Hello, i'm facing a problem with this swap from a DQ250 to DQ500 on an already swapped TFSI manual converted and fully worked DSG car.

Gearbox is mounted, car is work but i got a lot of problems and lights on in instruments cluster

Automatic/manual upshift/downshift are working, but if you change in manual gears number in cluster don't appear.
If you go slowly... car is moving, if you press pedal a little, happens the end of world  

Anyone of you have tried to swap this gearbox and help me a little to solve the problem?

If you need a some DTC...in attached some screen.

Looking for an hand

[UPDATE]

The problem was a skinned wire of the steering ecu that create interference ...and the whole car went down to 7 voltage and it didn't work. Indeed if we by-passed the steering ecu ...everything works well.

No we have last problem.

In manual drive, there aren't gear number in the FIS, but only square.
I assume this is a software problem...maybe the TDI stock file...anyone of you can suggest a file version to use if it's that one the problem?

Regards

After flashing another sw version, 0BH300011N 1411, the gear number are visible in FIS. So this problem is fixed.

I still have gas pedal problem… when you are cruising in D and S car is perfect…when you switch in M (manual) after a couple of seconds, gas pedal stop working, car not raise rpm (and go down to 1000, without gear inserted, to move again you have to switch in N and D , after switching …in N, car get again engine rpm and pedal start to work perfectly.

Any suggest? 

Thank you for your answer.

i've though something like this, because i've tried 2 softwares and both the same problem... so i assume is not a file problem but something else. I've though also if it was a file problem ...also D and S should not work...instead...they work perfectly(seems) and only M has problems

So you think something in CAN comunication? between ECU and TCU?

How can i check those variables ?
