18 droning months with an E70

[richardl]

Awful tyre noise (like a droning propeller plane) and dealer who sympathises but BMW technical say "Normal!" Between 20mph and 70 mph the tyres resonate through to the cabin, completely spoiling what is otherwise a fine car. I am used to tyre and transmission noise on 4 x 4's but this is so unpleasant. At 18,000 miles I will soon be ready for a new set but BMW will not commit to advising what will be quieter. Maybe the answer is non run-flats but I prefer to stay with specified tyres if possible. The original tyres are Bridgestone Dueler F: 255/50 R19, R: 285/45 R19. Anyone out there had experience with changing between different makes of run-flats?

Frequently blocked filters on screen washers can be relieved with an air line but dealer says front wing must be removed to clean thoroughly. What causes the blockage?

Taking UK car to Europe requires headlamps to dip right instead of left. Anyone tried reaching the back of the headlamp units to move the levers? It needs a mirror to see the levers then a child sitting on the engine to reach inside the wing! Is there an easier way for someone with average size hands to perform this seemingly simple task?

Very grateful for any advice, particularly with choice of tyres.
