**golf110tdi** · 2nd February, 2019, 07:11 PM

Hello friends. Yesterday I tried to read my gearbox DQ250 with my KESS v5.017 said the ''unknown ecu hardware''. I tried to read with ksuite 2.47 and 2.23 by OBD and on dsg plug but every time kess said ''unknown ecu hardware''.

How to solve the problem. My car is golf 6 2008, but mechatronics is made in 17.11.2016. Could this be a problem.

Hello everyone. I read my gearbox dq250 (golf 6 2.0tdi) with PCMflash. Now I wanna do some adjustments but, I dont know how to correct the checksum. In forums someone said don't need checksum correction, someone said the tools correct the checksum but I am sure that my tool cannot correct checksum.

PCMFlash correct through writing checksum in Flash...

The seller told me that a PCMflash cannot correct the checksum on this file.
If I write a modifica file without checksum, can make a restore with write back ori file.

Yes you are right. I tested it and everything was fine. I figured out how to activate launch control, but something did not work. Thank you for the reply.
