Reading through the concerns and wear history of other tdi owners I am curious about your experiences with the cam lobe issue.
In my 1.8t days (and before) I used to work the balance of cam and gear ratios so that my rpms were always at a point where the least amount of throttle produced the most effective response...not the peak of the rpm range but a combination of rpm and torque. Lugging the engine was not the way to maximum fuel efficiency or performance. I would imagine the same is true for a diesel, even though the rpms for max torque are much lower.
I was told by a VW service tech that the best way to get the best city milage was not to leave the auto trans in Drive, but rather in 4. That keeps the engine out of overdrive and reduces the number of times it must downshift when throttle is applied.
Your thoughts and milage experiences on this driving technique please.
Also, could lugging the engine be a source of cam lobe wear?
