DV is the little blck thing that controls the air flow/pressure of your Ko3 turbo in the 1.8T engine. If you want can come to our meet tonight and maybe we can find out what, otherwise its best to go to the garage. Next month I might buy the check ehine tool then I can check my own errors, for now we can just see if anything is wrong, lol, good luck

check engine light一直亮着是怎么回事啊?
发动机状态好好的~(里面每样需要加液体的都加的刚刚好,发动机温度也正常,运转也正常)
到家了把前盖打开,听到引擎底部有很小的爆裂的声音,真的很小,有点像跳跳糖放在口里的感觉....
不知道正常不? 郁闷....

check engine light一直亮着是怎么回事啊? It could be that the oxygen sensor does not function properly. Got to take your car to a garage to check it up.

引擎底部有很小的爆裂的声音, that is normal in a cold or cool day. That "爆裂的声音" is from the exaust pipe or its metal shields when they are cooled down drastically. No worries.

汽油中含有杂质（比如水分过多）以及点火不良都会产生类似的现象～
