每次省190块。上次是engine light亮了，结果诊断出来油箱盖没拧紧，果真如此。
这次是headlight没关导致电池耗尽，不能点火，headlight却关不掉。再一次搞定
Your Car Does Not Use Headlight Relays
Unlike older cars, the XXX uses solid-state electronics (no standalone headlight relays). That means:
You won’t find a headlight relay in the under-hood fuse box.
Removing fuses likely won’t stop the lights — only disconnecting the battery will.
Summary Action Plan
Step Action
1 Disconnect battery for 5–10 min
2 Recharge or jump the battery
3 Restart car and test headlight switch
4 If issue persists, scan BCM with VCDS or OBDeleven
5 If still stuck, BCM may need reprogramming or replacement
