Fuel filter Wix or OEM Volkswagen

-fuel filter -fuel lines (ss braided are great)

Try changing out the fuel filter, sounds like you have a lot of water in it. Wen the filter fills up with water, the engine pulls gas off the top (gas is lighter than water) and regularly gets a slug of water along with it which can cause a misfire at startup and on the road too.

Just finished my 5K service. My dealer had never stocked the VW 507 oil! Special order for me. Anyway, your 2007 has the BWF engine where the fuel filter sits beside the motor on the driver side. in the middle of the four hoses is a torx head screw. Remove this and pump out (or syringe out as I did) about 100cc. Mine was perfectly clean.

May not hurt to change the fuel filter too

I also bought a new fuel filter for it and will be 100% sure to prime it well before installation.
