I have read everything on this forum about this problem and am now more confused than I was before I started. I bought this car less than 2 weeks ago (already regretting it) My car has 77k on it. I put less than 300 miles on it before I felt a loss of power driving down the freeway with no CEL(wouldn't keep speed going up hill, and took forever to get up to speed). After re starting the car I had return of power for about a min or 2. After cooling off it went another 200 miles or so before doing it again. Now today it started throwing a CEL reading engine overboost condition. I originaly read and thought mabe the MAF but after further reading here I am not too sure. I am not super mechanicaly inclined and I don't know where to even start. The VW dealer here is a bunch of crooks and I don't want to have to take it there. I may try and fix it and sell it before I run into more problems (don't want to b/c I do like the car) Help please!!!
