Agent 008 is not responding...

Hello!

After I successfully assembled the adapter that Ulf designed...
And as soon as I could, I got my Polo 9N running.
taken.

So far, everything is working as expected with the shareware version of VAG-COM.
as much as possible.
Okay, but now here's my problem: my Climatronic system has been acting up lately.
The fan control display consistently shows the required bars.
on, but the fan periodically oscillates between low and high speeds.
to a speed almost reaching its maximum.

It's only quiet when I manually adjust the climate control, but then it's noisy again after 2-3 [minutes/seconds - context needed].
I can switch back to 'automatic' mode after a few minutes of operation, and it usually works.
Then everything is as desired, but occasionally the device starts acting up after 5 minutes.
start playing with the fan speed again.

So, I was hoping to read the error memory using VAG-COM, but...
The climate control module (ECU) 08 is not responding. After some...
'VAG-COM asks if you want to continue attempting to access the control unit.'
to address the device. That won't achieve anything either.

I received the expression of interest from the workshop regarding the initial inspection there.
is the last entry:

6Q0907044A CLIMAtronic PQ24 0201
Coding 00000 PROG WSC 00000

Well, where it should say 'no error detected,' it's been torn off.
So, the workshop can access the Climatronic system, but I can't .

Otherwise, I can access all the control units, such as 01, 46, 44, etc.
just now, but not 08.

Does anyone have any ideas?

Most likely, the Climatronic system does not connect to the K-line, but is only accessible via the CAN bus, for example, using an adapter from Rainer's Diagnoseshop.

Yes, yes, brave new world - those who want comfort must also be able to endure suffering sometimes .
But at least now you can access the important STGe .

"My" adapter circuits, by the way, cannot be extended to support CAN (I certainly don't know how).

Yep, Ulf always has trouble with this modern stuff .

I was thinking something like a CAN bus .
Okay, I'll think about whether I should go to the new...
Order a suitable CAN interface for the laptop at the same time.
and I was so happy that I managed to get your adapter circuit working.
I have .
But for initial testing, it's definitely sufficient.

A CAN connection is not necessary in a Polo 9N.

Hello!

Oh, then there's probably a different problem here .
I have performed a self-diagnosis of the Climatronic system.
and there are 3 errors in the memory, but unfortunately, I have...
Don't sugarcoat it.

- 2c6 = ???
- 4F7 = Temperature control flap servo motor 0x25
- 4F9 = Actuator for central valve 0x25.

I have a feeling that '2c6' might have something to do with...
The connection between climate and the diagnostic interface has something to do with .

I've already scheduled an appointment with the dealer for Tuesday, as there's still availability.
The vehicle isn't that old; let's see if they can access the error memory.
can be read correctly.

Oha, I completely forgot about the CAN / K-Gateway .

Then, of course, the climate control system should also be accessible via the K-Line.
