CBFA Highflow Cat/Testpipe CEL Fix Thread

[vath]

yes CCTA do have a o2 sensor right at the top of stock DP, this you can leave without a spacer(2 total)

the CBFA motor has the top o2 sensor on the other side right at turbo, it is not on the DP on CBFA. Then one before and one after cat(3 total). This is why CBFA is so touchy to get CEL free, its constantly taking all these readings!

OOOOOOH

now that i know the CCTA only requires 2 total o2 sensors.... now i know i should left the plug where it was....

Well at least you figured it out. The 1st o2 sensor goes into the turbo itself and you plug the 1st bung on the downpipe.

I moved from STL to KC and KC doesn't have emissions.
Im getting flashed to APR stage 2 testpipe file this weekend

[cubantexan]

Hey guys,

Just got flashed with the non-testpipe file and I have my O2 spacers installed on the testpipe. I have no CEL which is good but when I ran vag-com for OBDII I saw the messages below and thought it was odd.

Mode 01 - PID 01 : Readiness -- Address 7E8

Number of DTCs stored: 0 -- MIL Status: MIL OFF
Misfire monitoring: Passed
Fuel System: Passed
Comprehensive Components: Passed
Catalyst monitoring: Failed or Incomplete
Heated catalyst monitoring: Not installed.
Evaporative system monitoring: Failed or Incomplete
Secondary air system monitoring: Not installed.
A/C system refrigerant monitoring: Not installed.
Oxygen sensor monitoring: Failed or Incomplete
Oxygen sensor heater monitoring: Failed or Incomplete
Exhaust Gas Recirculation: Failed or Incomplete


Will I still pass inspection? What do those failed or incomplete mean?


Thanks all!

Having no light on and the computer giving you those readings, i would say that the file you had flashed permantly has those monitors shut off. and depending on your emission laws you may fail even though your light is not on. Here in MA all those monitors need to be ready and passed.

I have no o2 sensors in my car and my flash has all those monitors shut off so the light does not come on and i just tried to get my sticker and i did not pass because of it. so i need to put the o2's back in with spacers and get a reflash to turn the monitors on.

I just passed emissions 45 mins ago with my car..

I have a 42dd 3" downpipe and cat (magnaflow 200cell?). I had a testpipe in there for a while, as well as the v1.2 stage2 testpipes file, so I knew I would have to get reflashed to get rid of the two not ready errors. In the meantime I ordered two of the RAI J spacers (made by vibrant), and I installed them the other day. I put one on the 2nd and 3rd o2 bungs. The 2nd one I put the medium spacer, and the 3rd one I put the small spacer.

Yesterday evening I got reflashed to the v1.2 regular stage2 flash, and was able to set the readiness by driving home, then to work in the morning, and then to lunch today. I checked my readiness with Vagcom at lunch, and everything said passed, so I figured I was good. I made an appointment for 4pm today, and it passed with no fails or not readys.

Nice, this is the configuration I was planning on trying out. Thanks for reporting your results

Can you take pictures of how you placed the spacers. Or just tell us which direction the J is facing.

both pointing straight back. There wasn't any way to point the front one forward or down really, just no room, and the rear one I wouldn't have had enough length on the wire.

If you ever get a chance a picture would be nice. I'm not familiar with the o2 sensor positions on the 42dd downpipe.

Edit: I was forgetting. Your garage build is insanely awesome

lol thanks.. actually I need to update that badly.

anyways, here's the pics:

[vath]

just an FYI...

I am 2009 CBFA motor with APR1, BSH intake, and APR downpipe (stock exhaust) . I had a CEL with only a 42DD O2 spacer on the last downpipe port...

Then I installed a BFI O2 spacer on the 2nd port and all is good now, I cleared my CEL and drove about 75 miles so far without a CEL and today I checked VAGCOM and all the Readiness is PASSED

thanks for the help guys!

edit: The BFI exits to the rear and the 42DD exits to the front if anyone cares....

Bringing this thread back to life. I just installed my SPM DP and paired it with two 034 o2 spacers. these are the L shaped spacers. The last one I used a double spacer config using a normal spacer after the 034.

This threw multiple codes after 60 miles. I don't think the sensors are getting enough exhaust flow with this setup. I'm going to try just using a standard anti fouler (pre drilled from factory) (2nd sensor) w/ an 034 on the 3rd sensor.

Hopefully this works. Although I am skeptical because the precat sensor w/ 034 spacer threw a code. Spacer is facing the rear of the car, and I got a code stating it isn't getting a good reading.

[ViRtUaLheretic]

Were you throwing too rich or too lean codes for your o2 sensors?

[ViRtUaLheretic]

Its reading rich, you should use a smaller venturii to restrict the flow even more.

[lilfleck]

hm... okay. Looks like I'll have to buy more spacers

What about the slow response code?

[Slayer]

Pick up a couple of the rai spacers instead, they will probably work

[lilfleck]

you know what doesn't make sense though? When I initially installed my DP, I only ran w/ one normal spacer in the 3rd sensor spot. It drove for 170 miles before I threw a code. Now I moved the sensors further from exhaust gases, and I get the CEL quick?! It's coming on after 10 miles or so now w/ the setup I have currently.

[Slayer]

it's touchy, but I think the rai spacers are the way to go. I put mine on, got reflashed to stage2 non testpipes, and I've been through 4 full tanks of fuel since then (~1600 miles), and it hasn't come back

[kaban]

I've not had the p420 CEL code come back after 10k miles of driving. The RAI spacers is the way to go.

What code are you throwing? rich or lean?

You cant be too restrictive otherwise it will read lean and still throw a CEL

[lilfleck]

Hm.. the first code i threw was P0420, efficiency below threshold. Possible leak? I only had one normal spacer post cat.

don't mean to derail this thread much, but those codes that popped up, are those manufacturer's codes? So this app can scan for VW's codes too?

Pretty sure, yes. You can also run logs/graphs, see live readings from your car. Clear codes. Completely worth the $30 I spent for everything. I would do it again in a heart beat.

I would LOVE to have run some logs and compare them to others who have beat the CEL on CBFA. I just don't know which readings would be important to log this issue. I'm thinking either o2 temps and/or o2 voltage. o2 voltage seems like the better choice bc i can actually select sensors #2 & 3. When I try to read o2 temps, I can only read 1 & 2.

[jokerny77]

Don't wanna beat dead horse here but, I just installed a eurojet tbe w/cat (no flash yet). Got the standard codes today p0420, also a too rich code bank 3. I have the standard L shaped spacer (pointing towards the front of the car) on the post cat o2 sensor. Should I also throw one on the pre cat or should I go with rai j spacers on both pre and post cat o2 sensors so I can also restrict the flow to the sensors?

[Slayer]

two of the RAI / Vibrant j pipes are the way to go.. you get a lot of different options to make it work for each car

[jokerny77]

yeah I read a bunch of different combos, thinking the rai w/medium jet in the front and smallest jet in the back

[eduardot]

I'm currently running an SPM downpipe using one J spacer post-cat with the medium-sized jet. I've only traveled 300 miles, but no CEL yet.



There are two more users on golfmk6.com with the same setup. Yes, we are CBFA, I guess it's just luck that it's working with only one spacer.

[jokerny77]

and your pointing it towards the front, spoke with someone at eurojet they said point it towards the back

[eduardot]

Does your eurojet cat section look like mine? If so, maybe you could get the same results. I'm just asking because when SPM just came out there were a lot of talks about how similar they are.

Also, I have an extra J spacer that I could sell you since I ended up only using one.
