Update....I decided to just go for it and change out the filter. I removed the torx screws, removed the filter..housing and diesel looked pristine only maybe 3 tiny dirt particules or something of that sort, even the filter looked super clean? I buy my oil oil filters and fuel filters @ Noyes VW in New Hampshire as there is no tax no shipping ect. and the price of the Castrol full syn is only 9.09 a qt. which is pretty good! but the only kicker is the damn fuel filter is like 34.00!!!! which i think is way too expensive!! Any body have a good place to get the fuel filters?? Ok back to the filter change....I added in fresh diesel..(too much) pushed the filter on pushed her back in and made a complete mess overflowing diesel everywhere...LOL...I have a siphon with a check valve and took some out then set her back in and installed the screws. I soaked up the diesel with PIG blankets and flushed her out real good with the hose. Turned the key and she fired up instantly. Zero issues. Not as bad as I thought. I will eventually get the cables and learn the VCDS system. Thanks for the replies!
