Sorry mate i missed this. I am logging using BimmerLink.
Last night i had a smoother commute home from work (thanks to the emptier roads) and managed to get the issue to sustain itself long enough for the car to throw some DTC's - I got 3x O2 sensor codes. It took a good 4-5 seconds of bogging down for the car to realise it and i didn't get an EML.
The only problem is, somehow i managed to delete them when doing some ISTA diagnosis later that evening
The O2 sensor makes more sense to me than the EGR in my case as the logs show that the MAF setpoint is being reduced. Something is 'telling' the ECU to reduce the air demand.
I replaced my O2 sensor for an NGK one only ~20k miles ago. Ill see if i can get the codes again but ill be ordering a Bosch O2 sensor in the meantime.
