Increases Emission Error

J'ai récemment fait une suppression secondaire Cat sur mon e92 m3 et j'ai commencé à encourir une erreur d'émission accrue. Je n'ai pas touché à la primaire. J’ai appelé le magasin et il a essentiellement dit que c’était un capteur et rien de lié à son travail. Étrange si vous me demandez. J'ai lancé un OBD dessus et voici les codes suivants qu'il crachait :

P2432
P2430
P279D
P279

Merci pour votre aide les gars !!

Faites quelques recherches, aucun de ces codes n'a rien à voir avec 02 capteurs.

Même si c'était le cas, ils ne sont pas liés au fait de couper les chats secondaires.

J'ai fait quelques recherches et il semble qu'il n'y ait pas de réponse définitive. D'après ce que j'ai lu, ça pourrait être une fissure dans la ligne de tuyau

Je sais que mes chats secondaires ont été enlevés il y a environ 3 ans (les primates sont toujours présents) et n'ont pas encore reçu de code d'émission accru.:

Scannez avec un scanner bmw, ces codes génériques ne vous donneront pas grand-chose à diagnostiquer

Original O2s, then it's normal, time to go.
My car has 80,000km now and I have done the primary O2s 3 times already.

Thanks buddy ! I'm going to get it fixed Tom . What's your setup like? Would could be reason for it failing

Mine never failed, I never had codes, the dealership/independent shops I go to recommended me to do them. Each time I did them, my fuel efficiency improved.
The previous owner of my car also did them at the dealership before I got the car.

What? This is NOT normal.

doogee is right, it isn't normal for them to go bad so soon but for the s65 its in of best interests to have them replaced earlier as preventative maintenance.

Noticeable improvement of fuel economy as they no longer read as accurate as they once were, the car is also a lot more responsive.

I still have primary o2 sensors that had roughly 30k,KM on it, if you want them let me now.

If I was to get a tune since I'm taking out the primary cat .. would this help with the problem or no ?

Regardless of taking out the primary cat or not, you still need the o2 sensors.

The o2 sensors are a closed-loop system measuring the unburnt hydrocarbons in your exhaust gasses as they escape the rear end. When you are running a car without o2s its called open-loop. Getting a tune only suppresses the light from coming on. If you have other problems/codes happening on your engine, it might not be only just the o2 sensors. Have the car properly diagnosed (take it to a professional instead of doing guess work on the forum) before you start dumping money on replacing things that might not potentially solve your problem.
