Hey guys,

There's a loud high-pitched vibration noise I'm hearing from the ?exhaust on cold starts. I've had my car for 2 months and it's done over 3,500km (bought as demo).

I took it to the dealer this week. The service advisor was quite shocked and had never heard it before. It picked it up yesterday with no noise, but it has returned this morning.

This is the job description record: "Carry out start up of the vehicle. No noise present at time of testing. The vehicle had been driven and was warm. Need to perform cold start. Carry out cold start and confirmed noise was coming from the vehicle. Lift vehicle up on the hoist and found the exhaust heat shields loose knocking on exhaust. Carry out refitment of the exhaust shields. Test multiple times all okay."

I've found very few comments on Bimmerpost regarding the same issue, but the thread was more about squeaking noises from the trunk seals.

Anyone else experiencing this? Appreciate your help.

Back to the dealership I go...
