T6 DSG 1GEAR JUMP

[Wizza]

Hi ,I have an issue with my T6 2017 dsg gearbox on a morning when the vans cold I take it off the drive, it goes up the box no problem, about 400 meters down the road when I brake for the junction it goes down the box into 1st as it comes to a stop with my foot still on the brake, you can feel the van trying to drive through the brakes just for a second (it does a slight jump ) then stops dead as it should do ,it only does it once a day from been cold then drives up and down the box smoothly with out any issues, it's done 76000mls had the dsg box serviced at a gearbox specialist and
they said it had been serviced in the past and they couldn't find any issues with it.

Any body with any ideas
Cheers Paul.

I guess that others might ask for any codes. That is if they are available on the box. I would take it to some where like a specialist VAG or autogear box specialist. See what the others might say.

Really needs diagnostics on it to check the electronics side of it but could be a sticking valve

Cheers guys have had it on a diagnostic checker at a gear box specialist the report showing no problem with the box .

Then it's mechanical, when the specialists did the box did they carry out the correct adaptions

Sounds like faulty solenoid should show up on diagnostics

I'm inclined to agree however they do t always show
