Hey Guys, new to forum wanted to get input on my new '04 TDI Wagon.
I recently was gifted a wagon from my father he upgraded to a '17 golf wagon and wanted to keep the TDI in the family. I picked the car up in Buffalo, New York and drove it back to Richmond, Va. About a 500 mile trip. The wagon has stage 1.5 Malone tuning.
I took it to the shop in Richmond, where I had been having my '99.5 VW Jetta AEG serviced, to get the Va State inspection.
Was told that I had to get the intercooler replaced and the valve cover was split - $1500 repair. He said he replaced the intercooler with a Behr intercooler which is better than the stock one, and will never break, as that is a problem with the stock PD TDI intercoolers.
Since then I have noticed a significant decrease in mpg. Driving back from Buffalo, I calcualted 47 mpg (I guess with the bad interooler and cracked head gasket). Since having that work done I am getting about 34 mpg. Obviously there is a bit more city driving and sitting at stop lights, but that seems like a huge decrease. I checked with my dad and he said that he routinely got 40s city and 50s highway (which was confirmed by my buffalo trip).
When I checked back in with my mechanic he said that he had a hard time believing that a chipped diesel would get that type of gas mileage (40-50 mpg).

Thanks Guys!
