Bmw 1 series juddering

[Beanie84]

Just to clarify I’m not clued up at all with cars. I have a 58 plate bmw 1 series petrol that started playing up by flashing the driver control system on the dash and the car felt like it was pulling (juddering). Took it to get looked at and showed rear passenger sensor was faulty. Got that replaced and still the problem persists. Did some googling and come across the abs ring could need changing. No codes were coming up showing that the reluctor rings needed changing but changed it anyway. Still the problem persists. I’ve been driving the car and have pressed the DTC button and the car drives fine, it doesn’t pull. The most annoying thing is I’m wanting to sell this car as it was just a second car and I’m going back to sharing my husbands car. Today I’ve had a diagnostic done again and the codes that have come up are:
2EFE Electric fan, activation
2EF7 Map thermostat activation
30EA DeNox catalytic converter sulpherized. Could replacing the coil pack help with this?
Thanks.
