2001 gti Engine light blues

[quiksilva]

Hi anybody, I am bumming a bit as I just spent good $ at the dealership gettin rid of engine lights and 2mos. later ...another engine light??? The problem is that I don't trust the dealership because service guy was trying to sell me a timing chain(separate issue) after gettin rid of the light...saying it was overdo and a local mechanic said it's not to be replaced and they were trying to rip me??? I have 90+ thousand miles on her and besides the aggrivating lights I love my car(still runs like new) and don't know what to do??? I guess I'm asking if lights are normal for the mileage or is it a freak defect? Yo Y'all please advise. Thanks
