Possible CEL fix for catless DP's

Right, so I had that in my 1.8t mkiv GTI catless DP with a 90-degree elbow before I got an APR tune, and it worked. But, that was a '06 VW/Audi ECU, not BMW DME.

Has anyone tried this on the n55? Has anyone tried this on a different BMW engine and found it works? Bueller?

tried

, didn't return anything

I would also like to know this.

From what I've read it seems like there is a fix for the N54, but nothing for the N55 as of right now.

Both the Cobb and jb4 should clear the CEL from downpipes.

Andrewe92 · 05-15-2014, 11:31 AM

^^^ this, I don't even think anyone is working on a fix for the n55

That just hides it from the dash. Come emissions time it will be detected.

Exactly! But with the mini cats in between the o2 sensor and the downpipe, the O2's reach readiness state and never throw a CEL, therefore allowing us to pass emission.

There is really no way of knowing for sure unless someone tries it out and returns with a passed inspection.

Except I have not seen it work for any BMW yet.

Please point is to something that shows it does. Many of us are waiting for anything that will prevent the flag.

I haven't been up under the car. i assume i need an 90-degree elbow? would i need anything else? and i do need two sensors for an n55 xdrive?

'preciated. will report back with results once it's done. won't be too quick, need another paycheck or two, but will be an actual fix instead of the Cobb or JB4 just not displaying the CEL

Yeah there are two o2 sensors that go into the downpipe. You don't need a 90 degree one. I've been using the ones I posted the link for for a little while now and have had auto clear off on my jb4 and still no code. So they work, at least on my car.

need to try this myself... if it sets it to ready and no SES then .... AWESOME

Jsoboti · 05-19-2014, 06:59 PM

Anyone else done this on an N55 successfully?

Slops · 05-20-2014, 07:47 AM

i would have tried this asap when i had my car... been looking for something this easy the whole time i had the car. SUch a pita to take the dp off every year for inspection in PA

davidoh1989 · 05-23-2014, 09:03 PM

any news on the n55? i live in ga.. and emission is killing me.. im itching to get a dp but cant..

Knonsense · 05-27-2014, 06:05 PM

I've ordered the parts, have a catless DP waiting to go, and will install when i find time off of work. I'm hoping first/second weekend of June.

sounds good

Jsoboti · 05-27-2014, 11:48 PM

I have the mini cats and a DP on the way. Should install next week. I'll post the results

Cure12 · 05-28-2014, 10:33 AM

Exciting Stuff...Hope it works out well...

Jsoboti · 06-03-2014, 07:01 PM

Put my VRSF downpipe on today which was a MAJOR PITA btw. Only one of the mini cats actually fit so I think I'm probably going to get a CEL soon, I'll keep you updated.

The fitment doesn't really allow for the mini cats because they're so long. maybe with another brand the 02 sensors go in a different place?
