[wheelpro]

Hello brothers

I need your help
After rebuild Engine
Every thing was fine
But we heard strange sound from Transimision and flywheel
First we replaced transmission with used one
Sound gone but little
And we replaced flywheel
Sound gone
But after our breakin our engine up to 1000 km
We feel dkg bad
What ever
We replaced flywheel
After that when try to switch gear from parking to neutral or D or R
Car switched directly to p
Fault parking lock disengagement exceeded time
We follow fault by bmw tools
It said check wire
, we checked wire , its ok with function good too , but when we confirmed lock hock good , ista bmw tools said replace Transimision
We replaced too same fault
We replaced mechatronic same fault
Replaced basket, clutches , same fault too
When we unlock parking from under Transimision its switched to N
After that tried to switch to D.or R
Transimision faulty all gear rod failure
Really i dont know what happened
We checked oil many times , filters , all ok too
And checked flywheel its same part we order which compatible with our car
Its sound solved too
We tried to change with donor tcu mechatronic
We found ews protection
And i am afraid to buy another nee mechatronic too
Cause may be its not Issue
When we read all data from dkg diagnostic request
All data read with real numbers , like sensor , voltage , hw number , sw numbers too
Brake pedal on , off
But when i read data from clutches pressure when give car D or R pressure give data zero number
We checked wiring too , ground

For who interested
I checked mechatronic, basket, clutches
Every thing looks good
After 1 week inspection
Finally i found
Suction filter was blocked , and oil pump bad cause filter was too bad
For who meet error before
First thing to check filters
Cause its first possible causes to damage mechatronic, pump , clutches too

Yes, I would recommend the filter check also.
Did you have stock or running the filter that SSP sells ?

What was the suction filter blocked with?
What type of debris?

In order for a pickup filter to be completely plugged, the cause of the material needs to be found. There has to be debris coming from moving parts inside the transmission. Find the cause of the debris, and that more than likely will be your issue.
Plausible causes of debris:
Abnormal clutch wear
Excessive gear material (steel shavings)
Ground up plastic or rubber debris

I had someone send my shop 2014 M5 earlier this year.
A different shop installed DCT upgrade clutches and they installed the parts wrong. Car would not adapt and they drove the car.
Car would not shift correctly and contacted us for opinion.
Removed baskets and found lots of clutch material due to improper installation. Installed new clutches and could not adapt trans.

Fault code :40D408 Pressure comparison, Clutch 2 : Pressure too high

After several attempts to perform adaptation, removed high flow filter and installed OEM BMW.
Transmission adapted 1st try and vehicle now has couple thousands miles on transmission with zero issues.

I changed
Clutches
Filters
Mechatronic
Same fault
When start Engine on p position
No fault
After switching to N only
Transimision faulty directly
Clutch pressure 1 too high
Try to reset torque
Same too faulty too
When i test plane for clutch pressure
Checked tolerance for clutches pressure 1, and 2
Both in tolerance
And ista said delete fault code only
With same cycle.
May be basket ? Flywheel ?
Cause i had bad flywheel ( make noise)
and Changed it

Now after replaced 3rd mechatronic
Still clutche Pressure 1 still too high
And checked basket function good too , clutches ok
When start Engine in p position no fault
After Change from p to N
Fault clutch Pressure 1 too high
When checked diagnostic request
Check photos on N position

i have seen f10 m5 with Fault in hydraulic control after installing ssp clutch and could't do the transmissions adaption ,its always terminated specially in gear learn procedure

then we realized the issue is from the other garage installed 2.2mm ring instead of the 1.6mm ring

u need to check and fitted the clutch again it may be similar issue

Did you try OEM filter #28107842840
I had the same fault code on a different car and the fix was to remove the highflow filter and perform adaptation with the OEM filter

[bavarianmotors]

this is also very possible , u need to try it
