DCT malfunction

[T!m3]

Hello! My DCT died(( I was driving my car, than something happen,
transmission malfunction light came out, and a strange sound,
like metal rubbing on metal, until after a few seconds dct itself switched to 2 gear and went only on it,
sometimes even the engine speed was falling down, and u cannot control it, no reaction to the gas pedal, car just stopes! so I had to restart car, put myself on 2 gear and barely move my poor m3!

Sorry bad english!

OBD2 codes
5a73
5a63
5a61
5a6b
5a6d
5a74
5132
5a62
5a44

5A44 = P17A1
Fault text DKG: Clutch 1: incorrect pressure
Fault description Clutch 1 Hydraulic Circuit Pressure Too Low


The others I do not recognize.

Maybe is just the clutch died

Maybe you had a fluid loss and locked up

Diagnose possible faults in your mechatronics module.

Im having the same issues.
my m3 won't shift out of N.

error codes displayed are:

5A61
5A63

according to a diagnostic tool it said that the faults were rod actuators.

anybody have Amy idea what this is? or have any details about the error codes presented above?
iv given my m3 into the bow dealership for a fault diagnosis so will keep you posted as to what comes of it.

Any updates about your issue? Today I did a hard brake and CIC/dash threw a transmission fault and wouldn't select 1st or 3rd during driving but all other gears were ok as I drove it. I turned the car off and on and everything was back to normal again and no errors on CIC/dash.

When I got home, connected to ISTA-D and got codes 5A61 and 5A62 about selector rod. Maybe the DCT is low on fluid and as I braked hard the fluid shifted too much with one end with plenty of fluid and the other end empty? I'm going to get the rod bearings done next month so will get the mechanic to take a look at the DCT fluid level too.

I'm also running GTS tune if that matters.

I had similar things happen once or twice while autocrossing it. No clue what the deal was, maybe fluid sloshing around from repeated quick movements? I'd get back to the pits, turn the car off, turn it on again, and things were fine. Drove the car for several more years without issue.

DCT is just fickle sometimes.

Thanks for that. I was changing the 2 precat O2 sensors yesterday and noticed the transmission pan was oily at the bottom and fabric cover was oily inside too. So will definitely get the pan, gaskets and new oil done when I do the rod bearings next month.

If it's leaking, you're obviously low on fluid. That's not going to help things, but if it's only down a little bit I don't really think it's a huge problem. The sump is sizable.
