Polo AW lane assist + EPC + motor foutmeldingen (incl DTC overzicht)

[Charsom]

Hallo, ik krijg sinds kort tijdens bijna elke rit met mij Polo AW een lane assist foutmelding samen met het EPC lampje dat aangaat. Soms gaat ook het motor lampje branden.

Ik heb de computer uitgelezen (zie onderstaand) maar ik weet niet precies waar ik moet beginnen.

Iemand een idee wat er aan de hand kan zijn?

Ik heb geen verstand van de AW maar als je volgende foutcodes hier opzoekt kom je denk ik al een stuk verder.

01209
02111
00928
02068
16777018

Oh, en haal je VIN-nummer even weg
