Got an e90 in the household, engine light and emissions light came up, got bmw sytner warranty who approved the repair.
Sensors (o2 and no2?) are stuck in exhaust and Sytner can't get them out. Sytner saying exhaust needs replacing at £1400 cost and insurer won't cover exhaust replacement.
Sheesh what to do?
Quite common that these get baked onto the downpipes, poor design in my opinion. Must be really bad if they can't get them off - heat and a hefty wrench should do the job. Ask them for some photos and go from there.
