F30 328i scraping noise

armanm · 07-07-2013, 09:50 PM

So today I noticed this weird scraping noise each time I come off from a stop and accelerate for about 2-3 seconds and let go. Its hard to hear at speeds above 25 the weird thing is its repetitive and not something that happens once or twice. Each time I tested it out I got the same result. Its a scraping noise that seems to be coming from the backside of the car almost feels as if it is from the exhaust itself.

Anyone felt something similar? Any thoughts?

I had a similar scraping or grinding noise when accelerating AND turning right. Took the car to the dealer, it turned out to be the exhaust system hitting the gearbox. After adjusting and securing the exhaust the noise stopped.

I have that in stop start traffic. It is a faulty diverter flap in the exhaust. They are getting a replacement from germany and it arrives in 3 weeks.

I believe it has no detrimental affect on the car.
