EPC melding 1.8 TFSI rijdt niet anders

[Garra432]

Goedemiddag,

Mijn A5 1.8 TFSI uit 2012 heeft tijdens het optrekken soms ineens dat het EPC lampje aan gaat en aan blijft. Er is dan geen verschil te merken in de karakteristiek van de motor.. Hij rijdt hetzelfde als voor de EPC melding. Tijdens dat EPC weergegeven wordt kan ik de tractie control niet uit zetten. De tractie control flashed even maar gaat gelijk weer aan. (Mijn gedachte was dat de EPC misschien beïnvloed kon worden door de tractie control, maar toen kwam ik erachter dat dit dus gebeurd). Ik heb laatst wel de luchtfilter, oliefilter en olie verwisseld. Misschien dat de MAF/MAP sensor per ongeluk niet goed zit deze symptomen kan veroorzaken?


Ik heb hem uitgelezen met VCDS:

Hebben jullie een idee wat het kan zijn?

[tom]

Even wissen, gaan rijden en dan opnieuw uitlezen.

Na het wissen en een tijdje rijden kreeg ik weer de EPC melding.

Ik heb de connector en kabel bekeken en deze leken goed.

Na de code gewist te hebben heb ik een tijdje niet meer een EPC melding gehad.

Auto uit doen en starten verhelpt het probleem, maar het blijft onvoorspelbaar wanneer de EPC melding opkomt. Het enige is dat het rond de 2k/3k toeren gebeurt als het gebeurt.

Ik heb hetzelfde echter met foutcode P2563. Dit blijkt de turbo klep actuator te zijn die zijn gewenste stand niet behaald. Dit kan een een defect in de klep zijn of een vervuilde turbo. Ik ga nu de turbo reinigen met een turbo cleaner. Als dit niet helpt dat zal ik de actuator vervangen.
Bij mij is het vooral met koude motor waardoor mijn vermoede van een vervuilde turbo toe neemt. Ik verwacht met een hete turbo en oliesmering alles wat soepeler loopt met de klep. Mocht dit het oplossen laat ik het weten.
