Hi, I've been struggling for the last week with a problem of the v68 motor. My car had the air conditioning not working for years now, it only blows hot or cold air. I wanted to solve it and so I watched the forum and I found out that the problem could be the v68 temperature flap. So I did a test with VGA and got these errors: 

01271 - Positioning Motor for Temperature Flap (V68) 
            30-10 - Open or Short to Plus - Intermittent
01596 - Motor for Outside/Recirculated Air Flap (V154) 
            30-00 - Open or Short to Plus
01271 - Positioning Motor for Temperature Flap (V68) 
            29-10 - Short to Ground - Intermittent
01596 - Motor for Outside/Recirculated Air Flap (V154) 
            55-00 - Adaptation Not Successful

So it looks like the problem is the v68 (also the v154 but the recirculation works fine so I don't care).

I finally got the motor out and tried it and actually the wheel only rotate when I put the temperature to the max or to the min. So I bought two different motors (they were used but they worked on the older car) and they have the exact same problem. I also did basic setting and cleared the fault codes. I really don't know what to do now and I'm not understanding if actually the motor should rotate like that or it should rotate also when it gets the inputs of the intermediate temperatures. Actually it works like the motor on this video but there he says that he solved the problem  Please help me

 

Also, I've just found a topic with my same exact problem: 

 

When I perform basic setting it stays stuck on 255 both for the v68 and the v154. I just bought a heater control panel (6Y0820045B, is that right?). Should I be fine now? and how can I check where the problem is?

I’ve had this on both my Fabia’s. It will require a new motor. It’s gone weak

Actually as I said I bought 2 more motors but they both works as my original one so I don't think that it is the problem

Are they new or 2nd hand?

Ok, bought and installed the new control panel and the the motor works a bit better (it works 1 time out of 3)... I really don't know what to change next... and vga still gives me 255 when I perform basic settings

HI Corby. 

 

I've searched a lot of forums for someone to describe the exact problem you have - I have the same issue on my 2003 polo, so this is probably breaking all sorts of forum rules (sorry!) , but the motor is the same (V68), and I also have removed the motor, and seen it move to one extreme when the temp setting is on cold, and move to the other extreme when the temp setting is anything else! . I think just like your video. 

 

I have also replaced the control module (thing with 3 dials - temp, fan speed, vent selection), and no improvement. Finally I got hold of the 'hidden' fault codes that are not exposed on a normal OBD2 reader, and mostly they match yours - 1271 temp.reg flap motor -V67 Short to B+ intermittent, or open ot short to b+ intermittent, 

 

The main question is - did you finally fix your problem? 

 

Thanks

 

This thread is nearly two years old and you've almost no chance of a reply now, these flap problems are caused by a faulty position sensor but you have to replace the entire motor assembly to fix it since the sensor is built in. Best to start a fresh thread if you need any other help with this.

Hi, OK thanks. Regarding the V68 flap motor - I have had it out, and 'cleaned' the position sensor (A rotary potentiometer) , with the output appearing to range between 0ohms and 5kohms when turned. Also the values as indicated on a VWTOOL page for HVAC does show the channel 7 value ranging from 20 - 2~30 smoothly when the motor is instructed to go from cold to hot. Potentially both of these are not showing where the problem really belongs!

Thanks

 

Have you tried adapting the motor now that you've cleaned the pot?

Hi, what adaptations are recommended? Visually, it all appeared smooth operation with the lid off the V68, but again maybe I missed something.

Adaptation consists of a software routine run in diagnostics so that the ECU can learn the parameters of the flap as installed to allow an algorithm to interpolate flap travel once it knows potentiometer values indicating fully open and fully closed. Much the same as the throttle body.

Hello everyone,

I know this is an old thread, but I wanted to share a solution I found for a tricky HVAC issue that might help others. I had a problem with my car's climate control, specifically with error codes related to the V68 and V154 actuator motors.

First, let's clarify what these are:

V68: This is the temperature flap motor that controls the temperature of the air coming into the cabin.

V154: This is the recirculation flap motor that controls whether the air is taken from outside or recirculated within the cabin.

My initial issue was with the V68 module (part number 0 132 801 207). A new one was way too expensive, so I took a chance on a different but similar part (0 132 801 357). The connector was different; it was a rectangular one instead of the oval one I needed. Fortunately, it came with a wiring pigtail, which allowed me to confirm the pinouts were the same.

Here's how I handled the wiring:

I carefully removed the wires from the old oval connector on my car's loom.

I then removed the wires from the rectangular pigtail that came with the new module.

Finally, I inserted the wires from my car's loom into the new rectangular connector.

This fixed the V68 issue, and the motor came to life. However, I was still getting V154 error codes, and the V68 module was only working at maximum hot or cold settings, with no in-between. This had me scratching my head for a bit.

After some more searching, I realised the problem was that I had two separate issues, not just one. I found the V154 module, I already had a spare part for this since I had accidentally bought the wrong one for the V68 initially.

I swapped out the V154 module, ran the basic settings adaptation using VCDS and everything started working perfectly.

The main takeaway is that if you're getting multiple HVAC codes, you might have more than one failing part. Don't assume a single fix will solve all your problems! But if I'm being honest I wonder if the V154 was the issue module all along as it seems like they work in tandem.

Red is where the V68 module is located and blue is where the V154 module is.

I hope this helps someone in the future.
