Does this allow you to keep assist? I wonder if the newer module will work with the X5. There was a specific issue with the X5 wiring. I know a few people on the forum tried the TCU in the early days with no luck what so ever.

Thanks for the update though. It may be worth looking into.

Yes, the newer TCU has Assist - but I'm not fully aware of all the Assist coding, and don't want to mess with Assist too much, as it's too hard to test
eg: there's settings for Auto-Emergency call when airbag goes off, etc

Contrary to my previous comment, I got curious and started writing code.

Reading ID, determining telephone type (ULR or Everest), Reading emergency phone number, reading and coding VR on new TCU now work.

I'll add the SDV and then see if I can squeeze in the other phone numbers... and then I need testers to verify for me

Hey - any luck with this? I have posted in another thread that i retrofitted nav and got a harness from what i believe is an older X5 (03 or 04). I didn't go the retrofit harness route.

So when i plug in the module (not knowing i didnt have ulf or what tcu was ) everything goes blank. Is this likely if there are issues with older models using the TCU? Essentially if this is an older harness it goes back to older model in terms of wiring correct?

So OP - how did you get TCU working with an "older model"?

This TCU has been installed in several E38, E39, and E46 cars from 2000 to 2006. The wiring became standardized across all models in 2002. So, any US-spec harness 2002 or newer would work fine.

I read through your other thread, and I think that I would buy that you have a harness for the BIT-II system, but that is a possibility. Something is severely wrong if the telephone module effectively crashes the entire audio/nav system. If I were you, I would look up the assist wiring harness on the BMW wiring diagram software, and carefully compare it to the 54-pin plug in your harness. Then, I would go one step further and us a multimeter to test the wires to confirm that they are what they should be. Like ccfj suggested, you probably have a fault on the I-Bus wire. That is where I would look first.

ok thanks. The wiring actually came from europe car since i bought it from ebay. I'm very close to just paying for my mistakes and buying a new harness.

you mean to say that you doubt its a bit II system harness? I have the wiring diagram software - not sure how to run it though LOL. Will take a look.

Yup, that was a typo in my note. I meant say that I did not think you had BIT-II wiring... However, that was before I knew that you got it from Europe. So, given that you have no idea the source of the wiring, all bets are off. Plus, the harness is a mismatch for your DSP. You are 0 for 2. It is a tough decision, but I would consider starting over with a proper harness. You can probably get your harness working, but it will take some effort and a lot of very careful wire tracing against the wiring diagram for your car.

Yup I hear you. All bets are off for sure. I had the harness installed by an indie mechanic so i dont know if i want to get the new one and incur the cost for another install. DSP i'm not concerned about - I want to put in replacement amp and sub anyway.

I opened up the wiring diagram DVD I have and i'm not an electrician. Can't understand it.
