[zoly85]

hello

i swap my original golf 4 dashboard 1J5920825C A4-KOMBIINSTR. VDO V09 with a passat dashboard 3B0920822A B5-KOMBIINSTR. VDO V16 because in my original dashboard was failed the half MFA. after the adaptions the new dasboard shows a 20km/h speed delay. ex: real speed is 80km/h he show 60km/h . can you help me to correct that?
