Hi!
I have got a 2011 Audi A4 2.0 TDI 6-speed manual. The car works like a dream and has a perfect power delivery. The tune is a 177HP / 390Nm stage-1 tune.
While driving in degrees around or lower than -5C, the coolant will lose temperature if I'm not on the throttle. Meaning that if I'm coasting downhill for a few minutes with fuelcut and the climate control on 22C, the temp will drop to around 80C.
Then when the hill level out and I apply throttle, it quickly climbs to a 90 degrees and stays there while having throttle open at normal position. It has never in my ownership exceeded 90 degrees in any circumstance, even when +20c at wide open throttle on Autobahn, or revving it to 4,500 o/min in 25C.
As I mentioned earlier, the car works as it should and has a stable idle and great power response. But I wonder if this is normal, and if so - why? Is it simply because the climate control draws so much heat from the coolant while the engine is producing little to no heat?
Thank you for some clarification on this!
