I have owned my 2006 Jetta TDI for a few months now and have been a regular visitor to this site during that time. The myriad of faqs have been really helpful and although I've only done routine maint on my vehicle thus far, I am going to start really getting my hands dirty in the engine compartment.
My mpgs have been a little low ever (like mid 30s) since I got the thing and I will be checking the MAF, cleaning the intake and EGR, and (if i can solicit the assistance of my VCDS wielding friend) turning that EGR thingy off. Of course, most of this wouldn't be possible to me if I didn't know about this site so :bowdown and thank ye kindly.
