s4 prefacelift dash retro fit - facelift mfd sat nav etc

[s4bush]

Right went to local audi last week and they said they used to do this for customers and have all corresponding paperwork and wiring diagrams needed to convert

Just picked them up.

Doesn't seem a massive task after skimming through the huge booklet they gave me.

So Far:

Parts Aquired:

Facelift centre cage consisting of climate control unit, mfd unit, all switches at top with all connectors, centre console surround trim piece.

Also audio and climate harness chopped from facelift A4

total cost £220

Issues to overcome:

fog light switch wiring
hazard switch wiring
can signal wire

Parts needed:

Gps antenna
Glovebox cd changer and cable
plug and play adapter /
conversion adapter (rns-e) maybe later

Will keep updated if anyone is interested

From what i remember, the hazard wiring is just a case of matching up color for color the wires between the old and new looms, iirc you have one wire left over but that doesnt matter.

The fogs need a relay from the facelift A4

can signal isnt required afaik, you need to connect a live to a certain pin on the climate units wiring to get the illumination to work but thats it.

Theres plenty info about this on audi-sport.net if you have a search over there.

Yep as u said u said hazard all done that was easy.

illumination worked 1st time

Dont suppose you know what relay is needed also Heated rear screen is where i'm having issues

Any ideas??
