Hi, my name's Ross, i live in aus and i'm a proud owner of a tt quattro. You might wonder why i'm posting here instead of the tt section or the ttoc( i'm a member there too) but i've been following this for quite a while and i found out there are some very knowledgeable members on here regarding 1.8T. So, here's my dilemmas How do i post screenshot of my logs? I have microsoft works spreadsheet. I've been playing around with my fuel system for about 2 months, i fitted a pressure gauge near the injector rail and i can see about 3.5 bar at idle ( got 4 bar fpr) and goes up to 4.2 bat just before the turbo starts spooling up, after that the pressure drops to 3 bar at 6000 rpm.Is that normal? I replaced the fuel filter couple months ago, today i replaced my fuel pump and neither of them had cured the problem if that's a problem at all. I thought i should see no less that 5.4 bar of fuel pressure but the guy that sold me the pump told me that intank pump don't do over 4 bar. I'm comfused. Thanks.
