Hi

I drained the liquid and cleaned the tray. I filled the missing fluid with new fluid. I drove a bit. After that, I took the tray off again, there were fewer metal filings in it. I refilled the missing fluid again, then replaced the filter. This was 1 week ago, since then I have driven about 100 kilometers with the car both in the city and on the country road, and the problem has disappeared. it works perfectly in all gears and modes, no errors or error codes. I plan to use it and drive another 200 kilometers in it. After that, I take the tray off again and check if there are any metal filings left in it.

Hi, did you solve the problem with gear box allready?
