DIY: Ultimate SAI/N249/PCV/EVAP Delete

[nstevic01]

I spent a lot of time on this, I hope it will be helpful. This is the guide I put together to be used in conjunction with a kit I put together. I did the install on both a AWP and AWD motor. There are slight variations in the vac lines, but the instructions indicate which motor is in the picture. If I am missing anything, please let me know.

Engine codes this write up has worked on (if you have a engine not listed and this has worked for you, let me know and I will add it to the list:

AWP
AWD
AUQ
AWW
AWM


I will make you a kit if you are interested. PM me for details.

For those who want to piece the kit together, here is what I used:

- Integrated Engineering Block Plate
- 4 10w 330OHM Resistors
- 8 feet of 3/4" Hose
- 4 feet of 1/2" Hose
- 4 feet of 5/32" vac line
- 2 3/4" 90 degree PCV Elbows
- 1 3/4" PCV "T"
- 12 Medium Hose Clamps
- 6 Small Hose Clamps
- 1 Pack of Assorted Small Vacuum Caps
- 1 Pack of Large Assorted Vacuum Caps
- 1 Homebrew Catch Can
- G12 Coolant


Optional (While your in there) Parts:

- Coolant neck: Automatic Transmissions: 06A 121 133 AH Manual Transmissions: 06A 121 132 AP
- Newsouth Performance Power Gasket, or stock intake manifold gasket
*Now is also a REALLY good time to install a oil pressure sender using the port on top of the filter housing to use an aftermarket gauge.


Tools Needed:

- Gloves
- Flathead Screwdriver
- Set of allen wrenches, or allen bits for your socket wrench (5mm, 5.5mm, 8mm, some other may be needed)
- Socket Set (8mm, 10mm, some others may be needed)
- Cutters
- Soldering Iron
- Solder
- Electrical Tape
- Zip Ties
- Jack and a Jack Stand (to be safe)

**Disclaimer** - I am not responsible for any damage done to the vehicle or yourself by performing this modification. I am simply collecting all the items needed and providing them to you as a convenience. Most states require the emissions systems on your vehicle and removing them could cause your car to violate your state's emissions laws. That being said:

GOOD LUCK!!

Well done!

Well done!

Thanks! Took forever, but it feels good to have it done.

Very impressive!

[sounrealx]

"ultimate" delete is right. Good job!

how is readiness handled with these modifications? I need to pass inspection in NYS.

Without proper programming, you most likely wont be able to pass. I'm not sure which of the ECU programmers offer that.

Can I remove the blue balls without any reprocussion? I'm been trying to remove useless junk in my engine bay and i already have capped off the one on the valve cover. (Doing this without removing evap)

The blue balls are hidden and weigh nothing. IIRC they are required for the EVAP to function properly and not throw codes (since you want to keep the EVAP). You really would only want to remove them if you were doing this entire delete.

[RobClubley]

Awesome guide! Thanks for taking the time to create it.

[waabaah]

bump for later reference

[hootyburra]

Add this to the faq, along with sav's diy even a moron should be able to complete this.

You should add a not to stick some paper towels in the intake ports so you don't accidentally drop anything down into your engine

[turbo2205]

awesome write-up; clears up alot of the ?s ppl had with the other write-ups. this needs to be stickied. and PLS try to keep your pics hosted so they dont disappear from this write-up, since it's pic-based.

well done x12 for u.

for a programmer that cancels the emissions CELs, eurodyne maestro you can delete them yourself so they never pop up again, and I know APR will do it if your Stage 3+ but thats it.

If anyone finds a tuner that will do it for them let us know!


Amazing DIY.

Eurodyne Maestro 7 is $899.99 Although for what you can do with it, it seems worth it.

[Tacosupreme]

Very good write up

Worth every dime.. Even on a stock turbo setup

Is it safe to remove the pcv valve?

[nstevic01]

If you are talking about this piece, it stays. Only other "stock" piece that remains is the Brake booster check valve.

[Henni]

Great write up!

[ParanoidPJK]

Words cannot describe..
Best DIY, ever?

Thank you so much for putting down the effort to get this done and help others. If I do this sometime soon, I'm going to pay you for the kit (which I assume is slightly marked up?) to reward you.

One thing though, I was hoping there would be some kind of panoramic shot of the engine bay from above to show the difference in the completed product.

[lamarvannoy]

mad nice. good write up. what codes am i going to get for this? will improper flow dick with my CEL?

[talx]

Good write up …… but change that valve cover gasket it’s a strait forward and simple job

Yes the kits are slightly marked up, but not by a whole lot. I have 2 left of the first batch and may do more if people want them. I will get the shot for you this weekend.

Depends, if you dont have software to delete the CAT, you will prob get one for that, and you may or may not get the one for improper flow for the EVAP flow regulator.

Already changed, my car is the one with the blue TIP

Excellent! Yeah, if you find yourself bored and with a camera I'd love to see the shot sometime. Thanks again for the thorough, idiot proof write-up.

[sounrealx]

Here's a pic of my car (the one with the red tip from the diy) sorry my phone doesn't take great pictures.. and btw my VC gasket had been replaced a few times, i just have a dirty engine.

[nstevic01]

And here is mine, the other car from the DIY

[sounrealx]

way to 1-up me with your super camera

[ParanoidPJK]

Thanks for the pics! Is the engine noticeably free-er to work in? Im doing some turbo work and nothing pisses me off more so than these stupid vacuum lines (mainly the ones on the drivers side of the block that you have to snake the oil feed line around)

Honestly, working in the bay has become noticeably easier. Things are alot easier to get to, and leasks are easier to pinpoint.

Great writeup, but that rusty brown looking coolant coming out in some of the pics doesn't look so good.

Yeah, that wasn't my car though. The car had a auto to manual tranny swap and the guy who did it capped off the hardline to coolant neck ports, so im not sure if that led to the nastyness. I fixed that for him when we did the install, you can see the handywork of elbows, clamps, and small hose bits.

[Budsdubbin]

How did you get the 3/4 heater hose over the valve cover pcv outlet. I tryed heating it up/lube it just won't go.

[surfinsk8r]

That was probably the best DIY I've seen to date. My only question is, does it directly apply to an 2002 Audi TT 225Q? I believe it has a different engine code even though it is very similar.
What would be different?
Thanks!

It goes on, you just gotta work it. Out of the 2 I have done, it really only took me a couple of seconds to pop it on. Perhaps you broke off the reducer/checkvalve like I did in the pic with it wrapped in electrical tape?
