  1. Perhaps you can use a multimeter to discover which one shows a resistance to ground that would jive for a thermresistor. If you know where the footwell sensor is then maybe blast with hairdryer and see which wires changes?

    Measure the one on the bumper as the outside temp sensor to get an idea for the range?

    Did you go through the 2000 HVAC Schematic and find all other sensors except the footwell one?

  2. The more I think about it, the timing should not have "jumped" unless the mechanic did NOT lock the cams which is a very simple process. Armed with the error codes it could have just been a simple replacement of the variocam plus actuators. (two on each bank ~$150)

    Actually it is very likely the mechanic did lock the cams but was not familiar with the 02+ special process for replacing the tensioners and setting timing of the bank. You cannot just lock at TDC and pull + replace the tensioner and expect to have proper timing. You have to rotate to 60* prior to the TDC (OF THAT BANK!) when you are placing the tensioner. Then rotate to TDC to remove "slack" (created by the movement of the variocam plus vanes) from the chain as you are setting timing. Otherwise your variocam plus "mechanism" will not have the proper angle. (sorry if not making sense)

    Again much easier on 99-01.

  3. Resetting the timing on the 02+ engines is much more difficult that the earlier ones. Unless you want to fork out $1k just for the tools then get it towed to a mechanic. Sounds like the mechanic you used caused more harm than good. It is highly unlikely that the variocam plus mechanism wore out (guessing that's where the $7k figure came from). I am shocked that you didnt at least get error codes from the initial issue.
