The blower-regulator wiring harness in your 128i, 135i, or 135is Coupe or Convertible is a set of wires and connectors that control the air conditioning and heating system. In some 2008-2012 models, these wires can overheat.
Risk if Unfixed
If the wiring overheats, it could melt and cause a fire, even when you're not inside the vehicle. This is a serious risk, and you should take it seriously.
Free Fix
Your BMW dealer will inspect the wiring harness and replace it with a new, safer one at no cost to you. They'll contact you when the repair is ready, and you should schedule it as soon as possible.
