Hey guys, I'm Kevin! Got two car issues bugging me —

1. Engine Warning Light Keeps Haunting Me 😵

  • My car’s engine warning light stays on permanently. Even after resetting it with an OBD scanner, it pops back up.
  • Trouble Code: U1140 – "Communication Lost with Active Exhaust Valve 2" (Permanent code from $7E8).
  • Weird Pattern: A buddy had the same issue when his car was new, but the light magically disappeared after driving 2,000-3,000 km (he later installed US-spec taillights and flashed a US tune – related?).
  • My Situation: Already drove 9,000 km, light still won’t peace out. Any fixes to try?
2. Mirror Dimmer 😎

  • Is the "Mirror Dimmer" supposed to activate anti-glare for rearview mirrors?
  • At night, headlights from cars behind are blinding me like crazy – not sure if it’s because:
    • I forgot to enable this function, or
    • My car’s just too low.
Thank you everyone .
