Surprisingly you can get a used one from the junkyard that's just plug and play no programming necessary. Just make sure the options are the same

hugus311 · 10-31-2015, 09:03 PM

what about upgrading to a mulf2 as mulf ones are prone to overheating like mine did?

You probably have a TCU not a mulf.

Also Dension gateway 500s bluetooth.
bluetooth phone usb ipod and streaming bluetooth
music.

hugus311 · 10-31-2015, 10:03 PM

what about Mobridge mp2 pro . anyone have any issues

ctuna · 10-31-2015, 11:55 PM

You may find it hard to locate someone with one.
They are most known for there Fiberoptic to analog
pre amp for the L7 system . It looks like there device
runs about the same price as the Dension.

At about 600 for either of these they are running almost
at the price of a new head unit with nav such as the
Dynavin N6. I think that one is about 800 with a L7
adapter.
I think I have seen the Dension on sale for around 450 at
some sites.

thanks ctuna. The n6 looks promising. Probably go that route. I pmed Jeff in regards to a qoute and some lingering questions that weren't answered in the 25 page thread I just finished reading.

ctuna do you have a dynavin unit? if you do what are you impressions on call quality of you do have one.

VTECaddict · 11-01-2015, 02:46 PM

Do you have iDrive?

For 2006 the BT is handled by the TCU and there is no MULF. Are you getting an SOS call malfunction too? If you just want to restore sound for now, you can remove the TCU from the MOST bus. You can use a MOST termination loop for $15-20 or just reconfigure the cables at the MOST distribution block so the TCU is not in the loop anymore.

To restore BT functionality you need to get a used TCU/MULF and get it coded to your car or try an aftermarket solution. You can also upgrade to MULF2 and retrofit 6FL Enhanced USB/iPod support while you're at it.

hugus311 · 11-01-2015, 02:51 PM

no idrive, professional system with L7 and bt. no sos error and your right it's a Bluetooth Telematics Control Module tcu

ctuna · 11-01-2015, 04:59 PM

There is a big Dynavin N6 thread on the audio board.
I don't have one but there are plenty of reviews.

I just have the pro radio with a cd player but I do have
and afermarket amp and speakers but I started out with
the Hi Fi system not the L7.

Dynavin thread.

Also are you sure its your TCU that's gone bad and not your amp . Because the TCU usually gives some other warnings or the telephone picture will disappear from the menu selections or won't be selectable. Have you checked your amp area for water?

yup. phone and bmw assist just have two lines and no longer selectable. tcu is done

I think if you bypass it on the most loop
your sound should come back for the stereo and gongs.
Either get a Most Loop jumper or I figure a cut down straw
of the right size to point the two fiberoptic connections at one
another might work. You might have to depin the connector
at the TCU to do this or you could bypass it at the Most Junction
Holder under the US Driver side passenger seat Side Bolster.
