Consequences for driving with CEL? (180001, and 180101)

[msdss]

I have a 2017 X6M, it's throwing 2 codes. 180001 and 180101. I believe this is from faulty pre-cat o2 sensors.

Does anyone know what the consequences of driving the car like this are? More specifically, is the car going to run rich as a safety precaution? I'm about to leave on a road trip to CO, and the car already gets dog shit gas mileage.

My dilemma is that I can get the parts shipped, and save $200 w/lifetime warranty from FCPEuro, OR pay $300 more, get the parts right now from BMW and fix it, and not have a lifetime warranty.

I'm supposed to leave in 2 days... So if it isn't going to kill my gas mileage, then i'll ship the parts and do it when I get back. Else i will probably end up saving money in fuel by doing it right now, and paying more for the part.

UPDATE: To answer my own question, the car will run rich. gas mileage will be total trash. replacing the pre-cat o2 sensors resolved the issue. part # 11787576673

If that's your only vehicle, then fix it before you go on your road trip. Why risk getting stranded or damaging the engine or other component to save a few bucks? While the warranty is nice, you need the vehicle running, and it sounds like you need it running now.

Just my $0.02.

Well that's my question right?
What are the consequences of driving the car with these 2 codes?
If the answer is nothing, then im going to save myself $300, and fix it when I get back.
If the answer is something, then i'm going to fix it now.

Any mods?

Reduced fuel economy should be the bulk of it. Lets say in theory that the cats are still in good shape, and this is only a sensor related issue; you could potentially damage them - resulting in a high ticket repair. Otherwise you should be fine.

All the best and keep us posted as to how things turn out.

No mods. Stock car.
I assume that running off a default table instead of live data is all thats going to happen. But the table is going to have richer fuel maps for safety reasons.

I just said fuck it, and bought 2 pre-cat sensors from BMW. I'll throw those in tonight, and fingers crossed the codes go away.

For anyone looking for assistance with this code in the future...
I replaced both pre-cat o2 sensors and the issue has been resolved.
