Hello everyone, I'm looking for a possible solution to a recent problem I'm having with my A3.
It's a 2014 8V 2.0 TDI currently sitting at 163.000 km / 101.000 miles. Recently I noticed the coolant level not being consistent and no heat when using a/c.
I topped up the coolant to the "max" line (car cold) before a long trip I had to take (500 km / 310 miles). The next day (car cold again) the coolant was again under the "min" line.
Car was running fine the whole trip, without overheating with oil temperature in the 98-103 °C range (208-217 F). No heat in cabin the whole time.
I recently serviced the car and replaced diesel, air and oil filters, along with a full change of oil. Old oil was clean black and not contaminated - I'd exclude a failing head gasket.
Aircon controls works fine and putting it on max blasts cold air at full force.
Can't find any signs of leakage from the engine bay, might put the car up again and check from the underside.
My first suspect would be a clogged heater matrix. Any other idea?
