Is the engine coolant temperature sensor responsible for the rough idle in my BMW 5 Series?

I've noticed a rough idle in my BMW 5 Series and I'm wondering if the engine coolant temperature sensor could be the culprit. What are some other signs of a faulty sensor and how can I fix it?

Yes, a faulty engine coolant temperature sensor can cause a rough idle in your BMW 5 Series. It may also result in poor fuel efficiency and difficulty starting the engine.

Another symptom of a faulty engine coolant temperature sensor is an illuminated check engine light. I recommend getting the sensor checked and replaced if necessary.
