Just to add further info to the thread...

The pink circle in the photo above is the crank pulley for the auxillary belt.

Yeah, I know that's also a damper but the part alone costs £250 so nothing like this mysterious $120 to fix the issue on overrun. I had to replace mine when the aux belt snapped and the whole job was £500. (Other than a service, I've yet to have any work done that doesn't cost at least £500! A single rear damper was £720 fitted, and none of this is at a dealership.)

For $120 it must be something to do with the fuel line and I can't see how that will sort the revs on overrun. To my mind its got to be something to do with the gearbox software...
