2012 EGR delete, P2002 code

[jhatch89]

My first post so take it easy on me. I have a 2012 sportwagen that finally got the P2002 code and I have soot at the tail pipe. I'm assuming my EGR is cracked and wanted to see what options I have. I figure I can either replace the EGR with factory parts and wait for it to happen again or delete the system. Factory replacement seems pretty straight forward but the delete process and what is actually required is confusing. I would like to do this as cheap as possible without compromising the integrity of the car. If I go this route, what do I need to properly delete it? A few companies would be helpful too. My inspection guy said he only looks for catalytic converters during inspections so thats the only thing I need to stick with for a delete.
Thanks everyone

The DPF is what cracks, not the EGR. Usually when you delete the DPF you can leave the EGR installed, and just tune it out. As for where to shop, start browsing in different threads here.

Do I need to remove the oil cooler too?

Oil cooler with oil filter will remain in place.

Delete process is the same as factory replacement, except you are replacing the DPF with a free-flowing downpipe. Then, due to factory equipment not present, you will need to flash tune your ECU with a tune from any number of vendors. You can certainly retain your cat if desired, depending on which kit you use.

I was looking at the EOCperformanceparts. Looks like I can get the exhaust, blocker plates and tuner for around $1200 vs the same kit from Rawteck for $2100. Any thoughts on the quality of the EOC vs Rawtek and if the saving is worth is.

I personally used the EOC kit on our 2013 Jetta and really liked it. One thing they have over other tuners is they force readiness. So, if you need to pass a plug-in OBD2 scan it will most likely pass. I never got to test that out as the car was totaled by a careless semi-truck driver.

Also, you can sell your old, cracked DPF/cat to a scrapper and recover some money (~$400-450).

I cleared the CEL and currently have around 300 miles on the car without it returning. I also ran it on the high way for roughly 150 miles. If it comes back which I'm sure it will, I will be buying a kit. Any other items I should buy that aren't included in the normal kits? From what I was reading, I needed to get a "race pipe" and some brass fitting for the coolant to core rerouting?

Not necessary to physically remove the EGR valve or bypass the EGR cooler. However, removing the EGR valve will make oil filter changes a little easier. You can get something like this:

If you're referring to the EGR cooler, that can remain or remove, your choice. If you do remove it, you'll need a 3/4" barbed 90-elbow fitting to join the hoses together.

Alright so I think I've decided my route but wanted some feedback. I'm going to purchase the EOC kit stage 2 with the DSG tune and an extra v-band. I plan on putting the exhaust in and somehow utilizing my existing CAT by expanding pipe or weld directly. If I install the blocker plate at the EGR l, do I just put the plate between the pipe and EGR keeping everything together but blocked or do I block off the EGR and remove the pipe? That's the extent of the replacement I'm aware of unless someone thinks I should do more. Thanks everyone.

When you remove your DPF and EGR filter (on the low pressure, outlet side of DPF) it leaves an opening where exhaust gasses would have gone into the EGR cooler and then back to the turbo. That opening will be covered by the blanking plate.

The high pressure EGR tube which goes into the EGR valve (visible from the front of the engine) is left alone and intact. The tune will just keep the EGR valve closed all the time. You can buy a part like the one I linked in my post #8 above if you want to clean things up, but it is not necessary.

The egr blocking plate belongs back at the exhaust manifold, not up front by the egr.
