Good evening I have a 2016 audi Q5 2.0 tdi cnh engine code in the workshop which does not have left turn signals

in the comfort control unit diagnosis I have the following error code 02988 left and right-hand traffic permanent active gear shifting

with the diagnosis I can control the individual 6 front and side lamps, with the 4 arrow button everything works normally

Before replacing or disassembling the light switch I wanted to know if you have any information

Thank you in advance andrea
