I will add that I nearly sunk my 2007 GTI SE 155 in 2001. I frantically called around for a shop to help me and nobody could or would. But one experienced shop told me how to effectively remove water from the air box, throttle body, and intake manifold using a powerful wet/dry shop vacuum, without taking everything apart like the shop manual directs. As a nearly 40 year automotive service professional, I don’t disregard shop manuals and manufacturer instruction. But there are sometimes more than one way to accomplish something. Let’s just say that I resurrected that ski using the advice I was given and still ride it - just rode it a couple hours last Saturday and it has 350 hours on it now.
If interested, I put a pretty clear description of what I did in this forum in Feb/March 2001 if you want to try it and you are a little mechanically inclined.
