Hello guys,

I am in the middle of finishing the project of swapping a DQ250 for my A3 1.8T 8L and wish to share info with you and maybe make a community project out of it.

1st of all, I got a DQ250 from a VW Passat 2007 (a diesel one) and the controller from a Scirocco 2008. Put the gearbox in and make the wiring which is very simple - you have CANH - CANL, Accesory +, Permanent +, Ground and one more wire that goes into the Comfort Module. Same goes for the controller.

Now it comes the tricky part (at least for me???). My ecu was an auto ecu with a manual flash inside (032HJ). The gearbox did not start from standstill. Flashed a 032HF (supposed to be auto) and same thing. Then flashed a 032GH (some NA golf GTI a/t) but I did something wrong in it and the car did not start so flashed back the 032HF. Car started and gearbox works (finally).

BUT -> if I go VCDS and delete ECU error codes, the gearbox does not work again (idk why yet, probablly something to do with ECU coding / flash - will look into it).

2nd problem is, what do I need to flash (ECU ? TCU? or ABS PUMP) in order for the speed signal to float on CAN? I know that DSG does not have speed sensor and only uses speed signal and not send back. I need that in order to make my launch control work (that I heard).

I can help you guys with schematics and other things related to this in exchange for answering the questions above. Let's help the community together.

Best regards

if I got this far don't you think I read the forum? Instead of being a little girl about it, shut up or help making this into a community project. Otherwise you are useless for us.



Back to the project, after some more digging CWGGVFZG is having something to do with where the speed signal comes from.

Hopefully this will solve something, will test today with CWGGVFZG = 1. (now being 0) Also will need S3 facelift instrument cluster because I have a 99' ones and from what I've read it does not support CAN. Will test and report.

Regarding my issue with deleting error codes, any opinions on that? 032HF is auto ecu (regarding it was a HJ flash into that). eeprom shows 11530 coding which translates into: 5 - FWD with ESP and CAN, 3 - AUTO version, 0 - variant a3/golf. Hopefully someone can help.

i will try and report everything I do regarding this. Hopefully others will help. let me know when you do conv so I can help

I really don’t understand people’s need of talking without having something to say

Black hold myself? Are you racist mate?

I don't think black holes discriminate 

Anyone swapped into a mk4 with mark20 or mk60 abs?
