In the SEAT Leon 1.6 TDI with dual-zone climate control, a heating issue in the cabin has been observed:
Main symptoms:
The heating works normally only on the left side of the cabin, while the right side heats very little or not at all.
A gurgling noise is heard in the cooling system, similar to “air in water” in a radiator.
When trying to use two heating directions at the same time (e.g., feet and dashboard vents), the heating power weakens or stops completely.
If only one direction is selected, the heating power returns to normal.
Any suggestions?
