Climate into RHD avant

[S2central.net]

RIght then - had a quick squizz at MY98 B5 platform ACC diagrams - W chassis Audi A4 - and they are different from earlier years. One notable difference is with the blower motor & control. On MY98 its an integrated 5-pin affair. Some wires are same purpose, some are not. Seems the 5-pin affair was used on MY97 setup as well.

You would need to be careful when mixing and matching looms, head units and such to get it all compatible.

AFAIK - the early A4 loom is functionally the same as LHD S2/RS2 climate loom but you would need to modify it along the way.

I will endeavour to get a good review of johne's guide to see if I can help unravel any wiring mysteries... What I mean is that his guide may not be valid for a conversion from an MY98 vehicle due to these few wiring differences - above and beyond the V2/J126 integration.

if you have the diagrams for A4 on a W VIN that would help lots

cheers

I should be able to sort out A4 W VIN diagrams. Is it just the climate you want? PM me you email address and I'll sort it out.

I do but they are on paper only and might be US specific... Will try to do that tonight sometime. PM to remind me

Don't miss a trick here... that website covers other cars and years - look for Auto Climate in a 1995 Audi 90 and you should have the LHD B3/B4 platform with climate to compare in same format to early B5 (Audi A4).

Oh those aren't official Audi diagrams by the way - some schlonky aftermarket Russian format I've seen before - not as friendly as Audi style - damn

OK - now it makes sense... will download, print and ponder for a while.

My blower drive output is on pin C16 as johne's list not tthe above diagram
But my fan speed monitor is on C11

WTF - I never studied Russian at skool

I cannot even see a link to that site in Engerlish

looking like this 1997 diagram has some diffrences to my loom out of a VIN number W car

The supply to C13 is a peranent supply from the digital clock curcuit and is not needed on this controler it retains it's memory when the the unit has no 12v feed.

What wiring diagram are you working from here - is it online somewhere ?

I have Bentley US schematics for the A4 and obviously all the 80 diagrams so we should be able to nail this one.

Just looked at the 1997 diagram and compared them to johne's. They appear to be the same in all aspects except pin A11 this goes to the instrument cluster in the A4 where as johne took it to T5h pin 4. I'm struggling with the blower wiring at the minute. it appears from the diagram that the live supply to the blower is cut when the low pressure relay is denergized, so if your a/c lost gas your blower would not work

Also my loom dose not have a C13 live supply could be nothing, could be a headache

Seems like an early A4 (MY95/96) donor is a simpler conversion then. The best option for CCU is from European Audi 80 with climate - that can be coded perfectly for RHD 5-cyl... I suspect other CCU from early A4 and 100 models can be used too though its been a long time since I looked into this one. Johne did a lot of great work here so I would defer to his guide in the 1st instance.
