Passat dsg problem

[Autel]

Hi I have a Passat 1.4 TSI with dsg7 gearbox. First, I got the problem with the chain and fixed it. Now I have even bigger problem with the gearbox, at first it went just to 1-3-5-7 gears and it was difficult to get in Reverse. Now, if I really try many times it goes into gear 1 but when i start to drive maybe 100 meters it goes to neutral if i try a bit more , it can sometimes jump to the third gear but soon it goes to neutral again. I have scanned it with ODIS and got codes like: P073E unable to engage reverse, p072c stuck in gear 1, p073a stuck in gear 5,p072d stuck in gear 2,p074a unable to engage gear 2, p074d unable to engage gear 5, unable to engage gear 1 and so on. All help whould be appreciated.

Just a though...
Think is time to leave the laptop and take the toolbox
If you do take that gearbox apart, post some pictures ,for educational purposes...
