Hi all,
I am driving Leon ST 1.4 TSI ACT FR and I found a small "problem". I changed to winter tires already so I am not sure if it was with summer tires as well, but now, when I am accelerating (normal acceleration) with full left/right steering I hear quite strange sound, something is roaring in front. I hear it only when accelerating and only on full left/right steering...
And what is completelly strange for my - it looks like I feel some vibrations feedback on my gas pedal. Am I crazy?!?? ?(

I am really not sure if this was happening on summer tires or not, as I drive only 300km on summer tires (car has a week, so I am a newbie).
Is this normal? Is it some kind of "brand new car", some silentblocks are not fitting well yet as it is brand new car?
I put down front wheels already to check if they are mounted correctly (has been done by car-service, not me), but I did not found anything uncommon. It looks mounted correctly. Or is it a sound of new tires?? I really dont know...

Summer tires I had - 225/45 R17, Michelin Primacy, Leon FR typical 17" wheels supplied by Seat.
Winter tires - 205/55 R16 Continental TS850 on 6.5Jx16 ET 46 (as allowed by Seat) Dezent TD dark alloy wheels

Danke

I have visited Seat service.
During test ride technician said that there is really some strange sound he never met/hear before.

Tires and wheels where rejected as source of problem, because when the clutch is pressed, sound dissapears during the ride.
Technician thinks about forces in gearbox or XDS diferencial, but he is not sure. Proposed was to lift up my car and take a look on it from down, will be done at wednesday. But he also thinks there will be nothing to see, nothing to repair and I have to live with that strange sound - until something went totally wrong or 20 years......

Shit. Bought fist new car (previously only used cars) and such an experience..

I went through - it looks like the same problem - it sounds like milling or very similiar. When I heard it first time, I was really crazy I am rubbing something, milling something...

But in corresponding threads there is no answer if it is wrong and have to be serviced or if it is "feature" and we have to live with that..?

Why it is only when accelerating? When I press the clutch, no sound, only rolling wheels...

Car has been lifted and checked in Seat service, I have been in garage next to car so I see it as well.
They did not find anything uncommon, anything broken, etc. No problem at all...

If something comes wrong, then it it will be repaired, nowadays it is a "state of car", normal......

If anybody hase something to add, to tell, please let me know, I will be lucky to solve this "normal" uncommon problem. Btw - Is it a problem or only a sound?
