The original ABS control unit of a 2013 F06 650i xDrive Gran Coupé has a short circuit and now that I put in a different used ABS control unit, made by Bosch, I get these error codes inside ISTA+ software:

2290B: DSC control unit: Conduct coding and startup operations, wrong car

4809CE: DSC: code not suited for all wheel driving

The two ABS control units in question are these two:

The parts number of the original is: 3451 6853405-01 | DSC / DXC9 L6 ACC

The parts number of the substitute is: 3451 6853400-01 | DSC / DXC9 L6

Could theorteically somebody, with more skills than me, reprogram the substitute so that it fits the F06 fully or is it better to send the original with the short circuit to a repair center as the subsitute is plain wrong for the F06 and will never fully fit no matter who tries to reprogram it? Any clues and recommendations are appreciated!

Here are some pictures of the ABS control units in question (first the original and then the substitute):

wrong unit
you need without ACC option
and its not possible to reprogram you need to buy proper one
Thanks for your response! You mean I need a unit WITH ACC, right? The original features the ACC descriptor in its "name" while the replacement unit doesn't have ACC anywhere.

Either way, it seems to be clear that there's no way around buying a new control unit or at least sending the original one to a repair service.

Thanks for the recommendation @maron and @masa52 !

which one is your ori?? with acc or not? you need exact as your from factory
on ebay is plenty used units so shouldn’t be a problem to buy it
also after swapped for correct one you need to code to your car using esys
Ista wont do that

The original is the first picture, which features the letters ACC, and the last picture, the one with the red and yellow scribble, is the replacement. I guess my car features an ACC system originally, and the replacement just doesn't have it and thus can't even accept all wheel drive code for this specific car.

The replacement unit that has those red and yellow scribbles is part number 34516876912, the first number on your list, yet it doesn't have ACC and that's why I can't replace my original unit. If that number is on your list, however, and you were able to check it with my VIN, does that mean that there's still chance that somebody could reprogram it so that it works with xdrive and ACC? I don't believe I'll get around getting the original unit fixed...

Will this part fit? @maron @masa52

You've listed the part number 34516876912 , but this one is 34516876913. Only the very last number is different, but maybe that's enough to make it unfit for my BMW F06. It's originally taken from an F11 BMW.





This one is from a F10 with 10000 km less than the previous model above from the F11:


Will both fit my F06? Both have ACC ending, but I'm unsure about the parts numbers..

This part here that was mentioned earlier: BMW 5 Touring (F11) ABS-Pumpe 34516876912, 34516876912, 0265256334, 3451687691601 Willkommen bei Autoparts24

I talked to the staff there and they've checked my VIN and told me that it should work. The F11 donor car also used an ACC system, which means that that ABS pump should have it too. I can't see the label however but the guy reiterated that it should fit...

Fits in the first image
Second DSC
The VIN is the same as the vehicle I wrote the link to.
It is a DSC that supports ACC from VIN, but it is better to finally decide on the label (DXC9 L6 ACC).
I think I'll go with the last one, as it costs 3 times less and it's from a similar car as the other two ABS control units. BMW 5 Touring (F11) ABS - pump 34516876912, 34516876912, 0265256334, 3451687691601 Welcome to Autoparts24

If the donor car has ACC, how is it possible that the ABS control unit doesn't have ACC? Surely BMW won't install it then inside that car?

I wish I could see the label too but the guy at the parts retailer won't do me that favor...

You said that the first car in my previous post has a compatible ABS control unit (BMW 5 Touring (F11) ABS-Pumpe 34516876917, 34516876917 Willkommen bei Autoparts24), as it does feature ACC on the label. Here's that car (530d xDrive):


And this is the car of the much cheaper ABS pump that I bought (BMW 5 Touring (F11) ABS - pump 34516876912, 34516876912, 0265256334, 3451687691601 Welcome to Autoparts24) (535d xDrive):


I don't believe that those two cars have different ABS control units, both are made in December 2016 and both should have a similar control unit feature set, at least that's what I think. Am I wrong?

I just saw a different ABS pump:








It has the same part number as the unit that I bought 34516876916-01. I don't mean the number on the label, but the number that's etched into the metal part of the pump.

Here's a photo of the bought unit:



Even though I don't have a picture of the label, I think it's fair to assume that the bought unit has the same label with ACC, no?

They also have the same number at the top of the control unit (0 265 256 334). This is the unit that I bought (that number at the top of the first unit can also be seen in the first picture of this post):
