Think if nothing else will make a connector with instructions and soldered to spades and kept in the glove box for when it does happen.
yup, would be good to have a resistor sitting in the glove box with whatever other hand tools are needed to do the install just in case of a failure, you can make it home.

What are the disadvantages to doing this? I'm sure the swirl motor serves a purpose.

So do I even need the swirl motor and the swirl flaps if I put the resistor in and if I put the resistor in can I take the motor and flaps out

I've had mine attached for a week, not too many miles yet.
Going on a 3,000 mile trip next week.

Here's one on my WK. I used a spade (fork) connector and cut off one side of the fork and soldered the resistor to the connectors. Then I taped it and put a tie wrap on it to prevent the tape from coming loose due to the engine temps.

How would qualify your performance and eco with the resistor added on top of the tune ?

Well, our 2008 GC is three months out of warranty and while my wife was driving to work, we got the dreaded P2015 code and the jeep is in limp mode. I have the new black seal as well as the Racor filter but after removing the turbo inlet duct, I see that there was still some oil leaking above the swirl motor. I'm going to buy the resistor tomorrow and hopefully it will work and get the jeep operational again.

Did mine today after losing major power coming up to the house. So far, runs great, no CEL. I have the In Motion tune as well and do not notice any difference in power with the resistor mod.

Came across this document on how the Mercedes swirl motor functions. The Mercedes forum I found this on indicates that there should be no noticable difference in performance on whether the swirl flaps are open or closed. The Mercedes forum also indicated that using the resistor will fool the ecu into thinking that the motor is still connected. Since the swirl motor is disconnected, no fault codes can be generated so all should work as expected.

Installed the 1 watt, 4.7K ohm resistor, cleared the fault code and the jeep is back up and running. Will be talking to the dealership to see if they will consider doing a repair.

I put 700 miles on it today, passed 10 vehicles, after a road works stoppage, at a sustained 100 mph and noticed no difference. Rough calc of mpg is same as before. Will put a calculator to it later. It did a regen at the usual 750 miles period.

3 days with the resistor and still no issues. My swirl motor was needing replacement when this mod was done.

Just put 2,600 miles on it with the first two stops exactly the same as a month pre-resistor ago. Last month I didn't use the a/c, this trip it was on all the time. Drove just as hard and got 1 mpg better over 800 miles, so not statistically better, but definitely not worse. And it does seem to have better get up & go. Don't know why, don't care!
