Today all of a sudden the exhaust started smoking white really bad from burning coolant. Has anyone had any issues with their TDI burning coolant? Where should I start... Turbo... EGR? It has been deleted from the CAT back. Thanks for the help.

I agree with you in many points of this post.
I myself am a trained Electronic/Mechanical Technician with ~38 yrs experience, 25 of those in Industrial Machinery.
Surely you as a professional must be curious if the Op's coolant level has in fact dropped as this is an important piece of information to help diagnose if coolant burning is what is causing the white smoke.
I rest my case....
I love it when people start throwing around designations on a car forum.....
Out of curiosity, how does anyone on here know if I am (or anyone else is) a garbage collector, a bum, a doctor, a plumber, a tech, a professional whatever, or work at the local weed shop?
STFU and provide solutions and data to sustain your statements if they are correct or even incorrect.... and if you say stupid crap, especially after throwing some title around, own up to it! (you know who you are)
How can a Professional Mech Eng jump to the conclusion of a HG based on what has been disclosed? You want this poor dude to tear apart his engine based on your professional diagnosys? How many HG failures have you seen on these engines? You should be ashamed of making such a suggestion on a public forum, especially after throwing your title around!
Is that how you operate in your Eng domain? When something fails, you just jump to a conclusion instead of doing any root cause analysis or any other type of investigation?
🤬 RAGE

@FlyingFin.
driving off road is far different than driving on pavement. During off roading the terrain can lead to several varied issues that are less likely to occur on pavement - the engine working harder to climb a rutted rockey stretch or deep sand IS NOT causing the engine to run the same as it would on pavement. Debris and rocks hitting the under side of the vehicle in amounts far greater than on pavement too. shake of vehicle off road never happens on pavement either.
So asking about the moments the white smoke began IS providing insights.
asking why the OP is going to start Parts R&R without a confirmed diagnosis is meant to help the OP realize he/she needs proper diagnosis BEFORE hand.
given the brief info the OP shared, its a free for all game because proper repair is not happening without proper diagnosis.
is white smoke coolant? Is it actually coming from tailpipe or just from under vehicle.
is coolant level low? Is there a leak from hose or hose fitting? Head gaskets? Is there coolant in oil or oil in coolant? Has a VCSD scan been done? What was engine temp when white smoke began? Etc.
In my opinion, the Advanced Search feature on this forum can and does assist in diagnosing or even finding how to repair specific issues. Someone suggested that to the OP too.
IF you think you can help the OP, you could use the forum PM feature to do so without your unwarranted apologies on behalf of other members AND your childlike name calling insults OR you could just post your idea of helpfulness for the OP.

Thanks Flying Fin,
For everyone that is interested, yes it was burning a bit of coolant as of the last few days, my wife only noticed the white smoking as she parked up at home. It was smoking like a hot rodded vape. The white smoke was definitely coolant. I took a VCDS scan but there was nothing of interest. The coolant tank was not pressurizing so I ruled out head gasket. I am a Canadian currently living in Mexico and getting anything like parts/tools etc is a gong show so I do not have access to a coolant exhaust tester.
A few years back I installed a Rawtech CAT back and Malone tune. At the time I was unaware of the downpipe CAT delete or EGR and cooler delete so I left it. I had the time today to pull stuff apart (all day in 35C heat... FML) as I am going to buy the Darkside downpipe and do an EGR delete. When I pulled the upstream AUX cooler it had lots of coolant in the exhaust plumbing so that is where I have my crack and coolant ingress to the exhaust.
Going to order a swirl flap kit delete with the EGR/Cooler delete and the downpipe CAT. Anything else you have done that you recommend?
Thanks again,

For those that are dickheads to other people, life is way to short. Help each other learn and don't belittle them. You're only as smart as you were yesterday...

Sorry for your rage... I clarified a bunch of info tonight. On original post I was a bit lazy because I was using my phone.
Thanks Flying Fin,
Glad you found the source of ingress of coolant into the exhaust.
Let us know if your burning coolant situation is resolved once the project is completed.
As far as the dickheads, I don't think they can help themselves as it's probably taught (you know who you are).

You need to take more water with it!!
What is the most common cause of steam coming from the exhaust smelling of coolant? Head gasket!!
How do you check for head gasket failure?? Pressure test the coolant system and do a sniff test which when added to the coolant in the header tank, will change colour if it detects burnt fuel in the system. Thats the easiest and cheapest place to start! Everything else will be more expensive, often resulting in changing parts for changes sake! You still call that jumping to conclusions?
The pressure test can be used for other coolant loss situations, but again, that would only be jumping to conclusions wouldn't it...
The idea of doing a VCDS check to detect coolant in the exhaust and 'driving off road will cause steam to come out of the exhaust' is laughable... If you don't have anything sensible to say, why say anything at all. You are not assisting, only helping to make yourself to look a little silly!

This sort of rant only goes to assist in proving your immaturity and lack of basic mechanical knowledge, and shows your jealousy in being unable to assist convincingly, probably down to your lack of education.
Basically if you knew what you were talking about, you would have thought, 'Oh yeah, I didn't think of that', instead!
Your idiocy really shines through when you completely dismiss the easiest test to make to rule out the most expensive and time consuming possible cause.
People like you don't belong on any forum where expert knowledge is required, unless Lego have a mechanical forum for experts like you that you could join...
I'm sure when you get to year eleven, your English will improve!
Unless the alcohol has already addled your brain!
TTFN... 😁😁
Children, you are free to play and make as many silly comments as you wish... Some of us grownups have adult things to do...
