@@jamesslater9972 Hi James, I had a lot of white smoke coming out the tail pipe of my 1.9 TDI. So after finding this video, and using this process for diagnosis, i replaced the EGR cooler with a cheap (ish) one from eBay, white smoke gone! Two weeks later the EGR valve died too, which caused a huge loss of power. Replaced EGR valve all has been well so far!
If i have bad EGR cooler, my heat (hot air) will not work? I have this symptoms: white smoke, losing coolant, bubbles in coolant, coolant in EGR valve. But i have no temperature engine more than 90°C, no mix oil and coolant, no losing power on engine. So, there is 3 option: bad EGR cooler, bad head gasket or cracked head. What you think?
In general yes. But the smaller the leak the less of an issue. But it has to get fixed at some point. And the leak will most likely get worse, or have a total failure and then you are putting a lot of water into the engine. Thats bad. You need to note your miles and then how long it takes for the Low Coolant light to come on. That gives you an idea of how bad the leak is. I am getting water in the intercooler pipe right behind the EGR system, and I just discovered that. I thought I had a radiator leak. Now I think the EGR value is only open at start up. So that may mitigate the issue to some extent. But if leaking then you have to keep spending money on coolant, or put straight water in , which is not good over the long term and then when it gets cold you will need to put coolant in to stop the radiator system from freezing. Summary, its got to get fixed.
Thanks, helped me sort out my Audi A4 after the garage had passed it off as a head gasket issue.

Would a bad EGR Cooler cause antifreeze to mix with the oil and give you a oil warning light?
No

Bad egr cooler. That can push air into coolant and air lock the heater core
@@benturner4774 head was craked, i put new and now again missing antifreez. What can be problem now?
@@profpetarsazdovdo you know how it cracked?
@@AA-by7xc i sell that car. 8V engines are better
Hey, do you fix this?
Yes there's a video how I put the new one on..
@@AndersonERockefeller is it bad to drive like this? :D
