Hello everybody,
After many years of hearing about VCDS, I finally have a (new to me) 2012 Passat NMS SEL VR6. First a bit of history: the car has 160k on the clock and was decently maintained (and absolutely beautifully cleaned and waxed regularly) by the prior owner, who had it since new. I took possession of the car a few weeks ago, and quickly noticed the heater output was middling, with different temps on driver and passenger sides.
This is the dual-zone Climatronic.
At the time I hadn't gotten my VCDS yet, but found many posts about clogged heater cores and the relatively easy replacement. So, I ordered a new core and went about installing it. Long story short, I botched it and mangled the heater pipes, so I wound up removing the instrument panel. Out came the air distribution box so I could replace the metal lines, and I put it all together again to find...the same tepid heat!
I'm satisfied that the core is working fine -- both pipes are HOT to the touch, with no detectable difference between them. Coolant level is stable, so I don't think it's air bound.
So, after the work, the performance is the same as it was. I don't think it's changed by the work I did.
Finally got my VCDS last week, and got the codes from the car. There were a number of codes initially, mostly related to the car's confusion after the work I did. I cleared all codes first, then re-ran the Auto-Scan several times. Here's what I'm left with now:
Given the number of sensor codes, plus the engine and central electric codes, am I on the right track thinking this is likely an issue with wiring or a module somewhere? Perhaps the Climatronic control unit itself is on the fritz? Curious what the experienced among you may think. It seems unlikely that both right and left temp sensors, for instance, would both be bad at the same time. But I'll believe anything!
I'm an experienced shadetree mechanic, having learned my way from a couple dozen 90s Saab 9000s, plus a couple E34 BMWs and a few other patients. However, I recognize my limits, and I have gotten away with throwing parts at the problems for the most part. Now I expect it's time for me to learn how to wield a voltmeter and obtain the art of electrical fault-finding! So, any recommended study materials and vids would be most welcome.
To finish off, the VW is with my parents in Connecticut -- who will be driving it locally for errands -- while I live in Brooklyn, NY. So there will be a long delay before I get to try my next approach. Before I captured this auto-scan, I have cleared all codes a few times, performed the vent adaptation (performed via VCDS and also via the Climatronic unit) successfully, and obtained the reported temp readings from the left and right vent sensors -- 85C (!!!) for both. I also uninstalled/reinstalled the Climatronic unit and double-checked that all connectors were solid, then cleared and rescanned again.
Again, I suspect nothing is different as a consequence of my work. Everything is connected properly, and I don't think I damaged any wiring during the work. It seems the heat is about as it was before I dug in.
Sorry for such a long message, but I'm very excited to learn more about VCDS and my Passat! Luckily, there is heat, just not great heat, so my parents won't freeze to death this winter, and I can take a careful and reasoned approach to diagnosis and repair. At least going forward, ha ha!

Given the number of sensor codes, plus the engine and central electric codes, am I on the right track thinking this is likely an issue with wiring or a module somewhere? Perhaps the Climatronic control unit itself is on the fritz? Curious what the experienced among you may think. It seems unlikely that both right and left temp sensors, for instance, would both be bad at the same time. But I'll believe anything!
I'm an experienced shadetree mechanic, having learned my way from a couple dozen 90s Saab 9000s, plus a couple E34 BMWs and a few other patients. However, I recognize my limits, and I have gotten away with throwing parts at the problems for the most part. Now I expect it's time for me to learn how to wield a voltmeter and obtain the art of electrical fault-finding! So, any recommended study materials and vids would be most welcome.
To finish off, the VW is with my parents in Connecticut -- who will be driving it locally for errands -- while I live in Brooklyn, NY. So there will be a long delay before I get to try my next approach. Before I captured this auto-scan, I have cleared all codes a few times, performed the vent adaptation (performed via VCDS and also via the Climatronic unit) successfully, and obtained the reported temp readings from the left and right vent sensors -- 85C (!!!) for both. I also uninstalled/reinstalled the Climatronic unit and double-checked that all connectors were solid, then cleared and rescanned again.
Again, I suspect nothing is different as a consequence of my work. Everything is connected properly, and I don't think I damaged any wiring during the work. It seems the heat is about as it was before I dug in.
Sorry for such a long message, but I'm very excited to learn more about VCDS and my Passat! Luckily, there is heat, just not great heat, so my parents won't freeze to death this winter, and I can take a careful and reasoned approach to diagnosis and repair. At least going forward, ha ha!
