Handling issues

[mrderv]

Afternoon all

I have some issues with the handling of my B7 Passat. Lately, I am having to apply corrective steering while travelling on Motorways/Dual Carriageways, in what feels like being buffeted by wind. Something that has gotten worse over the past few months.

Not heavy wind either, i'm talking a moderate breeze, and it will feel like the car is being pushed to the left or right in the same way a gale force wind would force a lorry to cross lanes.

Car has covered 155k miles and there is no knocks or bangs from the suspension. What will be the usual suspect components to look at?
