Hi I have a 2013 1.2 tsi seat Leon my heaters seems to blow out like 40percent hot air when on the hot setting set at 1 if I put it to 6 then it’s just cold air. If I leave the heaters off for a couple mins either parked up or driving and then put the heaters back on it will give out full hot air for a minute or so and then after that goes back to like 40 percent of the power. Can anyone suggest what the issues could be, I’ve heard thermostat or maybe do a flush of the coolant system or heater matrix. My friend had a leon just like mine but 1.6tdi it wouldn’t give out hot air at all doesn’t matter how much he drove and his was heater matrix. If anyone can help I’d appreciate it thanks.
