I have an automatic 2008 E93 335i and the tranny has always been a bit rough but I never received any codes from it. However, last night I got my codes read at Autozone after going through a transmission malfunction and I had the codes listed below. I believe that this is due to the Transmission Control Module going out, but I'm not too sure. Could anyone help me diagnose this? I don't want to make any purchases before I know for sure. 

symptoms are...

- rough gear shifts (esp 3rd - 4th)

- random down/upshifts at low speeds

- rpm flutters in neutral

- transmission malfunction every so often

Any help or suggestions are appreciated!!!

You need the help of a transmission specialist: preferably a ZF Agent your problem could be that a transmission service is due/overdue. Low transmission fluid levels, failed or failing solenoids in the box a specialist will be able to give far more information

      Rough idle problem

      Looking for some help. 2010 116i M sport with the 2.0na engine. When cold, car ticks over perfectly. After about 15 mins of driving when idling you can feel it getting a little bit rough. Nothing too bad, but the longer you idle the worse it gets. No EML. When running car runs perfectly not a flicker. Today left it idling for 10mins after I felt it and then revs started to fluctuate but still no eml. OBD scanner can’t pick anything up. Turned it off and back on and was still rough but only a little bit like when it just starts. Anyone had anything similar or can point me in a direction of where I should start looking?
