Default Should I do egr delete? And or a tune

While I was doing my timing belt I noticed it was all black and gummy in there. The guy cleaned it right before I bought the car. I saw it was clean with my own eyes so this happened in about 5k miles. Is there a vcds setting I can mess with? Any positives or negatives to any of this? I donít really want to hurt mpg as itís the whole purpose for this car.

I was also thinking of getting a tune as from what I can tell on here Iíll get more power and fuel economy. I believe itís stock clutch so Iíd rather not have to replace that at this time. Any recommendations on that?

Stage 2 tune with EGR optimization helps warm up faster and decreases the amount the EGR functions limiting the gunk.

I'm in the delete camp. Tales of slow warmup are overblown in my experience.
Just make sure you've got a good thermostat and temp sensor.
A catch can is a big help to keeping the intake and turbo cleaner.
Stage 2 tune is all you need. IIRC you're in CT? Should be a Malone
dealer handy.

I also live in ct and deleted my egr in February. I saw no noticeable difference in warm up time, though thatís most likely based on your driving style.

Yes. When you delete the egr, you will have a check engine light. If and when you get a tune, just let them know it’s gone and they’ll tune it out for you.

Can you pass emissions without an egr? I think they just hook up to the obf 2 port normally: Iím not sure what they do on diesels as this is my first. Iím in Connecticut.

I took my car through emissions before I started my mods. You will need a cat to pass and as I said earlier, a tune to eliminate the cel or you will fail. They won’t be physically looking under the hood for the egr system though.

What are you goals/plans for the car, how much $ you got, and are you willing to do the work or have someone do it for you?
IMO clean things up, make it all work nicly and keep it stock and slap a tune on it and call it good. otherwise buy a car that does what you want!

I do everything myself. I donít want to try to make it something itís not. If I could get more power without sacrificing fuel economy that would be nice. If I wanna go fast Iíll drive my hellcat. This car is a fuel saver for me. I do like to mess with all my cars a bit though.

So my ahu mk3 Jetta ended up putting down about 230hp on some 764,s, a gt2052, a stage 6 tune, cam, valves, and a ton of bolt on parts and mostly internal stock block. It didnt last too long with my high egts but, while it did, I could get lip into the average of 62 to 63mpg, with a confirmed 72mpg of 99.9% highway 80mph on cruise control going cross country. But that was an outlier!
However I have a confirmed 8mpg when o go do autocross and track days with an average of 18mpg going to the track and doing the event. If I drive it the way I normally do, about 40mpg is about right but all that backroad power!
Diesel power is made by making the same fuel burn better! In a bit shell!

Deleting things wont really get you any mpg better. The only things that will are improved nozzles and more air. Not nessaserilu more fuel, just a better spray pattern and what not.

Here's the catch can I used, search in the MkIV forum for a couple threads
on installation.

No, you will not pass emissions if you have EGR delete .

You can pass if its deleted via a tune but it technically wont pass if it's missing, but inspection/emissions dont know these things. Like you said, they do just plug into the obd2 port and check it. Imo, leave it in place and get it working properly. A catch can when done properly will help big time keeping things clean. You can also get a soft egr tune to help with soot build up. It's not going to rob or gain any mpg doing either delete or leaving it in place.
It does help out a lot to have it functional though. Unless your going full race car, leave it in place and make it work
