Doing the same here, the sale is too good to pass up. I also time out in October but I am a lot closer on mileage so we shall see.

 

Are you going with a Stage 2? For the money from TZ, you might as well. I was thinking of the Eco from Rawtek since the Treg does what I need with the current power level. Not sure why I decided to check TZ directly but I'm glad I did. Under $800 for the Stage 2 tune for me.

 

So you're only deleting DPF? Or flaps, EGR, DPF, cat, etc?

 

Great question. Important to capture all the above except the cat to keep stink and smoke down, assuming you're willing to replace the cat every so often

I'm deleting DPF/AdBlue, NOx filter after DPF, and EGR. I'm debating about the swirl flaps. EGR will definitely be coded out and removed at some point. The downpipe will remain in place with the first cat.

Swirl flaps WILL fail. It's a matter of when. The EGR physically in place WILL cause issues, even catastrophically

New here and to this topic, could someone please explain how it's possible to do deletes without repercussions in the US? Is there no Diesel smog test in some states? I'm in CA, which I assume precludes any of those extra fun factor things... TIA.

Nope you're hosed

Not everyone can find "value" in spending $3k on deletes\tunes if the current hardware is fully functioning.
It takes a lot of driving to get ROI on that sort of "upgrade".....

Agree. I've left every emissions system intact, but once the warranty is up, I buy the parts and keep them on hand for the first time I pop cel for them, then they're gone. It's just too risky keeping them around, knowing they WILL break again, and again, and again.

 

Going with Stage 2 and deleting all the things except the cat. Did not see the EGR delete as an option but I am sure I can add that in. As far as EGR delete hardware is concerned I may need a bit of direction...

I noticed on one of my customers CATA engined Treg that even though the dual intake flaps were coded out they still operated until you physically unplugged them. I believe his was a stage 2.

I also kept my DOC downpipe standard, it really brings the diesel smell down after a minute or two. Also apart from when your going full tilt, you won't notice anything smell or smoke wise which gives you a bit more stealth in your delete. Cops are really starting to crack down on smoking diesels

yeah you can’t bc CA. But others can, bc ~not~ CA lol. I’m in PA - there is no emissions testing for diesels.

 

Yeah, there are a few states left that don't do emissions testing.

 

Can also confirm we don't test diesels in texas just safety inspection. Take into account carb emission standards are the strictest in the country and most other states that are strict adhere closely to what they do. Even OE manufactures bend the knee to them.

 

Thanks guys, it's what I thought. Lucky you.

Since we're on topic, has anyone here done the Malone/Tunezilla TCU tune and found it worth it?

It looks sensible in combination with a stage 2, as the transmission was also modified after Dieselgate, but the price is just too rich for my blood at the moment.

Or does someone know how to do the mentioned 'pre-diesel gate reflash' by other means?

Malone/Tunezilla tdi TCU tune review

This is a review on my opinion of the Malone/Tunezilla TCU tune for the aisin 1000 8 speed trans in the 3.0 tdi vehicles. Im writing this review as I noticed there is NO reviews for this tune that I could find. I purchased this tune on Tunezillas 15%off spring sale. I went for the tool rental...

Interested transmission flash fix people please step...

OK so I've compiled together a list of all the possible TCM's that I have found: If anyone has one that is different please post it here along with the year. I am also going to list the ones that I can currently flash, and the ones that I need donors for. Thanks everyone! 0C8927750G Can flash...

The pre dieselgate transmission flash makes a decent difference, to me it seemed to rid some of the delayed response and hold gears a little longer in sport mode.

Supposedly tunezilla took it a step further, I know a couple of stage 2 cayennes on rennlist installed it and after some revisions really enjoy it.

 

I have the TCU flash from tunezilla. It's okay.
I wouldn't say it left me impressed that's for sure. I have stage 2 so maybe it overshadowed the upgrade. Does engage firmer and quicker for sure so there's no longer bigggggggg delay between shifts. However A DSG flash is night and day difference in comparison but we're comparing apples to sausages.

 

I would also venture that the factory programming on a Touareg TDI Aisin is better tn an the factory programming on a DSG car. I’ve owned severalDSGs. They are my favorite transmissions, but they are horrendously tuned in all applications until you get a TCU.

Dl800 is in the audi R8/lambo transmission. It's a seven speed dual clutch. I highly doubt it would bolt up to a touareg unless you really really wanted a MR drive touareg and a blank cheque.

 

MR drive? Everything on google is just douche bags and their crappy car blogs “Mr Drive”

manual rear drive?

 

LMAO

Go play GT and learn about cars!

 

Thanks for the heads up. I am going purchase the stage 2. And then the rawtech delete pipes. But I saw they have the full exhaust on sale but I’m concerned it will smoke too much or could cause drone in the cabin. ????

 

With a cat delete, dpf delete and muffler delete, it will be loud no doubt. Thankfully MOST of the noise will be out of the rear of the car though

 

On a somewhat related note, does anyone know what the potential lifespan of the 3L DOC is?
I can only suspect that due to the increased emissions resulting from the tunes, their lifespan would be shortened.

 

The first cat after the turbo, in the downpipe, is what we are referring to as the DOC, correct? Why would it matter if the stuff after it is there or not? The EGR is the only thing I could see affecting it, but even then, not really. It's not like the treated gasses go back to the turbo to be sent back through the DOC and they are now cleaner and "easier to digest". Does a tune really let the engine emit more nasties? Other than the EGR not being functional, I don't see how it would amount to much more. A little extra fuel here or there, sure, but you're not "rolling coal" constantly.

If I'm misunderstanding the system, please enlighten me. First-time diesel owner here, but I do understand automobiles in general.

 

Yes, that's the DOC (cat) we are talking about.
It gets "raw" exhaust... so all soot, particulates, oil, blow-by, fuel, etc.... everything that results from the combustion.
As power goes up, more emissions of all those things will result.
So it will be processing that much more stuff\flow\volume, and since it relies just on internal materials\coatings to perform the reaction, it had a finite lifespan.

What is or isn't down stream of it won't matter for this "discussion".

Think of a typical cat on a gasser.... it needs replacing at 200k or whatever... same idea

 

DOCs are designed to last nearly as long as the vehicle. Lots of tdis driving around on their originals, 4 and 6 cylinders. Some over 600k
Unless they get 'poisoned' or clogged they are a passive emissions control which doesn't really 'wear out'. I've seen the ceramic break but that's from outside damage like exhaust hitting a curb etc.

Deleting DPF allows way more PM2.5 which can damage lungs in large concentration, isn't an issue if your highway driving. The NOx and its various counterparts are also pretty bad in large concentrations when you delete the SCR system.

 

DOCs are designed to last nearly as long as the vehicle.

Agree, however, both fuel & oil are contaminants that cause the DOC to experience way higher temps..... not to mention that the new increased\sustained +100°C EGTeeezzzz limits add that much more heat to the "system"......

We have seen\heard of VW replacing OEM DOCs on dieselgate vehicles, so they definitely aren't lifetime in the application discussed here.

 

High temps and contaminants chip/erode away the ceramic bit by bit.
A car that uses a DPF and requires an active regen requires fuel to hit the DOC to create the high temperatures required to get dpf to burn off

If you have deleted you won't be seeing those conditions nowhere near as often as the only time you will get excess fuel is on hard acceleration.

This is why I can't follow what you guys are saying.... I'm still stock.... all you guys doing Stage 2+ tunes must be staying off the go pedal more than me!

 

Ya, it is not cheap. Worse for me as it was $1342 CDN after the exchange rate, taxes, and shipping.

 

Damn, that's right at $1,000 US! Mine was $846 US with shipping.

 

I'll lean into it a few times when I first get it done I'm sure, but I don't floor it often now. Being one of the poors with a $60K luxury German SUV, I have to save money for high dollar repairs and high diesel prices.

I'm not getting a stage 2 tune because I need more power (cue Tim Taylor) but because I want to delete and I need a tune to delete. I almost went with a stock/eco tune but the price difference was such that I went ahead with the stage 2. I don't plan on driving in S (I don't now, and that would be the poor man's tune simulator for me at the moment), nor do I plan to drive like my wife - foot to floor with whichever pedal her foot is on (I call her a digital driver, like most women, ON or OFF) - so it really won't matter that I have a stage 2 tune. I want more reliability due to the high dollar replacement parts being gone, and potentially better fuel economy. The added HP and torque will be a bonus. I may not be the norm, but that's how I drive now and plan to drive after the tune.

You and I are in the same boat lololol. I usually mod the hell out of my cars but I’ve been resisting to keep money saved for maint and repairs for the T.

Though diesel has become reasonable again. I pay less tha $4… I’m happy.

 

@C-ya
I'd suggest some research into the tune you're getting in that case.
If power is going up, emissions will too. I believe I've already made some reference to the rich conditions that are used to increase TQ delivery and spool in prior discussions on the lambda values.

 

And for fun, here's how they fluctuate due to all those things, throughout all the readings I've taken over the last year during my routine scans\maintenance\PM\whatever that I've saved. So this covers all my use.... summer, winter, daily, towing, whatever.....

I also agree the NOx is way worse. But our tdis are just a drop in the ocean.
Not going to turn this into an emissions debate but I found amount of NOx a single container ship generates running bunker fuel in one day is equally to every single VW tdi in North America running in cheat mode in a average year. It's crazy. And do you realize how many ships come I to docks in North America in an average day?
And then there's air travel....and gas heating systems.....off-road equipment.....trains.....

I believe dieselgate was political as well as sending a message to the rest of auto manufacturers that they are being watched.

okay… this does make me feel better, and I have also considered this. I mean **** - did my diesel school bus have a DPF, EGR, and SCR??? I was around those things pretty constantly till high school… as I imagine most public school educated people are.
