V70 Steering: Intermittent severe steering wheel vibration

[Georgeandkira]

I had a 2002 petrol of about the same mileage, and I can report that on a gentle, downhill curve to the left on a state road, an anachronistic term for motorway, I experienced a wobble which rocked my world.

Visions of shot inner tie rods...outer tie rod ends...control arm bushings....and other fancy stuff, danced through my head.
All are legit concerns.

However, this deep shake didn't appear otherwise. It was easy to compartmentalize...aka ignore.

In the meantime, my fronts wore down and were replaced. The brand and model wouldn't apply to you as you're 'on the other side', but the phenomenon disappeared.
FYI: The new "miracle tires" were Cooper CS-4's; again, N/A to you.

So, I tell you; put on your x-ray glasses and peer into your tires.
It wouldn't be the first time on Planet Earth that bashed/worn tyers caused zizzbo.

Also, worn dampers are the pits. I refreshed mine before "180k miles" and I'd recommend that too.
Your car is at the age for some 'broad brush work'.
