Hello,

Today I was messing with my climatronic of my MK1. It has VAG number 7M0 907 040 AS (soft coding = 00014 and WSC = 00020). It has a code (for a long time already): 65535 Internal Control Module Memory Error. I don't know what it means.


I tried another control panel, a newer one: (just because I had it) 7M0 907 040 BG. Then the code 00792 A/C Pressure Switch (F129) came up. (and I already knew there was a problem, display was flashing and there is a crack in the pressure switch and it leaks oil so that's a fix for in the next weeks). I took this module from a late MK1 tdi from the scrapyard. the codes are: soft coding = 00003 and WSC 00021. (the rear blower doesn't work with this one, maybe because soft coding is wrong here?)

Could these two codes from the two different controllers be related? maybe the description got more specific on the later models?

But also: does someone have a list of al the codes from soft coding? and the workshop codes? It would be nice to have more informaton about these modules.

thanks in advance  :)

well... I found the most important information on a German variant forum in the mean time  :)

Would like to know more

this is where I found it.
this one isn't in the list: 000x? = 4 (I think this is specially for the 2.0 and 2.3 ford petrolengines. Just a guess!)
