Passat B7 DSG 7 problem
Hi there guys, I have a 2013 Passat B7 with DSG 7 transmission, 1.6 TDI engine.The problem is that it downshifts and accelerates madly from time to time with no errors on the transmission control unit.Is it the clutch pack that needs to be changed or is there any other problem that they tend to develop.I don't have a lot of info on this DSG with dry clutch pack.
Any thoughts?

Have you checked fault code? Oil? Have you changed oil?

First measure real pressure of oil in Mechatronic unit. if below than 42 bar, need repair or change.
Second , if oil pressure is normal , then make basic settings
Then you can write result or contact me

What do you mean by real pressure of oil? To physically measure it on the gearbox? At the moment, I couldn't do that, but I will check the pressure in ODIS.I do know that mechatronic unit has its own separate oil circuit in the gearbox.If I don't see something unusual in pressures, I will check basic setting and report.
Thanks!

I tried to read the car today but the battery of my laptop is fried and couldn't do it smile.
On the other hand, when it is badly shifting, if you switch it
to manual, it will work flawlessly.So, the clutch pack it s not the issue here.

Hi, if your gearbox code is one of the following : QJG MPH NRQ NDB PFD NTP PLK PRB PTG QRQ

The latest software is      v069FR100AM___getriebe_DSG_OJFR_sw.sgo   (0AM300063K)

Sometimes updating the software makes a big difference.

If it is not one of the above then please let me know what it is and i will give you the correct software.

I have found many vehicles with the wrong software. Sometimes other mechanics change the mechatronics with a used unit from more or less the same vehicle. I recently had a unit that was incorrectly flashed by a VW dealer. They flashed the vehicle with what the server supplied and that software turned out to be incorrect resulting in a poor performing DSG.

Hi there, the gearbox code is PMK.Can you provide the latest flashfile for it?
