Hello all!
I have a 2011 GTI 6 speed with 183K miles on it. It has several standard mods with an APR stage 1 tune. I typically only use Shell gas, but I used ARCO the other night. After filling up my car, about a mile or two down the road the car started to get really rough like it was misfiring. The check engine light began flashing. I pulled over and changed my tune back to stock and tried to start it again. The car then started rough, and this time I could smell gas. I called up a tow truck to get the rest of the way home. When the driver showed up, he asked if I could drive the car up the ramp. This time, the car wouldn't start. After he took a minute looking around the engine bay, he jumped in and was able to start the car by holding the gas pedal down and cranking the engine. He said the engine was flooded.
The next day, I had the car checked with an AutoZone OBD2 scanner and no fault codes came up despite a check engine light. I decided to buy new plugs since I was due anyway. When I pulled the old plugs, there was black soot on all of them. I put the new plugs in and started up the car. Tah-Dah! Started up and purred perfectly. For about 20 seconds. Then it began jerking again and the check engine light began flashing, and gas could be smelled near the exhaust. I pulled the plugs and they were covered in black soot again, and there was clearly a smell of gas after pulling each plug. Now I was fairly worried, so I called up a buddy of mine and had him bring over his VAGCOM cable...

So the first thing we did was pull out a burned up 5A fuse and replaced it. This removed the Aux coolant pump error. I also swapped the PCV(old spare in questionable condition) and coil packs(R8 to OM) just to rule them out, and they seemed fine. I hooked up my air compressor to my turbo inlet and checked for a boost leak. While I couldn't find a leak, and it's been awhile since I tested for boost leaks, I had a feeling that air was escaping the system too quickly. Most of the air was gone in about 20 or so seconds. I also realized that by checking for a boost leak, I believe I pushed gas into my oil, although it's possible some could have already been there.
SO here I am. My though process is that it could be something with the intake manifold, throttle body, carbon build up, or the ECU. I think the ECU is reading lean and dumping gas, but I really don't know. It may also be the turbo, which wouldn't be surprising either. I was hoping for some insight before I go ripping apart the intake manifold. Thanks in advance!
