Flat bottomed steering wheel

The obvious starting point is Ebay - budget around £400 for a wheel and airbag (normally from Germany/Hungary).

Any current Audi flat bottomed wheel will fit, so that's TT, S3, R8 - you could even fit an RS4/6, but they don;t have multi-function capability.

The bluetooth module is another £400 fitted from a friend of mine the other side of Manchester (he does ICE stuff around Manchester and I do cruise fitting).

Then, you'll need about another £250 worth of parts to create a multi-function system, capable of talking to everything via the wheel - the A2 standard one won't work, as the A2 doesn't have a LIN bus, unlike all newer Audis (the ones not using MOST bus that is!).

Wiring wise, you'll have to mod the airbag loom and also create a new multifunction loom, tied into the CAN bus and various other points - not easy by any means, although it is possible as I have demonstrated.

cheers skipton,
Sounds good, Ive allready spotted a couple of tt flat bottom wheels on ebay, As for the bluetooth module im not too concerned about right now as i will retro fit that latter, i will be useing the Ptt button on the mfsw to control the speech dialouge system (SDS) on my rns-e.

So to begin this project i will require a mfsw with airbag (is this a single stage fire as the standard or a dual stage?)

To control the mfsw i also require a new slip ring??? would this be the tt one?

The only thing bothering me is the wiring, mainly the multifunctional wiring loom. can this be bought form a dealer then modded? how difficult i the airbag loom?

As to the slip ring, you can use an A2 one that is fully wired, front to back - you may find that your current one is suitable, mine was.

Simply put a meter across the contacts at the front and back and see how many pins have continuity - you'll need a minimum of 7.

After that, you'll also nee an A4 steering electronics module, to provide the necessary communications to the RNS-E and then a custom wiring job (you can't buy a loom - it has to be made from scratch).

Cheers,

Mike
 
Am i correct in believing if the slip ring has all the pins not just the air bag pins then i have the correct slip ring. should that be 7 pins on the slip ring that a are connected from the front of the unit to the rear?

could you please give me a part no: for this A4 steering electronics module? (is this the box that look like a relay?)

As for the custom wiring any chance you got a circuit diagram so i know what to connect where?

Thanks skipton, im very excited about getting this mini project started deffinatley a mod worth doing especially for the sds control and then for the bluetooth (later)

P.S. 1 last question the original airbag has one connector and the newer one has 2 so how was this rewired, i would have thought you split the original connector to power both connections on the new airbag. is this correct?

Unfortunately, the pins being there is no guarantee of continuity - you need to put a meter across them all.

The A4 module is 8E0 953 549 R and looks like an uneven horse shoe. As to the wiring, you really need access to a set of wiring schematics and work it out from there - what you'll need to hook up is the LIN bus parts of the A4 steering module, the CAN bus section and then tie these parts into the A2 CAN bus system and steering module.

As to the airbag rewire, it's not that straightforward. If you want me to do it, I will (as I have done for Chucknaldo and PC759), but if you choose to go it alone, PLEASE BE CAREFUL - YOU ARE DEALING WITH A SAFETY CRITICAL PART OF YOUR CAR.

cheers skipton,
At present i am in the process of gathering the parts ive seen a few steering wheels on ebay and i will probably only find the a4 mfsw controller at the dealers. what is the price of these controllers?any chance you still have these wiring schematics??
 
A4 unit

8E0 953 549R £94.54+vat

This is what I was quoted by vagparts.com (including my A2 owners club discount).

Haven't bought one (yet) ;-)
