PROBLEMS: RNS510, Bluetooth, Steering wheel buttons, airbag fault

[DragonzBreath]

So looking at the image in the earlier post, I see byte7 has main bit 0 on for the working one (i.e byte7=82 for working, =02 for not working). Did you enable this bit, and then do the <>* reset thing? Looking at bit 0 of byte7, it is certainly for the steering wheel controls... (might have mixed up bit 0 and bit 7, but both bit 0 and bit 7 are related to steering controls, so will be one of em hehe).

I've changed the coding on the revision B unit to be the same as the revision C aside from byte 8 which isn't codable. It does not resolve the problem. I did not however do hardware reset. I find that when I do that the B revision unit 9x out of 10 asks for an SWL CD. From memory Byte7 coded with 82 enabled BAP. I'll try it, but I don't think it'll resolve it, I think it's been tried before.

Make sure you take a copy of the coding first, then you can try and add the missing byte to the RNS510:

Add 2 zeros to the end of the coding (not in long coding) and click 'Do It!' Ignore warning.

Do a reset to the unit with < > and *

Go back into the coding and apply full coding with bit set for BAP.

Reset the RNS again.

Oddly enough, I did this last night but it didn't work, I'd imagine because I hadn't reset the head unit. Anyway, I had the head unit on the passenger seat over night, when I got in the car to go out this morning I realised I hadn't put the car back together. I chucked the revision B head unit back in and the buttons are now working.

The telephone buttons still do not work. The coding is as per the instruction manual for the unit.

Golf is out at the moment I will see if I can get a chance to check coding later this evening.

Can't actually compare coding directly with my Golf as it has a 3rd party nav unit with BT integrated.
However as you have most other functions working my guess would be that your address 77 Telephone coding may not be 100% correct.

Failing that raise a ticket with Rosstech. They are very helpful.

Airbag fault

Hi, re your airbag fault. I had a side airbag fault in my B6 Passat and I did a lot of research before I took it to VW for a big$ fix. A very common problem is the connections under the front seats. The recommended fix is to cut the plug out and solder the wires together removing the problematic yellow plug from the system. I took the passenger seat out and what do you think I found? The yellow plug was dissconnected. I pluged it back in, cleared the code, rescanned, and no more airbag fault. Befoe you do anything else, I would undo the seat bolts and tip the seats back so you can get to the yellow airbag plug. Try the passenger one first. If the plug is connected securely, unplug it and spray it with some CRC CO Contact Cleaner. Give it a few minutes to dry then plug it back in and clear the code and rescan. If it comes up again, do the same with the driver's side. This may not fix your problem, but from the research I have done, about 80% of Airbag faults are triggered from these underseat plugs. Apparently they get moisture in them and start to corrode. Good luck mate. Cheers.

Bambazonke, are you able to answer phone calls with the buttons on your steering wheel? I'll have to see if mine now work...[/QUOTE]

Yes I am able answer and terminate calls via the telephone button the steering wheel. I also think I can reject a call by holding it down for 2 secs or more but I have yet to test it

Steering wheel phone button not working

Hi DragonzBreath,
I suspect that your premium Bluetooth may not be compatible with your MFSW (Multi Function Steering Wheel) module. The older 8 button steering wheel modules uses LIN 1.3 rather than 2.0 which the newer MFSW uses. I have the same problem. I have a 3CO 953 549 AC steering wheel which uses LIN 1.3 but the 9w7 bluetooth unit I installed needs 2.0 for the phone button to work. If I had an AH or AK 8 button, I wouldn't have the problem as they use LIN 2.0. My only option is to possibly change the MFSW module but that could create other issues I believe. At the moment I have phone on the RNS HU and on the MFD and Voice control, volume etc on the steering wheel. Just not the phone button. For the time being, I,m not going to worry about changing the module. I'll add the link to a MFSW module compatibility list. Find out which SW you have and check it on the list. I suspect it will be 1.3 not 2.0. Cheers.

Steering Wheel Control Module Versions - Ross-Tech Wiki

[DragonzBreath]

Thanks for that, I actually upgraded my steering wheel, but the steering wheel I got was from a newer model GTI, which had a highline dash and the buttons were different. So I swapped them out with the buttons from my original wheel (sorry forgot to mention that).

The MFSW part number for my car is 1K0 953 549 B, which is indeed LIN1.3

The Bluetooth device is I believe a standard bluetooth kit (1K0 051 437 A), rather than a premium one. Although I wouldn't mind upgrading. Because I've already got the wiring in place, is it as simple as purchasing a new bluetooth module, swapping it out and recoding? Or does the premium module have a different connector?

Thanks again.

P.S. I ALWAYS have to do 'Image Verification' every time I post, is this normal? It's annoying.

The number above refers to the kit number, the BT unit you have is 1K8035730B which is the basic 9w2 unit. From what I have seen on eBay the wire looms are the same for the 9w7 units but vary slightly if you use the voice command function on your navi unit which I understand has it's own microphone. You can always try and buy a module on it's own and if not successful,buy a loom separately although it might be a bit more expensive than buying a complete kit upfront if the loom is not compatible.

[DragonzBreath]

Thanks Bambazonke. From what I've seen bluetooth units in most Golf's are installed under the seat. Mine is in behind the head unit. I don't suppose that will be a problem?

Also, I contacted RossTech a few days ago with my phone buttons problem on the steering wheel, I'm yet to get a response. Are they usually quick with their responses?

[DragonzBreath]

So I got a response from Rosstech today...

The new 9W2 style of Volk-L VW accessory 77 module appears to be coded
properly at 412120. You could try to code it to the alternative 402120
for BT media inactive functions as a test when answering calls.

On that note, please realize this unit does not support voice
recognition or PTT so the only function of that button is for answering
calls that are ringing already -or- to hang an existing call up. If you
were looking for functions when the phone and radio are not in use, that
operation would not be supported with this particular system. Although
this is quite old, the functions are covered in this thread:

VWVortex.com - OEM Bluetooth System should be available by Oct 1 - 1K0-051-437


G179 is a crash sensor mounted inside the driver's side door and
was never related to the driver and passenger side bag igniter fault
repairs under the seat. Due to the Open or Short to Plus description
that sensor may be internally faulty -or- the wiring to it may be
faulty. The early Mk5 models in the US market were known for breaking
wires off at the door pivot points so check the wiring per the wiring
diagram to/from the sensor not only inside the door but at the moving
harness section as well.

Glad I got that before attempting the under seat repair. I now know I don't need to. But the alternative of broken wires where the door pivots is going to be a real pain. Does anyone have information on fixing this?

Hi. Did you ever get your steering wheel buttons to work? I'm having the same problem.

Here's the fix:

Note! Skoda owners

Extract files PQTABLE and SKTABLE from image (use magiciso or ultraiso). Files can be found from path: \VUCI\B101\RNSMIDEC\PROG
Switch the filenames by just renaming SKTABLE to PQTABLE and vice versa
Overwrite the renamed files back to image and save the image. Burn this image to DVD or CD.
Load or reload the Firmware to your RNS-510 using the steps below.
Voilá… buttons are back!
