MFSW for Audi A6 C5 Platform

Part 1: Issue 1

Installing OEM Multi-Function Steering Wheel (MFSW) with

Tiptronic Controls and Heater into a post 2001 model year

C5 Platform Audi A6

Part 1: Research and Design

Part 2: Implementation Î to follow

Author: Bob Hawtin

Review Team: Lee Hicks and Ted Basile

Parts for Prototype supplied by: Martyn Franklin, Vagparts.

Summary

This document shows how owners of C5 platform A6 or allroad vehicles with an

Infotainment CAN Bus are able to safely take advantage of the all the valuable functionality

that a CAN Bus based multi-function steering wheel can provide. This significantly enhances

the user experience of the RNS-E and BT telephone installations that have been so

thoroughly documented on the Navplus.US forum. Most of the information will also be

relevant to the B5, D2 and TT platforms. It also applies to these models if you have a manual

gearbox and/or do not want a heated wheel. It does not apply to B6, B7 or A3 platforms.

If the MFSW system is not provided at the factory on an Audi A6 C5 platform there are no

components that support it included in the vehicle build. The work documented here is novel

and differs significantly from what has been recorded elsewhere by giving comprehensive

details of the research and design work required for implementation. Challenges particular to

installation in rest of the world models have been addressed as well as those for vehicles built

for the USA market.

Part 1 covers research and design

Part 2, to follow in late December 2006 will be a photographic record of the implementation

Please raise any comments or change requests via the MFSW C5 Research & Design Paper

thread in the Navplus.US Multimedia section.
