Swirl question I haven't seen asked yet

I tried search but never saw this particular question addressed ....

Once a swirl motor failure occurs and is repaired at the dealership, is the fix permanent or is it possible you could have another failure again down the road?

I ask because the one we just picked up came with the service records and a previous owner had the misfortune of having to deal with the failure.

Thanks in advance!

Resistor mod or GDE tune. Never worry about the swirl motor again

Unless you have the new black intake tube seal and have done an Elephant Hose Mod, I would say no, there is no permanent fix. Even with these mods, the swirl motor is just an electric servo motor that could fail at some time for any number of reasons. To eliminate any problems, you should check out the threads on the swirl motor resistor mod, which will trick the ECU to believe the swirl motor is working, or, as the previous poster implied, get a GDE tune as it disables the swirl motor and prevents getting the CEL. You also gain from increased MPG and power.

its a valid question. I've read posts from owners that have done the costly repair twice, mostly on the UK forums where owners of Chrysler 300c also have the issue. By the way, the same problem also occurs on Mercedes equipped vehicles with the 3.0L CRD engine.

Certainly if you continue with the older style air intake tube and orange air intake tube seal, you risk oil dripping on the swirl motor and having it fail again, however, I have read of multiple swirl motor failures even with the new air intake tube and black air intake tube seal.

I have no concrete evidence, but I am speculating that the swirl flaps inside the intake manifold are so gummed up with EGR soot and oil that eventually the swirl flaps seize and cause the swirl motor to fail.

Some dealers clean or even replace the intake manifold when the swirl motor is replaced. You will have less chance of a subsequent failure if this is done at the same time as the swirl motor. In my opinion, if the dealer cleans or even replaces the intake manifold when the swirl motor is replaced AND you install the "elephant hose mod", you may never have a swirl motor failure.

Thanks everyone, I kind of suspected that it was not permanent, after all what incentive is there for them to fix something that generates so much business right?

So it looks like mod #1 will be the GDE tune... Darn...

Now I just need to decide Eco tune or Hot tune. Maybe I'll just get both and have options

When I took mine to the dealer they had no idea what they were doing. I decided to take it home and fix it myself after they spent almost 3 hours figuring out that the SM was dead. I already knew that and told them what I suspected but it took 3 hours for them to convince themselves. Then their estimate was $1200 to $3500 depending on whether or not they broke the linkage.

I fixed it myself with some encouragement from Tuco.... then several months later I heard about the GDE Tune and dove right in. Now I have a new SM that does nothing...but I'm happy.

I use ECO tune with dpf delete. Love it.
