Technical DDCT oil change - easy or not?

[Buko]

Hi, I would like to change oil in DDCT gearbox and electronic selector. is it easy? just drain and then fill them up with proper oil and quantity or there is a need to do something im multiecuscan? because there are some options there from venting clutch etc.

To change the hydraulic (not transmission oil) you need to depressurize hydraulic circuit, disconnect negative terminal. After changing hydraulic you have to bleed hydraulic circuit in AlfaOBD terminology. I haven't done this myself. Contemplated till i sold the car.

Hmm I just pulled the liquid out of the tank with a syringe and then poured a new one didn’t know how this procedure looks like, should I do something now?

I would at least bleed the hydraulic circuit at this stage.

This option? I have only Multiecuscan

I think this is for manual transmisson clutch bleeding. I am not sure.

No it is for manual transmission clutch bleeding.

hmm but this is the place where I connect to my gearbox and it's DDCT

do you know which option is it in MES or AlfaOBD?

I edited the reply. I read brake pedal as clutch pedal
I would go for it then.

How much oil did you drain @Buko ? I could only drain 400 ml of oil even i depressurized the accumulator tank.

I was not doing that :/ will do it on next oil change. but what I imagine you need to suck out all oil from that container, then take out oil from that robot to container using obd application and option to depressurize, and again suck it out, and then put new oil and use clutch drain option (?) so it will bleed into system, and add some more to container after everything is done. This is how I will do it.

That's what i did. There was only 400 ml of oil in the reservoir.
