New member looking for advice.

Hi everyone.
I just purchase a 2014 X1 28i Xdrive. 120K miles.

I had error codes P0172 & P00BD, after some quick google search , I replaced the MAF sensor (Bosch) , spark plugs, oil, air filter, valve cover and gaskets.

Cleared the codes and they keep coming back.

I have a few other random issues, like the driver side doesn't work via switch, all other windows work independently. I can use the key fob to roll down/up all the windows.- *I have already bought two master switches with the same results.

The heater isn't blowing through the front or lower vents, and it doesn't appear to be blowing hot air, nor A/C.

Below is the Error Memory report from Bimmer Code:
Any advice will be appreciated.

How old is your car battery? All these non-related Code emerging together may point to a central issue usually to do with the ECU not receiving enough voltage from the battery therefore triggering random fault codes.

It's worth a look at your battery age and strength.

Also be aware that you can't just replace the battery.

You have to register the battery with the car so that it knows to change the way it charges the new battery. Otherwise the new battery will have a very short life.

Why did you buy this train wreck of an X1?

Good call, just ordered a battery from Orileys.

Noted, I have Bimmerlink and Bimmercode. Should not be a problem.

Thank you both for your contributions.
