In my case no, at first I was thinking I am loosing that way, but, later on when I was inspecting it more, it wasn't the case... If your car is spilling it out of the closed expansion tank, your problem could be with heat matrix core in cabin... But just to be sure, try checking both the chargecooler and egr cooler too... Those are 3 options you can firstly try, and also the cheapest possible cases... Oh, yes, I almost forgot, you can try putting a new expansion tank cap, from friends car or something like that... This is some begininng notes I can give you...

Hey Joypower, yes, chargecooler replacement solved my problem... Make sure you buy yourself intake manifold gasket too, they are pretty fragile, at least mine was! Good luck

Chargecooler changed, we will se if it's going to be better

My charge cooler has number 04L 129 766 Q, and I've found on the market 04L 129 766 K, is there any significant difference with them?

I didn't managed to get a good picture with good color, but this liquid is as pink as new coolant, and since there's a lot of oil inside too, the difference can be easy to see..

I fount the leak... It was charge cooler...

Coolant pump is changed this year, coolan expansion tank and cap are changed too, it's doing the same thing with the old ones and the new ones too. I've seen that there are numberous one-way valves on some of the tubes, does anyone know how many are there exaclty? How do you think egr leaking oil? There aren't oil lines connected to egr, are there?

I will try to take off o2 sensor on ionisator, to see if there is some kind of liquidation

I have red coolant

Hey, I didn't managed to bypass cooling for egr cooler, but, I managed to use endoscopic camera, and this is what I managed to see in the area of solenoid valve for egr. Is this maybe proof that egr cooler is broken/leaking?

Question, does anyone know what is diameter of tubes for egr cooler, so when I start doing bypass proces, I come well prepaired?

I'll try to test that. So, to clarify, is it even possible to get a crack in head on cr engines? Just to make me calmer, you know..

Well, it shoudn't be so heavy to do this, I just have to get under the car and sort it out. Do you think it could be cracked?

Waterpump changed in August, it failed, so we've put the one without that sleeve, header tank and its lid was also changed also with g13 coolant a few days ago. Yes, Wino, there is a small pressure and coolant then rises a bit.

Anyone?

Hi there I have a problem with my 2014 2.0 TDI with coolant, from time to time, once a month at starters ( I have it a year and a half for now) I had to top up coolant, OK, cap off, pour in some g13 and it's ok for a month. But it startet "loosing" coolant more frequently, and I came to a point where I made 40 km, and coolant went from above max to below min, just enough to activate dash warning. I've read sooo many topics about heater matrix problem, so, I went to shop and bought myself heater matrix, 5L of coolant concentrate, expansion tank and a lid for it. Just to say, coolant wasn't changed from 2014, so it was original coolant in there. I've flushed the system, also run presurised tap water for pressurised cleaning, then with deionised water, changed tank and a lid. I didn't change heater matrix, because it wasn't clogged at all, heating is great, tried cleaning it with hose water, it was all good. (and I also bought the wrong one, but, that doesn't matter now, because my heater worked before too) Now, I would like to know, what is capacity of coolant system, I poured in almost 7 liters of coolant. Second thing, I've noticed that coolant went down again, ok, maybe there is an air lock, but when the car was cold, I openned the lid, and coolant returned to a half of min/max mark. Today I openned the hood, when I got to work, coolant was little below minimum, so I left it to cool down, and when it was cool, I openned the lid and level rose above max mark for a 5 mm. Did any of you have such problem? Because Google is not very helpful friend in this situation Just to notify, HG is ok, we've already checked that. Some mechanics said to me that it could be head crack, so when the engine is cold, everything is ok, but when it gets warm, alluminium gets wider, and crack lets coolant to intake or exhaust valve. Car starts great, goes even better, oil is clean, there is no visible leaks, no loss of power, it hasn't any other flaws other than this loosing and regaining coolant. Thanks in advance ;)
