New D300 is developing strange noises in the interior when travelling at around 180/190+ kph. The noise almost sounds like "interference" from the sound system, i.e. it's an electronic/electrical noise rather than mechanical. I only have the standard differential (the manual specifies that anything above 190 kph is not recommended if you have a rear diff). Perhaps it just doesn't like German motorways.

Anyone else?

190kph.... 118mph....! speed limit in the UK is 70mph :-) Not surprised you're getting strange noises. These cars have the aerodynamics of a brick, you're braver than

Old tyres or differential, i had to replace differential cause of whining noise at high-speed
