D3 - Retrofit Bluetooth to Replace Fixed Handset
 

** Edit See page 7 for photo references **

Guys,

Just replaced my fixed Audi/Motorola phone kit with the bluetooth module from Audi. Not the rSAP unit by the looks of it, but still better than the one in the car as it wouldn't read any of the SIM modules I had (read my Dad's ancient Virgin SIM, so was actually working).

Anyway the kit I was supplied with had some cables attached and a 36-pin unit within the 54-pin connector for the module, the BT aerial and some MOST cables which it turns out I didn't need as I already had a kit in the car.

Fitting was relatively simple once I'd found the correct wiring diagram (thanks to Figure11 for pointing me to erWin) as all the documentation I could find on the web was for the US OnStar to BT conversions which have different pinouts.

Procedure:

1 - Unbolt the passenger seat. it doesn't need to be removed completely, just tilted back out the way (put the backrest forward and lift the seat base up to max for best clearance), you may need to wind the seat forward and back to access the bolts (T50).

2 - Remove the plastic trim along the kick plate next to the door. This just lifts up then pulls up and towards the back of the car.

3 - Unclip the seat power cable from the guide at the bottom of the seat.

4 - Pull the carpet forward from the air vent under the seat a bit, it's split at that point already, being careful not to strain the power feed for the chair which goes through a hole in the carpet about 6 inches in front of the split.Then lift the carpet from the door side.

5 - Unclip the seat power from the holder under the carpet and push the carpet back towards the central column (using the seat rails to hold it out the way).

6 - the Car Kit is in the box to the far left nearest the door hinges, pop it open and disconnect all the cables.

7 - Get the 36-pin connector for the BT kit, and the 42-pin connector for the old kit side by side and pop the followin pins from the old connector into the new positions on the old connector leaving the rest behind.

OLD - NEW
33 - 14 - Diagnostics
42 - 11 - MIC +
41 - 12 - MIC -
15 - 10 - Terminal 31 (or Earth to the rest of us)
16 - 2 - Terminal 31
35 - 1 - Terminal 30 (or +12V for real people)

Pin 3 on the new connector is a 'remote on' for the aerial amplifier which I don't think I have as there was no associated cable on the old kit as it had a built in unit.

8 - Connect it all back up: BT aerial, MOST loop, 54-pin

9 - Test! Sit back in shock that it actually worked

10 - Re-assemble. - Close the unit's box, refit the carpet while clipping the seat power cable back in, put the door trim on (be careful not to break the clips!) and re-bolt the seat down.

11 - Enjoy your new bluetooth car kit.

It's a hoot with the SDS module, taking 5 minutes to dial a number Much quicker with the turney knob thingy or just use the phone to do it.

Still to do:

- Remove the old phone handset from the centre console.
- Fit some USB sockets in there to charge my phones so I don't have the cable trailing around.

For reference this is exactly the same pinout diagrams for the rSAP compatible modules as well. After I trawled through and double checked :D

Just buy part number 8K0 051 592 for the 54 pin connector to make it a tidy job.

Does anybody have the part numbers needed to swap over from the fixed handset to the bluetooth ?

I'm not bothered about the rsap functionality, I just want to be able to pair the phone with the car and use the MMI / Multi func steering wheel.

ETKA isn't too clear and Audi are clueless, all I got from the parts chap was "that wouldn't be an Audi approved upgrade !" :ROFL:

You can use quite a few modules in all honesty, Mine was a Q7 one. As long as it's for the early MMI high systems (Not A4) from an A6, A8 or Q7 you are generally fine.

Then rerun your 5570 updates through to ensure all is well.

Thanks, none on eBay at the mo so will keep looking.

Looking round ETKA it looks like I need 4E1 862 335, does that part number look right ?

If so what other bits would I need to install ?

I'll give TPS a call to get a price - I'll sit down before dialling :D

You could also try craig @ tclsatnav.com for a fitted price.

Or kufatec.de

Assuming it comes with the connector block, you need nothing apart from tools.

TPS will order you connector block, very cheap. £1 I think!

Hi All.
Currently figuring out what parts I require to do the same thing. Replace the fixed motorola bluetooth with a non-rSAP factory bluetooth module.

Just not clear on what is required as far as the connectors are concerned. Would probably be clearer when I have everything laid out in front of me, unfortunately we don't have an Audi dealer nearby to order the required connector from so I need to do it in advance.

Where I am confused.
The motorola module has a 42-pin connector
I assume the new module has a 54-pin connector.

What is this 36-pin connector mentioned earlier? Is it some adapter that was included in the car of the OP and I don't need to worry about it?

I'll most likely be ordering a reversing camera retrofit kit from Kufatec so might try to order this 54-pin connector also. (just the connector, not the BT kit)
Would it be the 8K0 051 592 mentioned earlier, from what I have seen, that is a harness for the AMI, prob has the 54-pin attached also. Can the 54-pin be ordered by itself?

Sorry for all the questions. Just want to get it right and not have to be waiting for further parts down the track.

Also, are any changes required within VAGCOM to let the car know the motorola is gone and replaced by the standard BT kit?

Cheers

Although it's a 54-pin on the unit itself, there was only a 36-pin connector in the plug, sounds crazy, but the other pins aren't used anyway.

Car regonises the unit straight away, but you may need to go in with VCDS and let it know it's a BT kit rather than the Motorola.

I have started to install the bluetooth unit and have got stuck very early on - I will be missing something very obvious. :Confused:

I have the cill trim removed, the trim over the bolts at the base of the seat, and the carpet lifted around the air vent. +++

Where I am stuck is removing the passenger seat. I have found 2 black T45 bolts that do not let me remove the seat as these are too high up. I have also found 6 T40 bolts that look like they attach the seat to the top of the rail (under the small plastic trim). Is it these 6 bolts that need removing as they are very tight and I wanted to be sure first as I cannot see any T50 bolts. Removing these bolts will leave the rail in place assuming that these are the correct bolts.

Can you point me in the right direction?

Thanks

Gday mate. Just a quick reply as I'm sure you want to get stuck into the job. I don't have my car here so can't go and double check but from memory there are 4 covers where the seat joins the car. These slide off and caused me a bit of grief figuring out that they slide off. Beneath these are the bolts you want to remove. The seat frame stays attached to the seat. There is a harness beneath the seat you will want to remove to allow enough cable length for when the seat is tilted back. Good luck. :-)

Great, thanks - I will go and look for these slide-off trims. Last thing I want to do is start undoing random bolts.

Found the bolts - Got 3 off them off and found that the last bolt is already rounded. No matter what I do, my T50 will not work as it rotates on the slightest pressure.

I can only think that I will have to trash the bolt and get a couple of replacements. They do seem very soft though. Looks like it will take somewhat longer to do this little job......

Right, I finally have the new bluetooth unit in place with the seat removed. I will get hold of a couple of replacement bolts for the seat that were damaged.

There is a pink connector that I have disconnected from the old motorola unit, what is the pink connector that I have removed as there is nowhere for it to be plugged in (My guess was the console handset)?

The main connector is not compatible with the new unit. Am I short a conversion cable/block?

You do need to change the connector on the loom, i followed the instructions in the OP

http://forum.a8parts.co.uk/showthread.php?t=908

Pull the pins out of the old conneCtor block and put into the new one in the relevant posuitions, Followed by an mmi upgrade

^^ What he said.. Unless you didn't get the new connector block :(

The other connectors down there are for the aerial and the console handset which you don't need.. And you can remove the console handset to get some cubby space back.

I did not get the new connector block. :( is there a part number for this?

I have connected the original yellow connector lead into the new module - I was assuming that this is the bluetooth aerial, or is there a different part needed here too?

I must admit, i cant remember the colours of the connectors, but he bluetooth antenna is a small black tab like object about 2 inches long and doesnt connect to anything else.
The connector block i ordered is 4e0 972 144 and it cost 2.34

ooh, I don't have an independant bluetooth antenna - Found one on ebay 8P0-035-503-E

Yep, thats the right antenna. I have found the original guide with which I also used
http://www.audiworld.com/tech/elec133.shtml
Its for a D2, so the pinouts are not correct for a D3 (use those in the OP instead)

Thats the one I found to get the code for the antenae. What caught me out was that I expected the original connections to have an antenae. I was expecting the yellow plug to come off the old module and straight on to the new module.

Do you know what the original yellow plug is for?

Not off hand, ill have a look to see if etka has details. I think the purple one connect to the antenna amplifier, which then goes to the roof antenna

Pretty sure the original had 2 antennae connections where the new one has none (unless you have an rSAP module)

As I have had to drive the car with the install only 90% complete, why does the MMI not run? The optics are in the module, but the loom is not plugged in. Surely this cannot confuse the system that much.

im guessing by having no power you have a break in the most ring, so sounds probable to me, one of the experts will no doubt be along shortly to confirm

Exactly that.. If any module in the loop fails (or has no power), the whole loop is down.

MOST annoying . . . . ahem. . . .I'll get my coat :p

Very... if something daft like tv tuner fails, then it's all dead :(

I have installed the bluetooth module, new connector and dongle. The MMI recognises that I have bluetooth and allows me to delete pairings and change the code. What I cannot do is pair my iPhone 3GS with it - The iPhone does not find the car.

Could this be due to the MMI software version? I am on a lowly 2120.

Probably, you can get a backup from the dealer, ebay or google "E73A79E9B4FE02DFEAF53176A13AD9C93B5B20D2"

I have looked at everything left to do. I do not have access to the hidden menu, I need to get an update CD (Don't trust Torent sites) and I will have to make sure that I don't lose any modules in the updates.

My car just says:

Your telephone may not be connected or attached properly.

I am currently hoping that this only means that the software is too old as my iPhone will not connect. Maybe I will see if I can dig out an old phone from a drawer and see if it will talk to that.

Is the only real way to sort this by taking the car to the Dealers at great expense?

i would say you defo need an update to the latest version, but try anyone else phone you can get hold of as a test, dealer will probably charge you 2 hours labour (about £240) or you can order the disks from audi at £5.20 and do it yourself, you are likely to get a component protection issue pop up (mine was the bose ithink, it would only get sound from one side of the car) the dealer should get rid of that in half an hour and £25

I have just tried an older phone to no avail. I would be fine running an update myself, but do not have VAGCOM or VCDS (I think I got that right) to enable the hidden menu, or to correct any modules if they go into protect, or get disabled.

I will have to see what the dealer says on enabling this for me. As the nearest dealer is 50 miles away, and they are poor at completing work in a timely fashion, waiting for the car would be a bit of a waste of time, plus I am never available during the day to give them the car.

I found mine sometimes only paired right after an MMI reboot ('tel' + big knob+'top right meta key') then try to pair.

Im only in Leeds, not that far if you want any vagcom work done. unfortunately im now in france for a couple of weeks, but happy to meet up when i get back if your still in need.

you should be able to get the dealer to do an update while you wait though.

I'm in Stokesley, North Yorkshire :) Happily help you with this.

Or I can upload the update if you want to my website? The discs have a checksum on it and won't work unless they think they are 100% original anyway ;)

Never seen the CP mode, except when I went from very early software. I just carried on with the upgrade and it pulled itself out of it. Done it on 4 of my 5 cars now.

Thanks for the offers guys, I may look at this as soon as I have chance.

I do not get a bluetooth symbol on the MMI screen so I am guessing that it does not realise that I have upgraded the module so it is not trying to find my phone. I think this is where I need the VagCom help. Also, with my B&O problems, there may be a chunk of error codes to laugh at.

Just fitted my rasp module this morning in my 54 plate PF 3.0tdi, firstly a thanks to this thread and the OP made a huge difference having the pin outs to hand, on another note I had the old Motorola unit swapped over and car back together in less than 30 minutes ;)

When trying to suss out my passenger seat issue I needed to get to the circuit breakers in the passenger footwell, whilst doing this I found the Motorola module, you don't need to remove the seat, just remove the kick panel and lower door trim that's all one piece, grab the carpet from under the dash on the left hand side and pull back and over to the center console, this gives you enough room to work inside the box and get the clips undone to remove the cover, it's a lot less faff than having to unbolt the seat and everything, carpet goes back fine and I now have hands free again :)

Bluetooth module not working
 

Hi Guys,

My car has a working Motorola Factory installed handset. I had also recently updated the MMI software from 0290 to 5570.

just bought a Bluetooth module from a Q7 on ebay marked 4E0 862 335 and SW 4E0 910 336 h 070.

I did the wiring changes as described in this thread and connected the unit up.

My MMI tells me it can't find the telephone when it starts (after about a minute). I tried restarting the MMI and I've coded the control module channel 12 for option 2. Restarted the MMI and it still tells me it can't find the telephone.

VCDS tell me that unit 77 is unreachable.

If I disconnect the MOST cable while the 54 pin connector is plugged in I can see light coming out of the cable on one side and out of the module on the other side.

If I go into my hidden menu and look at TEL FBLOCKS it reports "Telephone not yet unlocked!" Could this be a component protection issue? I would have expected the module to still respond to VCDS even if it was in component protection.

Is this module suitable for my 2003 D3 or does it sound like it is faulty?

I have rewired the unit back to my original factory fit module to get a working phone system again so I probably wont be able to check until next weekend.

Some pictures of the unit and wiring here:

I've double checked the wiring and it looks fine to Me?

Any help greatly appreciated
Thanks
David

Hi, run the MMI DVD again, twice. Sounds like you upgraded the MMI before installing the module, so the Bluetooth SW may need upgrading. The Bluetooth module on mine and many others' required the DVD to be run twice.
