난이도 & 준비물
증상
1998년식 아우디 A4 (20만 마일 이상 주행)에서 공회전 시 매우 심한 라틀링음 발생. 엔진이 한동안 작동한 후 주로 발생하며, 2000rpm 이상 회전 시 음이 사라지고 주행 중에는 조용함. 간헐적으로 공회전 중 라틀링이 지속되면 오일 경고등(압력 경고등)이 깜박이고 소리가 나지만 주행하면 사라짐 (오일량은 충분함).
처리 내용
오일 경고등이 점등되는 이유는 공회전 시 엔진 오일 압력이 오일 압력 스위치 작동 압력까지 저하되기 때문임 (오일량 경고등이 아닌 압력 경고등). 엔진음과 함께 발생하므로 오일 압력 문제로 진단됨. 신뢰할 수 있는 오일 압력 게이지를 사용하여 정밀 진단 필요 - 공회전 시 오일 압력이 비정상적으로 낮을 것으로 예상됨. 일반적으로는 엔진 마모의 신호이지만, 오일 점도가 너무 낮은 경우일 수도 있음. 어느 쪽이든 현재의 라틀링음으로 인해 이미 엔진에 손상이 발생했을 수 있으므로 전문 정비사의 엔진 점검 필요.

This is a thread about my first car which I've owned since 2003, it started life as a 1.3 8v Polo GT, all 75bhp and 800kg. Chapter 1 - The Early YearsI don t have many photos of my car standard, partly because it didn t spend much of its life in this state. However, there was a brief period I was content with cleaning it, polishing it and adding a few shiny dress parts. It looked like this:If ever there was a car that didn't have a clue what the next 23 years held for it... Shortly after passing my test, I bought a Wizards of Nos nitrous kit, and jetted it for about 80bhp and made my way down

insane build, bravo, looking forward to seeing this at a trackday at some point!

새 에어컨 증발기를 구입했는데 일부 핀이 구부러져 있습니다. 통관 검사 중에 종이 커터로 패키지가 손상되어 핀이 약간 눌리고 잘린 것으로 보입니다. 반품해야 할까요, 새 것을 받아야 할까요?
