I have a peculiar issue with my car not going into gear when starting it up, or just turning the ignition on actually. It will display the car in neutral/may roll symbol, then the yellow gear cog and the P on the shifter won't light up. It is intermittent though, it may work once and then won't for several other cycles (by cycle I mean, putting the key in, turning ignition on, checking if it works or not, turning the ignition off, removing the key and waiting for the car to go to sleep) and then sometimes it will work for several cycles.
I have my friend who runs a BMW indie shop working on this and he's leaning towards the DKG being the issue. As some of you may know, that thing costs a fortune so we're trying to eliminate all other possibilities first.
We eliminated the obvious and some less obvious things: battery is good (it's new actually), alternator too, checked the wiring, checked that the GWS is not water damaged etc. We scanned the car with ISTA and it says the DKG is "partially communicating" on the LIN bus so we were thinking it may be some issue with the DKG and the GWS. We tried unplugging the GWS but the issue still happens.
The codes we get:
Engine / Motor:
003BDF - PT-CAN, message (request torque DKG, 0xB8): missing
003BD4 - PT-CAN, message (transmission data 4, 0x10A): missing

@aus335iguy I've seen the thread you posted the pictures in and you mentioned intermittent issues as well, are they similar to what I am experiencing?
Anyone has ever seen something similar on another car? Anything else we should try?
Thank you!
