RE: Need help with winkfp, downgrade DDE
Have you looked at LIVE DATA???

P.S. If you must flash first, fix later, then I don't understand WHY you can't use comfort mode and enter ZUSB number manually into WinKFP and insist on using expert mode instead???

Original 7809200 you have to use 7809000.0pa 7809199.0da 06DDE71.IPO 03DDE71.PRG address 12 if you use data 27 but it will be the same as 8506834

The car is fitted with Zusb 8506834. But we wanted to go back to original and what I can read from previous posts the 7809200 is what we could try to flash with.

are you sure? the ecu can be wrote also without uif.... did you checked this in ident? The preheating module will be shutted off also if a worn battery is fitted and if i remember correctly, preheating is involved in regeneration.

Yes the version running in car today is 8506834, checked in INPA.

But if it is a worn battery i should have got a message warning of battery.

All I want to test is to go back to stock because all this happened when we updated to 8506834.

Anyone that has correct zusb with HW 7809000for a N47 Eu4 LL Manual transmission

And this is a FULL list. Look which one is present in your data.

checked how?? in ident or in uif? uif lies, ident no. For the other question, i've already answered in previous posts

message of battery is not mandatory, and after flashing program+data it will take 3 hours to calibrate.
