempting to refit a DSC control module (unsuccessfully) but from memory I was able to do it in less than 20 minutes in the end. I then cleared all the error warnings by swapping in the new control module and resetting the code in Tool32.

The new unit was manufactured in October 2002 so hopefully it's from a more reliable batch then the original May 2002 unit I had, I haven't had any issues since but it has only been a year or so.

Here's my photos from half the tutorial I intended to make right up to the point I ripped off my solder pads and gave up, to swap the modules basically you just remove the bolts holding in the ABS unit and some other brackets that are in the way of your hands, unbolt the control module and carefully try and bend it out without damaging anything, (I had a friends pull the ABS pump and hoses while I pulled out the control module) then you can sort of twist out the control module and twist in the new one without bending the pins, the great part of this in a RHD car as it's possible to do this without removing the break booster and without needing to drain the break fluid. I watched the 50s Kid tutorial in a LHD car and that looks like a massive job and is very different in these RHD models.

Here's a heap of photos I took a year ago while I did the swap if it helps you.

 

It all depends on where the ABS module is mounted. Your RHD UK car will be different to the USA cars. If you have access, you only need to replace the black box section of the ABS module. It's held in place by 4 torx screws. If you don't have access, then you need to remove the whole ABS module. Get a set of brake flare spanners, so you don't round the brake tube nuts.

 

Thanks for the quick reply wow - it's literally the same as OP. But just to confirm, if I CANremove the back black box, then that is all that needs to be replaced. Otherwise the entire ABS unit needs to come out (and then be bled), correct?

 

Yes

 

I've been reading a lot of ABS related forum posts here and am seeing quite a few people say that 2002 unit's are pretty janky.

Yeah, this has been my experience with 2001-2002 ASC and DSC units as well.

They also suggest that it's better to replace these with later year units from a 2003-2005 car and code them to work.

Here's the thing - I've never seen a DSC or ASC module fail on the older cars - 1998-2000, and I've had a few of them... on the other hand, all 2001 cars I've owned for more then 8-10 months developed some issue with the ABS module, especially on cars with ASC. Here are some examples:

• 02/1999 328i sedan, 248k km - my sisters car witch I maintain - has ASC. She's owned that car for 13 years now, never had an issue with the ABS pump. I did replace the brake booster a couple of years ago.
• 10/2000 323cic convertible, 268k km, thailand model (M52TUB24 engine) - has DSC. I've owned the car since 2012, had 163k km when I bought it. No issues with the brakes whatsoever.
• 11/1998 318i sedan, 338k km - has ASC - replaced brake booster last year. No problems with ABS so far.
• 06/1999 320ci coupe, 310k km (M52TUB20 engine) - has ASC. Pretty ratty car, bought it initially to turn into a track only race car - ended up being used as a backup car for whenever I was tinkering on or maintaining my daily driver. Traded it for my 525d in 2019. No ABS or other brake issues.
• 06/2002 316ti manual - 220k km, DSC, swapped with an M54B25 off a rusted-out UK 325cic. No ABS issues so far.
• 04/2001 325cic convertible, UK model, ASC. ABS failed 5 months after I started driving it regularly. It started with rear wheel speed sensors - passenger side first, then driver side. Shortly after replacing them, I got "CAN DME/DDE signal error" and "Pressure sensor 1/2" + "Pressure sensor 2/2 not plausible". 2 lights on the dash, traction control and yellow handbrake indicator. At first, I thought I messed something up when I did the conversion from RHD to LHD, but it turns out only replacing the ABS unit made the problem go away. Sadly, I had to part out the car when it turned out the rear subframe, rear underbody and chassies reinforcements were completely rotted out.
• 06?/2001 316ti automatic, 273k km, DSC - failed master cylinder, no rear brakes when I got the car. Rusted out rear right brake line, 2 lights on the dash, traction control and yellow handbrake indicator. Replaced the master cylinder and rusty brake line as well as both rear brake hoses. Problem went away for about 100km then came back. Cleaning the ABS module's connector seems to make the codes go away for a number of KM, then they come back. I've cleaned the connector 3 times so far. I suspect brake fluid from the bad master cylinder somehow leaked on to the ABS module. Codes are "Yaw rate sensor faulty", "CAN DDE/DME signal error", Pressure Sensor 1/2 not plausible" and "Brake fluid level low".
• 2004 (can't remember the month) 330cic, 258km, DSC - ABS module failed in the first year of ownership.
• 11/2001 320ci, 300k km, DSC - my wife's first car. ABS module and brake booster failed withing 6 months of one another. 2 lights in the dash, traction control and yellow handbrake. 5 errors - "Yaw rate sensor faulty", "CAN DDE/DME signal error", "Pressure Sensor 1/2 not plausible", "Brake fluid level low", "Pressure Sensor 2/2 not plausible". Replacing ABS module solved the problem. Car was sold in 2019.
• 09/2003 330xd wagon, 338k km, automatic, DSC. ABS module was bad when I bought it. The previous owner knew and supplied a good replacement module but couldn't be bothered to have it installed since he knew he was going to sell the car. And neither did I since it was incredibly rotted out and I was only really interested in the engine and transmission to use in other projects, so I parted it out. 3 lights on the dash, never bothered reading codes.

What I am trying to say is that from my ownership experience later cars seem more likely to develop issues with the ABS pump, particularly cars equipped with ASC. This is a very small sample size however, so I could be wrong.

 

Interesting, it seems to specifically be the 9369.1D 14 pin IC on the ASC units that's the issue, maybe opening it up and preemptively adding a small heat sink to that component before it burns out might be a fix. That or just replace the chip, but I'm not good enough at micro soldering to successfully do this.

 

 

Wow thanks so much for the reply!

I'm literally on the same journey as you right now

"So far I've only seen a few forum posts with solutions for 6759075 units, I haven't seen anyone successfully replace their MK60 ASC unit with a newer MK60 DSC unit.
I'd rather avoid replacing my ASC unit with one with an identical part number as there is only one ASC MK60 unit which was made in 2002 and it's known for failing, they are also quite expensive as I'd need to ship one in from Europe. If possible I'd rather replace this with a more reliable DSC unit from a newer model."

I'm looking at replacing with another mk60 but as you mentioned apparently that doesn't solve anything, however you also said about a refurb - is that the only way to go, or that you'd suggest?

Thanks again!

you mentioned that you got a refurb unit, so did you
