Hi all, new here.
Here is the new to me Touareg 2014 TDI Execline with R line. Car is in very good condition and was completely stock when I got it. I live in Montreal

rear seats when I got it, now has 3 kid seats and monster mats.

First thing I did is to remove the original “fabric” mats with OEM monster mats front, rear and trunk.
Second thing was a Malone Stage 2 tune (keeping emission stuff). Next was the Start & stop button renewal, and when looking on how to do it I found the auto-hold function; so I just ordered the button.
I see some rockchip on the rocker, so I got mudgards for all 4 corners. Not sure yet if I will install the rear one as they are quite big and do not protect anything.

Coming next
H & R springs
20in wheels, maybe 15mm spacers. I don't think I would go over 20 as I like the tire sidewall on such vehicle.
Disable video in motion for the entertainment of the 3 kids on the back seat on longer haul
Gear display

I would like more power, but I don’t think the investment would be wise for the power gain (new turbo). I would like more compression braking, so most likely transmission tune eventually.

You misunderstood my question.
You should log\plot your current performance on a compressor map for example so that you can determine if increasing the cold side is what's really needed. Since you already have @Brendanm on the other side of the pond already running the turbo upgrade you're going to, why not do logs to compare with him? That should easily tell a story of how these two setups differ.

Let's assume that your compressor CFM is your limiting factor @ 4k rpm. Will you have sufficient fuel to support more air? Will your intercoolers be adequate for more boost? Are you going for more boost and flow or just more flow at the same PR?

Unless you have some data points from your current OEMish setup, you're just making assumptions. What if EGTs are you limiting factor at the moment?

You're already chipped and stuff so it might be worth trying to figure out where you are on your current compressor map. Attaching a random map I just generating for visual purposes

I think you are overthinking this. This is a small upgrade, not a GTD2872,

EGT are definitely not a deal breaker at the moment, I know Malone still use a limit. forgot the number, but well known it is not a issue here. EGT will be almost completely out of the equation with the deletes.

Intercoolers, not an issue either considering the use and climate. If this would be a A4 track car, different story. There are no off the shelf alternative anyway; unless a FMIC which I am not interested in. Again, not a GTD2872...

I believe the turbine will make some difference, so if I can extract more from the exhaust I can get more CFM on a broad RPM range, not just over 4k. I understand that you need power in the engine to get power in the exhaust; but I also expect a gain as soon as the turbo spools.

Dyno chart should shift a bit to the right (lag), and shift up (more power). I believe the better turbo upgrade would have been a GTD2263 and meet my 350HP ish goal But If I compare the upgraded wheels I posted above, this should be close. Since the GTD is not a plug and play, I like the idea of the GTB2260 core.

Happy holidays to all forum member!
more parts are in

Not even install and I feel the truck feels stronger. haha Cannot wait to install this and the new turbo.

still debating if I am rebuilding/upgrading the turbo or if I install it as is.

I mounted my winter tires on the OEM wheels, I'll use theses for summer.

TCU flash this afternoon to pre-emission fix, looking forward for that.

I'll do the log soon. Flash is done, but didn't the chance to drive it enough (flash done when engine was warm). I don't expect a lot of changes on a warm engine anyway, maybe just a bit more compression braking.

The only reason I did the flash is the cold engine "high" rev ****, near 3k RPM on a cold engine is not a good feeling. Not worried about engine durability I as drive very gently on a cold engine, just really annoying.

Did the flash, engine crank but won't start. ****. Key was in the "ignition" and I guess I pushed the start button instead of turning the key. Tried again and it worked. fioouuuu

Then, auto-hold button didn't work. Shut down the engine, wait 10sec. Started like a charm, everything back to normal. Transmission was still in Cayenne mode, gear display active and all.

thanks @KatanoTDI for the job.

Drove the car for the first time when it was cold, I am VERY pleased to see that the high rev behavior is gone. Shift around 2k RPM on light throttle with cold engine instead of 2500-2800. Did not noticed other significant differences from the short drive.

I didn't pay enough attention on the 1-2 shift delay, I'll check later today. It was definitely present/annoying when using the shift paddle, there is almost a 1sec lag between the moment when you hit the paddle and the transmission shift. This was quite a contrast when comparing the DSG transmission from a Golf Alltrack. I have no other complain about the AISIN transmission.

I intend to do a log, but I am not sure when as my commute to get the kids only involves city driving (no highway). I am not sure with the cold like today (-11C) that the engine will reach operating temperature when I arrive at daycare! I'll have to keep an eye on the battery charge...

Not an exciting update
started the car, everything is fine. Put to drive and I get a rear adaptive fog fault. Weird. Stop to pick one kid, start the car front adaptive (fog or headlamp, forgot) fault when I put to drive. argggg

This was one of my concern buying a Touareg, filled with sensor so many things can go wrong. I'll plug VCDS when I get the chance and look into the problem.

It is quite cold today (-18C), maybe related. hopefully I won't get to many issues like that and it can be solved easily. Since there seems to be an issue at front and back, most likely a connector or module that is acting up.

Have you played with lighting at all in vagcom?

wierd issue, intermittent.

One of the front fog is not working. When I got the car, I had a spare one that has been just replaced; it didn't appears to be broken. I suspect something wrong with a connector/wire/module. The front fog fault happens when I turn the fog on only; and at the same time I get a notification that I have front adaptive headlight issue. I just started the car and they move up, then inward then outward.

So you have a dead fog?

The headlights are supposed to zero out every time they're turned on, have you never noticed??

You can't turn fogs on without headlights

Yes one dead fog, which is pretty banal I know. But both fogs are 3 months old so it is quite annoying.

I noticed that the headlamps are moving when I put the car to D and they still do.
What I don't get is why I get an adaptive headlight fault when I still see them moving correctly; and the headlamp fault happens ONLY when I manually turn on the fogs. I typically never touch anything in regard to lights; set them in auto and forget them. They must be on the same circuit and one controller get a different voltage... but I would have expected than a fog issue wouldn't trouble the headlight!?

You can change your coding to use the fogs as DRLs which would do exactly what you're saying is impossible.

Wait, so even AFTER the he headlights do their initial zeroing when first turned on, they continue to move while driving? But this only happens after turning on fogs?

Indeed, but OP already stated he didn't mess with lighting coding in vagcom.

No the headlamps only move on startup (at least enough that I can see, I am sure there are more subtle movement when I drive).
The headlamp seems to work properly, but I get an adaptive headlight fault after I turn on the fog AND a defective fog fault.
