I recently had the camshaft replaced in my 2006 Jetta TDI (245,000 km).

I keep a fairly close eye on fuel economy and after a couple of tanks, it definitely seem like I'm getting 5 to 10% less mileage per tank of diesel.

I barely understand what a camshaft does, and what replacement entails (though I recall them saying that "lifters" were replaced along with the camshaft). Anyway, unless it's my imagination, I now occasionally experience engine "hiccups" and hesitations when starting at lights and stops signs etc.

Is there something that could be out of adjustment after a camshaft replacement? I just don't want to take it back and have them say, "Nope, definitely not anything we did".

Any thoughts? Thanks in advance.

One possibility is that the flywheel could be going bad and it's unrelated. Is it a DSG?

Another is that they did not set the torsion value after doing the camshaft. It should be more or less on because of the lock pin but it should at least be checked. Here is how to check / adjust it: http://www.myturbodiesel.com/1000q/multi/PD-adjust-Idle-TDI.htm
