Are you entering the VIN with the check digit as shown in NCS for example? i.e. 18 digits? it was tricky i was playing around with it and it took a couple of attempts. the problem with the navi is you have to wait 15 mins before it re-boots after ignition off.

Yes I did. I'll try again

Didn't get no errors, but it still changed back after 15minutes shut off test. Guess I'll just have to mess with it

Hi Paper,

Still no luck with the VIN change? I know it was a pain, I cannot remember the exact procedure, I will have a look in Tool32 to see if it will jog my memory and get back to you. I recall finding some info on the 7-Forum, its all in german so requires translating. Here are the links to the bits I found before.

http://translate.google.co.uk/transl...26prmd%3Dimvns

and on page 6 look at the attachment, its showing in tool32 to run the job 'get_factory_mode' it should return saying its active, when active write the new VIN with fg_schreiben. if it isnt active there should be a job called 'set_factory_mode' or something along those lines. I'm 99% sure you write 0x3F to set the factory mode, I cant seems to find where I read that.

Anyway, im after a favour from someone! Im after the AMP/TYCO part number on the 54 way TCU connector. Thats the White outer shell with the locking lever, the two row insert and the single row insert. (should be three part numbers in total)

If anyone could do that for me it would be most appreciated!

Stuart

I'll send you a link to the Ebay seller
Who sold me my plugs for the TCU when I
Get home in a few minutes

yes installed & working great . Have you finished your install of the TCU ???

Yes, I have had mine in for a while now and the Bluetooth works great without installing the Bluetooth antenna in the centre console. I am using the existing antenna on the rear parcel shelf as my Bluetooth antenna. I will eventually get around to installing the Bluetooth antenna in the centre console.

Hey, Got in contact with the guy, he wants $50 for the connector!

Been hunting on the net, Audi use the same connector on their bluetooth interface, part can be ordered from the dealer, unfortunately no Audi dealers near me, but I found a pic of the connector, managed to zoom in and enhance the pic enough to make out the Tyco part number.

Its:
1-1355928-2 - For the outer shell with the locking latch
1355929-2 - Single row housing
1355930-2 - For the double row housing

Tyco offer free samples, which I've placed an order for, however the drawings state the part is restricted to Audi and Jaguar, The order may get rejected, but hopefully not and I can get the connector set free!

AceFX:

Hows the comfort access retrofit going? That has got to be the ultimate retrofit!

Paper, I just bought a TCU from a 2007 BMW 750Li with 59,000 miles. Thankfully it also has the wiring still attached for me to re-use. Already did the coding in preparation for the new TCU. Soon it will be time to sell by CPT-9000 BTUM and rip out the phone cradle and reclaim the space in my center console. Hope this goes well and I don't mess anything up.

Stuart, where are you with that possibly fried LMA?

Are you serious, if I recall correctly I paid
$20 for the 54pin & $10 for the fibre optic plug.

Still DEAD! Tried everything I can think of so far. I have tried WinKFP with not much luck, im not sure if I havent set it up correctly or what TBH. when i tried re-programming it it didnt work but it did reset the unit so it must be doing something.

Tool32 does not communicate either, looks like its properly knakered. There dosent appear to be any way to recover it via the OBD socket.

Will look for another unit on eBay in the week, thing is I dont want to buy one only to find I will bugger that one up too.

I seem to be the only person ever to have had this problem, so it looks like im on my own!

Do you have Progman?
Maybe that will work for you.

New TCU I ordered yesterday arrived today! Can't wait to try it out, I'm passing an Audi dealer tomorrow so phoned today to order the 54 way connector, £2.45! That's more like it! Managed to source the MOST connector adapter from Farnell Components, £0.45 each should have that tomorrow too.

The wires/fibres don't look long enough to reach, the new TCU connectors are the opposite way round. I have bought some fabric harness tape if I need to re-route anything. Hopefully should have this lot fitted tomorrow night.

Got the discs for SSS, will see if I can get it installed later tonight and try to recover the LMA!

Cheers!

That's good news. I couldn't find fabric tape
When I did mine. I had to use regular electric tape. Good price on the plugs, you should post the link were you got the most connector for that price for any others that might need it

Hi, of course, the MOST connector adapter (when you remove the two fibres in the small rectangular housing you need another housing with a locking tab that plugs into the TCU)

In the US they are called 'newark' and Farnell in the UK:

http://www.newark.com/te-connectivit...tt=1-1355426-1

MOQ is 10.

The picture is not correct but the part number is, the Tyco link for the connector:

http://www.te.com/catalog/pn/en/1-13...PN=1-1355426-1

The fabric tape I got from eBay, its manufactured by tesa.

These are the crimps used in almost all 2.54mm pitch connectors in BMW's they are a special design with double retention, also available from Newark or Farnell.

BMW only sell these with lengths of wire for a ridiculous price!, if you have a suitable AMP crimp tool you are in luck!

Good Post !!!

Hey guys,

Good news, picked up the 54 way connector from the Audi dealer today and fitted the new TCU, coded the MMI and I now have 'Phone' in my settings menu, and it displays what I guess were previously paired phones from the donor car.

I have tried to pair my iPhone, I select 'Pairing' on the menu and my iPhone finds 'BMW9900' or something like that however it wont pair with the pass key I enter from the label on the unit. I have plugged the WDCT antenna into the TCU the same as Ace but it only fits one of the 4 connectors with its original coding shroud on. WDS says the BT antenna should plug into X13383 which is the one next to the GSM antenna with the 'Blue' coding. is this the BT antenna? I think I may have it plugged into the wrong one!

Cheers!
