Hey guys, wondering if someone can help me out. I need to replace my MMI control head. Was told the part # was 4F0 910 468 A by my shop and 4E0 035 729 by another site. Can anyone clear it up for me or point me in the right direction?
Thanks.

Neither number shows up in ETKA 7 or in www.genuineaudiparts.com data base. I would check with your local dealer to verify.

If your MMI is not completely dead and you can do a VAG-COM scan or if you have an old scan recorded it will tell you the part number. Here is a scan of my 2008

Address 07: Control Head Labels: 4F0-910-7xx-07-H.lbl
Part No SW: 4F0 910 732 D HW: 4E0 035 729 A

Note the HW part number is the second number you listed.

There is a 4L0 907 468 B (you have 4F0 prefix with an A suffix) shown below. That is the CAN bus gateway.

Found this used one on eBay:

Looks like the SW been updated on this unit 4F0 910 731 B
the higher the # means Audi fixed the buds of the earlier ones.
