What's wrong, in plain English
BMW is recalling certain M2 Coupe and M4 Coupe vehicles because some fuel injectors may have been built without a small damping part that is meant to reduce vibration. Without that part, vibration increases at the point where the fuel line connects to the fuel rail. Over time, this extra vibration can wear down and damage that connection.
What you should do
2. Contact a BMW dealer, or call BMW customer service at 1-800-525-7417.
3. Dealers will inspect the fuel injectors and replace parts if needed, free of charge.
