presuming it is the 3.0 v6 CRD, similar to Jeep Grand Cherokee??
have a look in here …

“Swirl Motor: Failure code is: P2015
Whether your Elephant Hose dripped oil into the Swirl Motor frying the electronics or it actually failed you have nothing to worry about. The swirl motor defaults to wide open regardless of its operation so if it failed in either way it will not affect driveability. In fact other owners who have had it fail like me see no noticeable decrease in low end performance where it was supposed to swirl the air creating a little more power at very low RPM.
The Fix is simply to buy a package (they don’t sell them individually) of 1 watt 4.7k ohm resistors online or from a local electronic parts store. Should cost < $2-$3 in total. Remove the shroud and the intake pipe to get access. See Elephant Hose Mod Above for removal directions. On the drivers side bank of the engine under the turbo inlet you’ll see a plastic clip with 3 wires running to it. Remove the clip from the swirl motor. Take one resistor and insert each end into the two middle wires. DO NOT PLUG IT INTO THE BROWN WIRE. Tape it up with electrical tape and tape it aside to reduce vibration”
I also read somewhere that the reason for the mahoosive bill is labour, both the swirl motor and turbo sit up top nestled in the V, to get at the swirl motor, the turbo has to be removed, to get at the turbo, the transmission has to be removed, you can see where this is going
I think I would be inclined to try the $3 fix first
