My 2008 E91 needs part 3450678412 (DSC control unit) replaced according to indy mechanic. I trust their diagnosis that it is actually the unit, not cheaper alternatives like wheel sensors, based on the fault codes 5DF0 and 5DF1 being thrown.

Indy suggested I try to find a used module from a low mielage car to reduce costs, as new units have an MSRP close to $1400. I've watched ebay for 8 months with no luck, perhaps because the market is tight for parts due to supply chain issues.

Does anyone have other suggestions for procuring a decent used module?

thanks!

The part number doesn't appear valid. I have several dsc pump/controller assemblies, and can probably help you out, but need correct info first.

Argh... typo: 34506784812. Also, the last 7 of my VIN are FV95137 in case that helps narrow down valid replacements.

Try looking for part outs on facebook marketplace.

Closing the loop on this, much belatedly: I've started using a bmw mech who does work on the side. His solution was to remove the unit and send it our for reman. A year later, all is good with this module/repair, and it was a fraction of the price.
