I am working with a 2001 Audi S4  Automatic after flashing the map which is just a stage 1 file this is the error code i get when i scan the auto transmission :
Engine Control Module / Transmission Control Module Incompatible
        P1841 - 35-10 -  -  - Intermittent

car runs fine boosting 17 psi but sometimes when it downshifts or upshift it would get random misfires on all the cyl  cel would flash.   btw this is L box  any ideas ?

Would that cuz the car to misfire ?

car has no boost leak
new coils , plugs ,maf , oxygen sensors , etc


Thanks

yes  any idea ?

Do you know what code i need to input to recode it ?

car has everything almost brand new coils etc . no issue whats so ever. I know it sounds stupid but i  think it  only misfires when it shifts... wierd and is only sometimes so i really think i need to recode the cluster the code comes back right away.
