Light Droning noise at motorway speeds

[Walone]

I looked at the VAG parts catalog again and almost all suspension parts look dependent on the engine type & chassis type, alternatives for the latter being standard & sports variants. The only exception I could see is the coil springs, they are numbered as Lxx where xx going from 1 to 30+. I didn't notice that before. There's no more description but that's where the terrain-dependent differences should be, I guess. I stand corrected, thanks for the information.

I found this section in the workshop manual, showing different running gear for suspension.
