DCT overheating

[Eileen]

I have a 2013 135, low, miles (55,560). The DCT temp indicator (picture below) came on amber and immediately switched to red and shut down the engine of my car. I waited a minute, restarted the car and it ran fine. I was not driving the car hard. It was around the town driving.

I took it into a BMW dealer and they claim its a water pump issue. That does not make sense to me as my understanding is the DCT transmission cooling is separate. Can anyone advise me here?

I believe the trans cooler uses coolant as an exchanger. So they advise replacing the water pump? Have you pulled any codes?

Hi Eileen,

interesting input. I have had the DCT heat issue over years and long story short believe I've finally solved by replacing the (aux) water pump which I assume your dealer refer to.
Went to couple of different shops incl main dealer who had no clue and could not comment on my thoughts about the pump. Congrats, you seem to have found a BMW dealer who actually knows its products!

See this thread for further details. Let me know if you can't access the tech desciption ref to and I'll post it separately: https://www.m3post.com/forums/showthread.php?t=1772232

Ps. Posted this reply on the M3Post as well. Reply/post possible questions there as I'm not regular here. https://www.m3post.com/forums/showthread.php?t=1903696

Any updates on this? I have the same problem. Dealership wants to toss a whole new dct at it. Inspection report from dealership shows overheating trans. Codes but no cause. Warranty company inspector drove the car and canÂ’t duplicate the problem. Warranty company deems codes not sufficient to have the dct replaced on their dime. 2013 135 64000 miles.

Snarfnaj, did you get your DCT issues resolved?

FYI there is no aux. water pump on the e82 dct. If your e82 dct is overheating, you probably have a stuck thermostat in your heat exchanger. The solution is to buy a new heat exchanger, part no. 17217536929 (the thermostat does not have its own part no.) Although the transmission itself is identical, the cooling system is not, and you can see on realOEM that the e82 has no aux pump (Helmsman) .

Crazy oveaheatiing issues about these DCT trannys at such as low mileage. I don't think I ve seen these overhearing isues in my ZF transmissions.
