Just my 2 cents here. But I would think its' not a big deal. IE if it gets gunked up. Get to it, take it off, spray it out with carb cleaner or etc... and re-install....

Here is the video from An a4 B7 TDI. Its' function looks very similar to a standard throttle body... might be a PIA but atleast it would likely be an easy enough fix. I know this is not the exact same motor, just shows that it can be done if necessary.

Appreciate your input? Did you put a link to the video?

Well its gotten quite brisk in Chicago. I was a bit worried about warm up times after the delete.

When leaving home or somewhere close to a main street of 35 to 45 mph speeds. Car is warmed up and producing cabin heat in 2 to 3 minutes.

Leaving work, its a lot of 30 mph with constant stop and go from lights till I hit main streets. This driving has a noticeably greater affect on keeping the car from warming up quickly. Until the car gets a consistent minute at 35 mph it doesn't want to get warm nearly as quickly from a complete cold start.

Great thread, exactly what I've been looking for.

I have a 2014 A7 TDI and have been debating a tune for a long time mostly to get rid of the turbo lag in traffic. My original thinking was to go with a Malone stage 1, but it seems for best results to eliminate lag I should be doing deletes + Malone Stage 2, basically what was done with this A6.

There are 2 DPF delete kits, BuzzKen $900 or DarkSide Developments for $450
EGR Delete plate $30 from DarkSide Developments
Malone Stage 2 - $650
Flashzilla - $180

Items to consider, swirl flap delete? Is this necessary?

The only reliability issue I've read about doing deletes is that by removing back pressure the turbo spins faster, therefore it wears out faster. I am new to diesels/turbos, internet seems to be all over the place on this.

Big concern is black smoke, looks like it shouldn't generate much soot, but can't find good enough reference videos.

Diesel smell in cabin is the other issue, it seems reviews for most malone tunes state that there is a bit of an increase in smell.

Hey there, glad my blog is helping. I'll see if I can answer some questions.

Turbo Reliability - We delete to help the turbo. I believe heat is more detrimental then spool speed. The tune should keep the spin rate at a safe level to not put added stress on the turbo. Speaking from my 1st tune before deleting to the 2nd tune after deleting. The EGT reached alarming temps with the DPF intact with a minuscule 25 extra hp. The 2nd tune after the DPF delete, the car handled an extra 55+ hp and 75+ trq while keeping EGT temps at the level of the stock car. We could of pushed it more but I wanted to stay conservative. I love that the temps are lower with the extra power.

Black smoke - At first there was an alarming amount of thick black smoke. Within a few weeks of driving that eased up to the point I only see a cloud on WOT redline runs. If I try to make a quick lane change and give a little extra (not WOT) I might get a slight puff.
+FYI - I'm using ULSD #2 Diesel in my car. This produces more smoke then Biodiesel. I have added Standadyne Performance Formula 8 oz every other fill up and noticed a considerable reduction especially on the lane change type moves. Prior to it, the smoke would of been more noticeable. Not sure what you'll be using.

Diesel Smell in Cabin - Rarely is this noticeable and it is only when the windows are open and the wind is blowing in a specific direction or no wind at all and I'm sitting at a light. Again this is only with windows open. A quick remedy, throw the recirculating air, AC, or heat on, and the smell is gone. I do not get any smell with windows closed. If you are getting it in the cabin, something is not tightened up properly and allowing exhaust into the engine bay then into the car.

Swirl Flap Delete / EGR -
https://www.clubtouareg.com/threads/t3-tdi-intake-swirl-flap-delete.288285/

Only thing I could really find. A lot depends on your car. For my A6, there isn't a block off plate to purchase. The EGR is tuned out and stuck shut after speaking to the shop, Buzzken, and Rawtek. The swirl flap is another non-necessary delete from reading around. I'll add, my car has a setting to create heat for the car using the diesel. Its in my MMI settings. I've switched it on. I can now get heat fairly quickly from a cold start by setting heat to High, 12 for power, and recirculating. I can even warm the car up in the driveway now which I thought was going to be useless after the delete and the car not moving.

Awesome, thank you so much. You have literally answered everything I've been scratching my head at for a few months.

I am based in Canada, I am told our Diesel here is different than the US, I am not sure if it's for the better or worse.

You don't happen to have any videos of your car's rear at WOT would you? There are a couple of youtube vids of Q5's and Q7's with the same mods and a malone stage 2, but it's all bumper mounted cameras that don't provide context to how much smoke is actually behind the car.

The big decision I need to make now is whether to void the dieselgate extended warranty that I have up to 120k miles. Currently at 96k.

I can get a video made. Might take a few days. Weather is about to be horrendous in Chicago and very busy with work, a newborn, and Thanksgiving week.

I was asking myself the same question about the warranty. I decided that I wanted the car to be setup the best way possible for power, longevity, and least amount of headaches with keeping in mind I would be footing the bill moving forward.

If you can afford the possible problems (there should be less) I don't see a reason to not make the car what you want.

After extensive reading, more often then not problems occur from the emissions equipment. That headache is now gone for me. I feel for the guys who hold the warranty and have to play phone tag to get their car worked on from Audi, who really doesn't want to waste their time on the problem anymore. Then their car sits in the shop or possibly another headache down the line. Not to mention there is a SECOND!!! Recall on the DPF for my car right now. Glad I'm not dealing with that when parts seem to be scarce. I know from my one stop to my local Audi they do not store TDI parts on hand anymore.

My investment should lead to better reliability all around while I get the fun, power, increased mpgs, no more turbo lag, a nice throaty sound as well. I can call my shop up in a moment's notice have the car to them that night and parts ready in the shop the next day. Again out of pocket cost but they aren't charging me Audi prices.

To me, not worth it, but I only had 32k miles picking this up as a one owner Audi lease. I hope sticking to the maintenance plan religiously will give the reliability weve had in our 09 Mercedes CDI.

My Q5 is deleted and straight piped and I also use Stanadyne Performance additive and it helped quite a bit. Works great for me! I’ll have my wife take a vid of my cars rear end while I’m driving off and I’ll post back here.

Have the date with Audi on the 26th to get the new DPF downpipe installed. I am planning on removing the secondary cat at the bottom of the downpipe shortly after. It’s not hooked up to anything O2 related so that’s nice.

Anyone else done this(remove second cat)?

Are you sure it is not hooked up? There is another sensor further down the line (post Ad Blue injection) that may be impacted.

I will do a triple check but I did not see any connection even near that second cat. It comes right off the downpipe and into that cat. I'll keep everyone posted here when I check again later today as well.

Side note, I'm not looking for some huge power bump but maybe a more free-flowing exhaust and less restriction while holding onto the alphabet soup.

Look further down the line under the car for the sensor. I am pretty sure you will need a delete tune if you remove anything upstream from that sensor.
I removed my mufflers, no noticeable difference in power and very little sound increase. I am tuned to ~300hp and 527ft-lbs.
There are little to no gains removing any exhaust components unless heavily modded.
You will be hard pressed to exceed 300hp with stock turbo.

Haven’t gotten back under the car yet. However, I did turn up my CW box to D-1 before I left work today. It’s similar to the C-1 setting but it definitely has that extra punch across the board. Keep y’all updated through the week/weekend as I drive with the new setting.

Update:

Still on D-1 setting. It definitely uses a bit more fuel and keeps the RPM's around 2K before shifting but it has smoothed out the car a lot in these winter temps. It pulls even harder across the range and I will be keeping it there.

Dropped off the A6(and our Q5) this morning to the Audi dealership for the new DPF/downpipe. They gave us some rentals and they gave my wife a brand new S-Line SQ5...I think im about to lose $60,000 lol

Car feels great after new DPF. Probably more from being a new downpipe altogether but super smooth with shifting and pickup. Highly recommend.

Someone a while back had asked to see how the exhaust looks on WOT. There are no turns or intersections the rest of the way down the street for safety purposes. Also, don't have a go pro to attach. Not sure if this gives the proper idea or not. Wish I had video of what this looked like when I first had it done. We are talking Dodge Cummins smoke which it is not anymore.
https://youtu.be/N89XnhX5gDk
Video/Sound inside cabin windows closed. Also took a video which is for sound purposes of what it sounds like at WOT with windows closed. You'll need headphones or speakers for it to have any revelance though. You can hear the change clink back when throttle is down :p

Android Auto has been uploaded into my original MMI system :)

Details and photos to come.....

Anyone who is looking to have Carplay or Android Auto in their car. Here is the guy to contact. There is no removing of the dash or installing of any new parts.
Contact him on....

The whole process took 45 minutes at most. The faster you click the faster it gets done. He will ask you to send photos as you complete each step.

Some thoughts, use a backup laptop or make a new profile on your PC for safety concerns. You will need a USB to Ethernet link, ethernet cord, an SD card, and download Teamviewer on your PC/MAC

After two weeks of use the $155 is well worth it with some small caveats.

-This is a wired connection. You will have to connect your phone to the usb port every time you get in the car.

-The android auto functionality is stuck to the normal app with safety in mind. I'm unable to play videos on my screen. Not needed for me but some might want this if they are spending the money. RS Nav or DMP Designs might be for you then...

-Spotify is fully functional now. When I was using Bluetooth MMI there was no way to search songs nor scroll playlists without touching my phone. Now I can do it with the scroll knob quickly and easily. All the info right on the MMI screen for easy viewing.

-Google Maps or 3D Google Earth if you prefer is very smooth. Seems unnecessary but I've found hidden gems all throughout the Chicagoland area with Google Earth running now. As I'm driving a shop or restaurant will pop up on google maps that you would have no idea is there otherwise. Best part is it is not using the Audi data/sim card.

-Texting is stuck to the Android Auto functionality, text to speech. Basically you won't be reading any text on your screen through android auto.....the basic MMI text message app works to read on the screen. I say this because I'm sure some might not want the texts read out loud for everyone in the car to hear.

-Waze works as well.
