Could you help me with code P2626 Bank1 Sensor1? I'm assuming it's the precat o2 sensor.
Thanks in advance!

Most likely you're looking for 2b26. The display in a lot of code readers make it hard to tell the difference between "b" and "6."

Sorry, I only have ECU fault codes, not tranny fault codes.

Any idea where I can find tranny fault codes other than the dealership?

Sorry, I only have ECU fault codes, not tranny fault codes.

Any idea where I can find tranny fault codes other than the dealership?

We can read them remotely if needed. Other than that, an independent shop with a BMW specific tool should be able to.

Fault code 5A43? Came up for my DCT once.

Can't find it anywhere.

5A43: DCT Pressure sensor, clutch 2, total failure

This could mean that the pressure sensor is reporting incorrect values, that the pressure sensor circuit has shorted or that the circuit is open.

First thing to do is to read the sensor data from pressure sensor on clutch 2. It's supposed to be within .2 and 1.8 bar pressure.

If the pressure sensor is reporting incorrectly, it needs to be replaced.

Otherwise there is a hardware issue or fluid issue.

This fault will cause clutch circuit 2 to be turned off, which will prevent selection of gears 2, 4 and 6.

Hope this helps.

It absolutely did! Sending you another PM regarding this.

How about 27c3? I thought it was the gas cap but just bought one and it came back. Then read it was the dtml pump but read another guy had this code and replaced his pump but it didn't fix it. His last resort was a leak somewhere in his exhaust and he needed a smoke machine.
