bpeebles is 100000% correct... NEVER EVER EVER EVER TAKE YOUR CAR TO THE STEALER (DEALER) FOR service!!!!!! EVER!
I've had 4, yes 4 TDI's, and just bought my wife a '11 toffee brown Sportwagon. I constantly get 40-45 mpg and I drive like a idiot!!
The most expensive part that failed on my TDI's that I've ever had to replace on any of my TDI's was a $60 N75 valve and some vacuum line ($20). Timing belt changes can be done by YOU, with some mechanical abilities. TDIclub.com has TONS of write ups with TONS of pictures on how to do this YOURSELF! You do need a cam lock tool and another lock tool, but they can be rented for about $75 from friendly people on the TDIclub.com list. The TB kit available at IDparts.com is like $120-$200 for various models of TDI's. Said kits come with EVERYTHING you need to replace all parts while you're that "deep" in the motor.
I'm getting ready to delete the EGR and Diesel Particulate filter in my wifey's TDI as I do not have emissions tests in my area. Hence, no expensive charge, FROM ANYONE for PDF service.
once you get 45MPG AVERAGE, YOU CAN NEVER GO BACK!
The best TDI, and for that matter, all used German cars, are ones with warranty left on them. Not because they aren't good cars, but because they are expensive to repair.
If you won't want to, or don't have the time to be proactive with a used German car out of warranty, or you can't connect with a reliable independent repair shop, or do some DIY yourself, then don't buy a German car out of warranty.
