2010 328 ix - engine sound on highway
I just purchased a used 328ix and I LOVE this car. There is one issue - but I don't know if it is a "problem" or just normal for this vehicle.
Below 80 km an hour the engine is quiet - perfect. On the highway, at 80 and above, the engine is not quiet. I would describe similar to when you have a manual transmission, right before you gear up (when the RPMs go higher and you know you need to gear up).
So far the dealer says they aren't hearing anything, but I'm not sure if this is really normal.
Thanks for your feedback!
