Quick update on downpipe spacer setup. I was able to eliminate the post-cat o2 code using the Vibrant J spacer (Vibrant p/n 11619) with the medium insert. I used a spacer only on the post-cat o2 sensor. After a few days of driving readiness set! Still good after ~250 miles of driving. I'm glad I found a solution for getting through emissions. Pic of the medium insert in the spacer:




I've also set up an appointment with a local VW dealership because it sounds like they may be able to replace my radiator under warranty due to a faulty G611 sensor. It's been causing constant soft codes U102F and U1030 along with the occasional CEL for a few months now. Unfortunately the sensor is tamper proof and cannot be purchased separately from the radiator.

Right about now I'm really wishing I owned a CCTA car! CBFA is a headache.

Man, I have CBFA as well and I had a hell of a time getting the CEL light off and it still comes on every once in a while even with a pre and post cat spacer. The ECS downpipe looks like the post cat bung is already spaced a little, so that may have helped a bit. My 42DD downpipe did not. The only DP that guarantees no CEL on cbfa is the AWE one.

Yup CBFA is a real bear. I never managed to get readiness set with my previous catted downpipe. I fully expect to pop a CEL at some point but the fact that I can even set readiness is already an improvement.

Now I'm deep into the battle with the radiator identification sensor and trying to get that issue resolved short of buying an OEM CBFA radiator for $300.

This is strange. I was able to pass 3 inspections (2 PA, 1 MD) with that downpipe. I used a straight spacer from RAI with med jet and had no issues. Hoping I can do the same with my Eurojet setup as I'm due for emissions in a few months.

To be honest I didn't mess with the spacer setup too much since I wasn't due for emissions while I had the old downpipe on the car. The only setup I used was the Vibrant J spacer with the small insert.

I assumed if I could keep the CEL off for a reasonable amount of time then readiness would set...apparently that's not the case since I went months and thousands of miles on that setup without popping a CEL (it only popped a few times in the 1.5yrs I used that downpipe) yet readiness wouldn't set.

Oh well, I'm all set now

Much appreciated sir. I've benefited from a lot of your advice and wisdom posted on this forum.

In other news, I had the opportunity to ride in a coworker's brand new A4 today at lunch. No doubt an amazing car, particularly the magnetic suspension, but I don't think I would ever want one. I didn't particularly like all the electrical gizmos, screens, and nannies. Most importantly it was missing a pedal

The only car work I have planned right now is working on dad's MK7. Got a TTRS clutch, poly control arm bushings, and lowering springs all sitting in boxes ready for him. Should be a piece of cake since I've done all those on my car already . Maybe I'll take a few pics and throw them up here.
