Thank you for your reply.
I started having DPF issues mainly because I didn’t understand how to drive this type of vehicle and the regen process etc. so after doing a ton of research. I see it was best to get a tune and remove the DPF.

i did not have factory DPF on When I purchased the tune.
I physically removed the DPF. Then installed the tune.
Everything else was Left as stock. At that time I didn’t know about EGR block off plates.

everything worked great For 8 months.

Then i noticed the car was eating more oil than previously. No leaks anywhere. It wasn’t a lot, maybe a litre over 5000km

then about 3 months ago i fired up the car to goto work and white smoke billowed out the exhaust.
no coolant in the “V”
it was leaking from the aux cooler.

so I bought everything. new MAP, MAF, oil catch can, new PCV , CAT delete downpipe, swirlflap delete kit,EGR blocking plates and I think that is it.

First I cleaned out the ASV, plastic intake manifolds, all new gaskets , and physically removed both egr coolers and did a bypass.
While I was in there , I replaced the PCV , it just vents to a catch can and then to atmosphere.

then I installed both EGR blocking plates. Plus installed a new battery.

fired up the car and everything worked perfectly With the exception of limp mode on initial start. Shut car off and turn on again and everything works as
normal.

so then , after doing research, I replaced MAF and MAP. I did teat
like unplug the MAF and go for a drive and same with the MAP. No change so I replaced them.

i will upload a copy of my log after work. Thank you for your help.

Thanks for the clarification, but, Jesus 😳 are you just throwing parts without knowing what you're doing??

then 3 months ago I got white smoke billowing out the exhaust. I found that the aux upstream egr cooler was cracked.

the car , when started gets an overboost. And is in limp. No cel, nothing. Turn it off, and on again, she’s good to go.

#1) The rear egr coolers on CATA engines are a known problem, it's not a a question of if, it's a question of when. I've removed enough of them to hate them with a passion. They have probably killed more CATA engines than anything else combined. Reroute the coolant hoses and block off turbo port/intake . I just leave it them on the block.

#2) Contact Malone/tunezilla and start doing some logs. They will adjust that canned tune. Turning it on and off isn't fixing the problem, your just treating the symptoms.

I ended up speaking to a tuner friend in Europe (old buddy) and sent him the file on mine. He cleaned it up and after 2 logs my egg is running as it should be. Cost me more money but it was worth it.
Even my oil consumption has stopped which is really strange but I'm not complaining.
Now driven 3000 kms and level hasn't moved, before it was eating a litre every 1000 kms

yes.

after reading a lot of the forums I see that is probably not the best way to go.

after the dealership really messed me around I just decided to figure everything out myself

And yes, I feel very much, so in the dark when it comes to most of this and especially tuning.

But I really like my car and so I got the whole VCDS thing and we won’t talk about all the new tools that my wife doesn’t know about that I may or may not have bought.

I think I’ve done pretty well so far, honestly, I’m thinking that it’s either a tune or the anti-shutter valves or my turbo was just shot.

If it’s the turbo, I don’t know if I can rebuild it, but I’m going to try. I was just hoping that someone on these forums might point me in the right direction.

I’m just heading home now. I will post my scan soon as I have it.
Thank you for your time

excellent.
thank you.
yes I completely removed mine and made my own bypass to loop it.
everything is working really great so far.
im hoping this last issue will be fixed with the tune.

I also picked up a set of autometer gauges, a boost gauge and a pyrometer. Someone mentioned it’s good to have.
haven’t installed them yet but I know that you can read all the sensors off of the ECU , I was told it’s better to have some actual gauges too.

anyone have an opinion on gauges for a 2012 Touareg or just a waste of money?

[Reapertsm]

Yea I did contact tunezilla
im working on figuring out how to make the correct logs.
i didn’t realize the difference between “canned tune”
and more of a custom tune.
kinda getting it figured out now.

thanks for your help.

 

[Reapertsm]

Well it works!
tunezilla sent me the retune and everything is functioning perfectly.
To the person above who laughed at me for throwing parts at my car for no reason…. I have learned my lesson.

Thank You everyone for your help.

You cannot rebuild a Garrett variable geometry turbo for the record. Otherwise it seems like you're on the right path. If the car is still under warranty I think it was rather hasty to have deleted it

Elbows deep in tearing down a common rail diesel and not knowing the difference between a canned and custom time though 😳

Glad to hear a retune worked! 🥳

Yeah, well a guy has to start somewhere. 🙂

Car was off warranty long time ago.

latest update is the overboost problem has come back.

going for a more custom tune now and see how it goes.

thanks for the info on the turbo rebuild !
