Hello from Romania.
I have done a dq500 on my 2010 Leon tdi big turbo , 340hp/605nm, 3 months ago and everything works nice. I've done about 5k on this gearbox, pretty happy with it.
I just have an error similar to yours (databus). Should i replace the gateway also and code it?
I went from dq250 to dq500 from audi q3 2014 NYD gearbox, similar to yours.
If somebody needs help with the wiring its pretty simple, i have the connections saved, just removed pins from old dq250 connector and plugged into the new dq500 connector.
Right now i will have a new software prepared for it with improved shift times, 750Nm torque limit, kickdown removed plus some other tweaks and increased clamping pressure on discs.
If you can offer some info regarding the gateway would be very nice. I left my original one in place and have the databus error.
Thanks!
Hello and well done with your swap, have you gone AWD or stayed FWD? I've just finished the swap for AWD on mine now!
The Gateway needs to be a 2010 onwards part (which yours could be but worth checking)
The part number for my gateway is 8P0907530C which is from a 2010 onwards A3 but 7N0907530N or 7N0907530J should also be OK - I looked for something that was used with the DQ500 from the factory so A3/TT/Q3/Tiguan/Transporter
I still have an error for a missing signal from the Canbus in the gearbox - but it seems to work as it should so I've not looked any further into it (although I think it is the diagnostic communication with the instrument cluster) It might just be a case of swapping the instrument cluster for a later one but I'm unsure, it's quite a lot of money to get rid of a fault code which doesn't actually seem to make any difference. I can send you a screen shot of my fault code to see if it is the same as yours?
Thanks
Alex
