My name is Tim and I came across this site while troubleshooting a turbo issue with my fiance's Jetta. There is so much good information here it would be silly of me not to register. I work in the IT Security field but have always done all the maintenance on my vehicles. I used to race motorcycles as well. Anyway, I have very limited knowledge on turbo diesel motors. If you have any questions about motorcycles, fighting fires, or computers, feel free to send me a personal message and I'll be happy to address it.
