Q. About regen: How would I know how often the car is going through a regen cycle? I have heard the fans running full blast, after shutting the car off, 2 or 3 times. However, my son and wife primarily drive the car, so I don't really know.
A. Regen is hard to impossible to detect while you are driving. It is very noticeable (fans, as described above) when the engine is shut off.
Q. Lastly, the oil consumption seems to have gone down considerably over the last thousand miles or so. At this point, I think I'll do an oil change and track the consumption a bit more closely. Would anyone suggest I actually take the car into my local dealer for the oil change and to start an oil consumption test?
A. No, don't take it to a dealer yet. Do the oil change and closely track and document the consumption. A quart over 2000 miles (per post # 30) is probably not going to stimulate VW to do anything at all. If the car was mine I would track consumption, keep it topped up, use only approved 507 oil (just in case something more serious occurs), and motor on.
