Hi all,

 

I’ve developed a slight issue over the last couple of days. I’ve seem to have lost heat through the rear centre console vents and the vent in the arm rest. It was fine till about half 6 the other morning. Heat then going down a hill and then cold. I’m thinking it may be a blend door issue on the passenger side. Passenger heating works as does drivers. 
 

I’ve had similar with the old 9-5’s but when the rear went so did the passenger side as it’s linked. Is it the same for the Superb? Never had the issue on all the other VAG stuff we have at work,

Do the vents under the front seats still blow warm air to the rear?

 

It may be worth trying to reset the heating and ventilation flaps, though I'm not sure how to do this as I've never needed to perform this function.  You should find it on the forum if you carry out a search.

I’ve got no heat on the floor vents either. I’m thinking as it tri-zone there must be a temp sensor in the ducting somewhere along the centre console to tell the system to heat or chill. I’ve not had chance to speak to my local TPS team to get diagrams or options of parts.

Have you pressed menu on the centre button of the heating and ventilation controls to see if it shows the temperature selected and red arrows for airflow to the rear?

All the menu system works as it should. All the way from Low to Hi. I’ve even locked off the rear, unsync’d the zones and individually altered. 
 

On the Saab system it would diagnose and give you a fault code to help. Wasn’t aware the Skoda system could do similar.

By the looks of it, the problem is the blend door motor. 
The car was throwing: 

B108E71: Servo motor for rear temp flap, actuator jammed.

B108E54: Servo motor for rear temp flap, no basic setting.

 

I’ve done a code reset plus actuator setting reset, while either holding finger around the actuator arm. Or manually adjusting vent modes and temp while looking at the arm. Nothing moves. Downside is that the motor is sat about 3 inches inboard of the passenger console edge. Looks like it’s a bottom of the dash off just to gain access.

 

Unless there is another easier way?

Hello Sir.

 

I have constant boiling air from rear vent and:

 

328451 - Motor for Rear Temperature Flap 
          B108E 13 [008] - Open Circuit
          Intermittent - Confirmed - Tested Since Memory Clear

 

328452 - Motor for Rear Temperature Flap 
          B108E 71 [009] - Actuator Stuck
          Confirmed - Tested Since Memory Clear
 

Could you please let me know the part number for this motor?

How much of the interior needs to be dismantled?

 

Thanks

Luckily for this one the entire dashboard doesn’t need removing.

 

but you will need to remove the centre console completely as it’s located roughly behind the heater control panel but access is limited.
