    It really could be anything right now.... DI engines are kind of known to carbon cake the intake valves. I have 3-4 DI cars here and have never had the carbon problem that I'm aware of. I guess we are offering ideas on what it could be. Pretty sure you will need a scan tool to see any engine data....one of the parameters would show the fuel pressure. No way to hook up a gauge on a high pressure system. Pretty sure you will not find a fuel filter.
