Engine Light puzzle
Had the engine light come on and I took it to the dealer. Their test found fault code 2d22. They then replaced the oxygen sensor and charged me 500$ The engine light came back on as soon as I got in so I brought it back in. This time they found fault code 2bco and determined that the crankcase pressure was below specs. So they replaced the valve cover. The valve cover was just replaced 3 months ago so the parts were under warranty so I just had to pay 300$ As soon as I started driving the car the engine light came back on. Anyone have any idea what's going on? Should I keep throwing money at it? Thanks

Sorry i cant be of any help but here’s a rundown of most of the possible codes associated with BMW/Mini. Your second code, (2bco) lists the following suspected faults:
-Oxygen sensor before catalytic converter defective
- Mass-airflow sensor defective
- Defective injectors
- Intake-manifold pressure sensor defective - Intake-air temperature sensor defective - Camshaft position sensor defective
- Defect in high-pressure fuel system
- Defect in low-pressure fuel system
- Intake system leaking
- Oil cap not sealingh
Leak in exhaust system before oxygen sensor behind catalytic converter
- Poor-quality gasoline
They also state under service instruction to “delete mixture adaptation following repairs”. Maybe they forgot to do the above.

How old is the car, mileage and year? Is it the N14 engine?

Not everyone can afford or want a new car payment. My 2013 N18 has over 130,000 miles. Car is running great and it’s worth it to me to install a rebuilt turbo this Spring.

At so high mileage, something else is coming that will cost more than the car's worth. There is always a time to sell before these problems may happen and take advantage of the residual value.
This is certainly better than wasting money on costly repairs and expensive maintenance. Just my opinion

They will just say it is other things and charge me. I think I am going to try this European auto Care place. I thought the dealer would have the best expertise but I was obviously wrong. The mechanics at the dealer are awfully young

Follow up:
So I took the vehicle to an independent Euro Auto Care place. The engine light code was p171, mixture too lean. They eventually figure out it was the fuel injectors we're clogged and needed to be replaced. So the dealer wasn't able to figure that out and replaced the valve cover by mistake. Total cost to me - 3500$

Similar issues
i have been having similar issues for THREE years. NO ONE can tell me what’s wrong. Latest code for my check engine light is because the CO2 sensors need to be replaced, but I have had both replaced. When taken to a Mini Dealer service department they said they couldn’t figure out why my car’s check engine light was on. So who knows how much $$, and a year and a half expired tags later, I am at a total loss as what to do next. And I have no money to get a new car.
