TCU TurboLamik

just a quick question I've recently had an error message from the gearbox when I start the car next morning after turning it off.
First "IL" then the display shows 0001
He used to only do that when the battery was removed.
But now i get this every time. I then have to start the engine and wait 10 minutes until I can engage the gears and drive off. Car is a E30 with 8hp70

Kind regards

I've had the same after making changes in the TCU and power cycling it. Stranded me once, the only way to "fix" has been to wait ~10-15 minutes. I've not had it happen when not making changes to the TCU settings.

IL is not an error code. It just displays before showing the error code.

Error code 001 indicates a problem with the Selenoid Out 1 connection (pin 86 in tcu). You need to check the wiring between the TCU and the gerabox. It happens that the multimeter shows the connection but the pin does not connect, propose to replace the pin 86 from the TCU side with a new one. If that doesn't help, the problem is probably with electronic modification in transmission.

Did you do electronic modification in transmission yourself?

No i do nothing to the tcu or wiring. The error came suddenly

Now i use tunerpro rt to read the tcu. There are 4 errors listed. 1,3,5,33
Can anybody tell me what those are mean?

there's an error list in the download section

How can i delete the errors from the list?
