Katalizator

[tomasm]

Hello,

I had same issue with catalyst. It consist from 2 parts (B + C). The ceramic inside the first part (B part) of catalyst has broken and DPF was burning very often. In car service they cut the catalyst and cut off the broken/burned filter from B part. Then DPF burning was solved. After this procedure, there is an error 9569 - NOx Sensor 2 Bank 1, P229E 00 [237] - Electrical Malfunction.
I would like to ask if you have also error with NOx sensor?

I bought original used catalyst and there is also B part broken (attachment). I have same error with this used catalyst. Do you think it's due to broken B catalyst or something has happen with NOx sensor and needs a replacement?

Thank you.
