SMG Error 59: Help needed!!!

[x Spades x]

Is your car on the ground with all the wheels touching the ground when you do the test or are you still in the air?

I had a similar issue or I'm still having it with my SMG retrofit where I would get a similar code. But in my case I don't have a drive shaft connected but I replaced the brand new clutch and pressure plate and I tried changing the slave cylinder and the pld sensor with other ones as well and still had the same issue so I'm currently waiting to get everything back together. Get the wheels on the ground and rerun the test.

ran the test 6 more times with wheels on the ground... no luck.

I know you replaced the clutch but this might be something to evaluate depending on how closely you were looking at other pieces of the puzzle.

Yeah I hear all kinds of metal on metal sounds, when running the bleed tests... but they all fail.

I replaced the clutch with OEM, the pilot bearing, and reused the flywheel. Replave slave 4 times, the gear position sensor, all 4 hard lines, the Salmon relay.

There is an actuator where the GPS plugs into... what does that do and could that be causing the issue?

The actuator is what mimics the shifter in a manual transmission, it does the rotation and forward and backward movement of the shift selector rod of the transmission, the GPS is what tells the system in which of these rotational/horizontal movements the actuator is currently in. Hopefully this makes sense.

What is the current gear the transmission is in? (i suggest leaving it in neutral) - Also, how is the voltage on the system? One last question, if you remove the slave, you should be able to move with your finger the fork, it should have a small amount of play, essentially the distance before it engages with the pressure plate. Do you have this play?

Hope this helps.

I dont think this is related to the pump... Typically if the pump is priming and holding pressure and you replaced your slave with a new one, you should be good. Ive ran into some instances on where the SMG computer gets stuck in an error loop that wont clear unless you start the car, which you have already done.

When you run the slave adaptation, does it make any noises outside of the priming? You should be hearing a tension type of sound which is the rod of the salve pushing against the fork and the TO bearing against the release plate. Its like a metal on metal tension type noise. (hopefully im making sense here)

You mentioned that you replaced the clutch, was it only the clutch? If not, what did you replace?

OP is in new territory with this error code. I've never, in my somewhat limited experience, seen this not be the clutch slave. OP does have considerable pressure loss if only getting two minutes at idle before it has to build pressure again but that isn't necessarily causing this problem.

OP, how many miles on your clutch/pp? Never mind, just reread your original post and saw you replaced it. What else did you replace? Are you still using the new slave cylinder?

Yes, new clutch. I've bought about 4 slave cylinders (3 used, 1 new from FCP Euro). All have acted the exact same. Failing all bleed tests... but it's the ONLY code I'm getting. I have switched the Gear Position Sensor twice... again zero change. I have another SMG pump (used with 66k miles) that I will swap over, since there may be some internal bleeding.

Perhaps BE's SMG Wiki might be able to provide some remedies for this code if you haven't already seen it: https://burkhart-engineering.com/smg...-2c6c5372-a94a

Video of pressure test is below (posted it to Youtube). Thoughts? It doesn't kick back on for like 2 min.

It took 6 sec to pump up pressure -- a little long but this should not cuase reported issue. It took 50 sec to leak down to min which indicates there is considerable internal leak due to aged and wear.

I wonder can you look through the bellhousing small holes to see if the fork/throw out bearing moving when command Inpa to shift? This will prove if slave having oil pressure.

So the new issue only happened after SMG system removed / installed during engine swappping?

He meant the duration time between pump kick on

Posted video in my above comment

The length of time it takes before it has to repressurize. You have INPA so you can watch and clock after it hits max pressure.

What is that, so I can check it?

No oil pressure as in no SMG fluid pressure? I also thought it was weird that INPA shifted into gear with it being unplugged. It wasn't starting with it plugged in because it wasn't going into neutral. Now that it's plugged in, it fails all gears (as well as bleeds).

Ok, inpa shifted it with engine not running, this makes sense; no way it can shift with engine running.

smg has pressure but not in the slave
