Turbocharger wastegate actuator( code 2565, Circuit high)
kassi posted a topic in Audi A3 (8V) Forum
Hello everyone. I got into some trouble after buying a used 50000 km Audi A3 8v. Just after a week i got this EPC and Engine check light when i was driving. EPC light goes off every night and when i go to work again next morning it shows up again. ON IDLE: Turbocharger actuator voltage : 3.68 -3.71V Turbocharger wastegate position: 0 -3% Turbocharger was changed recently by the previous owner. I dont know if they changed the actuator or not but it looks good in condition no rust. I recorded couple of Actuator parameters with OBD II Scanner. Driving on highway i let the throttle go (no throttle) around 90km/h suddenly the EPC and Engine Check Light came on(attaching video with it). And the actuator signal voltage went to 4.99v which actually stays at around 3.7v without epc and engine light. After EPC light (seems like actuator position sensor failure) the actuator stays at 0% and i get Poor acceleration. Help would be really appreciated. Screen_Recording_20230621_232903_1.mp4
