ZVW  DSG 7 0AM mechatronic issue
Hi there guys, I have these intermittent errors on the gearbox.It is overreving and not changing gears from time to time but I haven't got any errors until yesterday.When interrogating the DSG ECU had those 3, attached in screenshots.
What could be at fault? The hydraulic accumulator?I've seen a repair kit for it but also for the other components too,
Thanks

Did you change oil filter when changing oil in dsg? Maybe sensor fail but check dsg filter. You can check accumulator manual with manometer to see if correct pressure or broken “balloon “

This gearbox doesn't need oil change.It has 1,8 l capacity and mechatronics unit and gearbox itself have different oil circuits.

First check oil pressure of inside mechatronik, if below than 42 bar , it need repair. Dont make basic settings if pressure is low than 42 bar.

Yeah, you told me that from what I remember but the fault is intermittent and even more, it appeared yesterday after 2 months.That pressure drop gives me some indication that I should replace the hydraulic accumulator.Nevertheless, i ll take a look tomorrow at the pressure.
Thanks

So I checked all the pressures I could see, there was nothing below 42 bar.

I can repair it in Poland with 400$.But firstly I ll change the hydraulic accumulator and its casing.If that doesn't work, i ll send it to Poland.
Does anyone have another opinion on this?
