증상

2019 인피니티 QX50에서 날씨가 더운 날씨에 가속 시 동력 손실 발생. 터보가 제대로 작동하지 않는 것처럼 느껴짐. 체크 엔진 램프는 없음. 전반적인 성능 저하 발생. 열 영향(heat soak) 또는 터보/엔진 관련 알려진 문제일 가능성.

처리 내용

고온 날씨에서 공기 밀도 감소로 인해 터보차저 유무와 관계없이 모든 내연기관에서 동력 손실 발생 가능 — 터보차저 불량과 무관할 수 있음. 터보차저 문제가 있다면 주로 윤활 문제일 가능성. 다음 항목 확인: (1) 엔진오일을 주행거리와 경과 시간 기준으로 정기 교환했는지 확인, (2) 정품 전합성유 5W-30 규격 사용 여부 확인, (3) 오일량이 디프스틱 정규 수준인지 확인, (4) 프리미엄 휘발유(고옥탄가 연료) 사용 여부 확인.

I wanted; Clubsport pack, PDK, dual zone climate, either shark or gentian blue, yellow sticking, leather dash, sports chrono, rear camera, FPSH and Porsche warranty. Everything that came up matching that was either over budget, sold before it was advertised or sold the day it was advertised. I even lost out on a car to Jay Kay, cool story, bro. I left my details and requirements with the likes of RPM and JZM in the hope of a call before a car was advertised. There was some time pressure. I naively booked a tra
