M3 DCT mode coming out of reverse

I'm new to DCT. When I reversed and put the shifter back to D/S, why does it put it into auto sometimes and gear 1 manual sometimes? Sometimes it doesn't put it back to the mode it was in before reverse. If it was in auto drive mode, I'd expect it to go back to auto drive instead of manual gear 1 after reverse. This makes shifting unpredictable without reading from dashboard to confirm what mode the DCT is in. Also, it also seems to have this random behavior when going from P/N to D/S.

Should I get it checked?

Chris, when going from park to gear.....it will default to D3 by design. It doesn't matter what your last selection was. Now from reverse to gear it should recall your last driving mode assuming you entered into a drive mode first. Let's say you have to back out of the garage in the mornings.....then it will again default to D3 because it will always be the first drive gear the computer selects. Hope this helps........Phil

Thanks, Phil. When I pick up my M3 again, I'd pay more attention to what I was doing. Probably a user error on my part. I might have pushed the shifter to the far right when returning from reverse. My muscle memory from shifting a MX-5 probably carried over when shifting the DCT shifter.

I have observed that in my car that if the car has not gone into sleep mode, reverse to forward will recall your prior selection. If I am driving in S mode, make a quick stop, back out of the parking spot, the car will return to S mode. If it has been a while (more than 15 minutes or so), the car will default to the D3 mode that Phil highlights, as does P to a forward gear...
