Codes

[whats77inaname]

My battery started dying, and I started getting error codes. In reading the forum posts, members have indicated that the battery should be replaced, and then the codes addressed. I replaced the battery, cleared the codes via the P3, and they have come back. They are:

2722 - Oxygen sensor2 before cat
279D - Power management, closed circuit current violation
274A - Oxygen sensor pump before cat current calibration Bank 1
274B - Oxygen sensor before cat evaluation module in DME Bank 1
2655
260D

I also got these same iDrive messages from this thread (their pics, not mine):





I restarted the car as others have done, and the DSC issue and reduced power message went away. The DSC issue occurred again later this evening, and a restart cured it again.

The information I've read indicate the throttle actuator and the 02 sensors. I'm not sure about the 2655, 260D, and the 279D.

2722 is your fuel pressure sensor. Replace that for sure.
279D - Battery issues (Tons of errors can be caused by a bad battery, so make sure that this is the first thing you sort out).

My suggestion is to clear up any possible battery issues. Voltage should be > 12V with car OFF, and > 14V with car on.

If voltage is OK, replace the low pressure fuel sensor (located in the engine bay). This could have caused your other faults.

If after replacing the fuel pressure sensor you still have faults, let me know I will advise you how to address them.

Thanks, MB. The battery is brand new, just waiting for a cable to address it via the PM you sent me a few weeks ago. Battery is consistently 12.4 w/the car off, fluctuates between 14.4 and 13.9 while the car is on.

I would clear the codes and see what returns. Was the battery reset when you replaced it?

If I was supposed to send you a cable or something along those lines, please remind me.

The battery wasn't reset. I ordered the BT cable and found out it wouldn't work, so I sent it back. You informed me about the other cable (said you guys had it in stock or I could find it online, so I did) and software, and I'm waiting for the cable to come in, at which point I'll reset the battery.
