Hi all,
I just got warning light on the dash 'gearbox malfunction you can continue drive (limited functionality)' Audi A6 2016 2L TDI S-tronic automatic gearbox. It happened few weeks after gearbox oil service, fault disappear after turning off engine and starting again, works as normal for few weeks then happens again, and again more often, usually when its cold. Brought it to the Gearbox garage they scanned and found 'P187A engagement not successful' its says need furder investigation, open up gearbox and to look inside would cost about about 2K euro . Does anyone have this situation ? what was wrong with it ? how did you fix it up? I'm looking any recommendations and advises. Thank you
