HI
I hope this is not going to be a long and boring story, but here goes.
I bought my car from private seller. After i had bought it and sat in traffic jam for an hour the check coolant light came on. I topped the reservoir and hoped it would be all. Unfortunately not.
After days of driving i noticed that heat output to cabin isn't continuous as you would expect it to be, sometimes it blows cold, sometimes normal hot.
Sometimes it would also blow the check coolant warning. I wasn't able to diagnose where the coolant would go, but then i swa that i would blow it to coolant tank overflow.
Having suspicions i changed the cap and thermostat for original ones. That didn't help. I kept topping the tank occasionally when needed.
Few weeks back somebody wrote on our local VW-club that was like i've wrote it.

As you can see the temp. at t.stat housing drops, it's the exact time when i start maxing out my car. Also temp rises but heat in cabin stops.
When i arrive at home and keep the car at idle heat output doesn't restore. When i start revving it slowly restores.
Any ideas? Am seriously out of them. I'm afraid to have a bad Head or head-gasket, but if that's the case.

So today i took the car for testdrive/logdrive. The results via image are below:Problem started after WP and timingbelt got replaced. After change i was able to drive aprox. 50km(35mi) when coolant tank got empty. I added a liter and same occured after a while. This happened about 3-times. All summer long i didn't need to add anything.
Now in autumn when heat was needed, no heat would come, not even slightly. When revving up to 1500+ heat would come. When idling also no heat.
The company who changed t.belt blamed t.stat. That changed, car ran fine for 2 days. After that same problems occured. The company wasn't able to give a diagnose.
-------Few post between.
A someone who claims to be a experieneced said that this is definitelty waterpump issue and fault of not original WP. I will let the dealer to put OE WP.

Still some issue. Sometimes is heat, other times not.

I figured it out. I took egr cooler out of coolant circuit hoping that was problem, no it wasnt.
Than i took t-stat out. Heat in cabin all times, but coolant wont rise above 60C.
Ideas?
