S5 Fc fuel cut problem

Hey guys hate to pester everyone again. But The last 2 months or so My FC gets a fuel cut when I take left turns at deacent speeds. I replaced the fuel filter recently in attempt to maybe solve a problem. That didnt work. I also only carry around a quarter tank to a half a tank. So i was thinking maybe the gas just being shfited around in the tank..But i dont really know. It doesnt happen on right hand turns Just on LEFT turns. Any ideas?

The section FAQ suggests the problem could be a dirty sock or rusted out baffles. Definitely change out the filter sock in the fuel tank.

You should have more fuel in your tank when cornering hard. The pump is on the left side of the tank so when you make a left turn all the fuel goes to the right side of the tank and the pickup is therefore dry. This is very bad as it's not the injectors not fireing but a fuel pressure drop instead, which means the car will have a few lean cycles before it seems like a fuel cut. Keep doing this and you will blow your engine, espicially if it is a turbo.
