Hey all, need some help with diagnosing cooling fans. Skoda Octavia 2013 mk3 ea288 clha engine :( Cooling fans don't run when the car gets hot, especially idling/traffic. The Dash gauge doesn't go above 90 in this instance, but the VCDS temp rises steadily above it. If I switch the HVAC on radiator fan run. When I run FAN VCDS output test, fan spool up, seemingly at a gradually increasing speed, to a maximum of 87.5% load. VCDS reads coolant temperature, it got to 101 deg C with no fans turning on (AC Off) before I switched the car off. Can't work out what's going on. The car seems to know the temperature of the coolant, but doesn't switch on the fans. Fans SEEM to work ok, because AC turns them on. Is there something else apart from the coolant temperature reading that turns on the radiator cooling fan? Thanks heaps. Sider
