Hi, after more engine maintenance, which also included cleaning the EGR valve and removing the swirl flaps, I started getting DPF errors...

Specifically:
4667 - too frequent regeneration
4185 - exhaust gas temperature sensor before the catalyst

Regeneration takes place very often, roughly every 50 km. The strangest thing is that even though there is no requirement for regeneration in the ECU, it still happens. See the screen here - https://angelosss.rajce.idnes.cz/BMW...ems/1593273520 , I'm sorry, it's partialy in Czech language, that's why it's translated next to it.

Exhaust gas temperature sensor before the catalyst works correctly. Only for some reason the temperature rises quite high (about 700-800 °C) during regeneration, that's why I think this error pops up. The values can be seen in this video - At 3:39 it can be seen that the regeneration of the filter starts. (This is the second line in Ista)

My question is - Is it possible that the missing swirl flaps would cause errors of too frequent regenerations?

Thanks a lot
