Pinout for Climate Control Unit?

[Nozemi]

Anyone happen to have a pinout diagram for the climate control unit or its wiring harness? I tried to look for it, but couldn't find it.

If it matters, I have a unit with dual zone controls (8E0820043 afaik). But pinout for any variant for the B6 is probably nice to have anyway, if there are multiple pinout variations.

I think I have something similar to your request but it might not be precise enough for you.

Doc is in french, so I copy paste it here. It's easier for you to use google translate after.
If you want to look for the document in English, you should search for SST 254.

Thank you! It might not be exactly what I need, but it certainly could prove to be useful. :)

The document in English can be found here for anyone needing it: http://www.volkspage.net/technik/ssp/ssp/SSP_254.pdf

This document apparently was for a B7? Unrelated to climate control but interesting to see on page 22 that the dual side mount intercoolers have a separate high-low bypass through each intercooler so that the charge flow is more or less routed in parallel through working area of the intercoolers instead of in series. I am thinking that the USA market B7 intercoolers Ive seen each only had 1 inlet & 1 outlet so this feature might not have been included here?

It's for a B6. It says '01 and the drawing is a B6 + the engines are B6.
At least in Europe, the B7 only had new gen diesels so 2.0 TDI, 2.7 TDI 3.0 TDI so it's probably why it's different from what you've seen.
+ Based on page 22, it seems that the B6 had 2 different types of intercooler systems aswell on the 2.5 tdi.

Any explanation of why they refer to the 4-cylinder as a 2.0L and not 1.8? Was there ever a 20-valve 2.0 actually produced or maybe they had plans for a bump up in the displacement from prior B5 and then just left it alone?

[bab73]

There are 2 different 4 cylinders naturally aspirated 2liters on the B6. We had both in Europe, I don't know for US.
A 2l 130hp, 20v, so probably derivated from the 1.8(t). Based on the power sheet it is this one in the SST 254.
And the 2l 150 FSI, with 16v, probably the NA version of the 2l TFSI that you can find on the B7.

THanks, I did not realize availability of other 4-cylinders offered elsewhere. USA only got the 1.8T (and V6) for B5 and B6.

Here's a quick pinout I just made, you guys should reeeeeeally learn how to read the erwin diagrams

[Nozemi]

Much appreciated!

Also, I totally agree. Any pointers to get me (and other fellow noobs like me) in the right direction for learning how to read erwin diagrams? Also, to avoid confusion; an erwin diagram, is that what we were referring to from the SSP?

take a look at this to start
