[Vwdiesel] Injection pump timing?

Loren, sounds to me like the Passat has an issue with one of its temp
sensors.
When you go into Basic Settings, it disables the dynamic timing adjustment
and you're running the "mechanical" timing, i.e. it's injecting according
to how it's physically timed by the setting of the pulley/belt.
If it's running better *without* the ECU "fixing" the timing, the ECU must
think it's much warmer than it really is (either fuel, coolant or intake
air temp).
It's been a while since I used my VagCom but IIRC the adaptation problem
means you're not logged in to the ECU correctly?
