Since I've bought this jeep I was wondering when the swirl motor problem would occur with me, and since then I was looking for a spare swirl motor over the internet.
Well, last friday swirl motor rested in peace.
After a long and slow driving weekend, I've installed the resistor today.
Well, till now, the resistor saved me about 2,500 brazilian bucks.
I bought 10 resistors and spent 0,20 cents each.
Car is running ok. Tomorrow I'll travel about 800km and I'll see how it will be.

Roughly 1 month later and the resistor mod is still working perfectly.

Just thought about something here... I think the resistor mod can also be applied to the EGR valve (rear right back corner of the engine when facing). Not sure how many ohms but it can surely be measures. Only probleme now is how to keep open the EGR throtle valve after all...

Every actuators can be bypassed with a resistor mod... Conditional to by a 3 wires actuator (ground, voltage suply and pwm signal)

Some 300C guy's have been trying to do the resistor mod to the egr, but are getting a DTC for low egr flow. It runs fine, but you have a check engine light. You can read about it on the 300C forum. I want to do this resistor mod to the throttle valve so that restriction can be removed. Just need some time to weld up a throttle valve replacement pipe.

... Or even better, I think EGR disabling can also be acheived by fooling the O2 sensor ... Simulating exhaust gaz are to low in O2 (to rich then it shouldl be) this way the ECU will request more O2 in the intake (closing egr valve and opening trottle valve)

Could you please post another picture so I can have an idea where I could find the swirl connector? Just to be sure how many items I would have to remove before getting to that connector.

I have ~80.000KM with my jeep and all is good until now but this swirl motor replacement is scarring me !!! so I'm very excited to the idea of using a simple resistor bypass.

Thanks.

In that picture it looks like he has remove the main engine plastic cover, then he has removed the cold-air intake tube that runs from the air-filter to the turbo, and that is it. Just the (2) parts.

You can see the connector inbetween the fuel filter and the turbo in the picture.

Thanks, that looks pretty easy.

Can this modification be done as preventative medicine? My CRD seems to be running properly as of now but if I can eliminate the possibility of a failure simply my wiring in the resistor I'd like to do so.

Also just so I understand the procedure is this:

Unplug
Insert resistor and fasten
Leave unplugged
Enjoy Jeep

Is the resistor to prevent a check engine light only or does it help prevent the limp mode? If it just the prevents the CEL has anyone driven around with just unplugging the motor and no resistor?

If I am not mistaken, (can't remember if this forum or another), there was mention that you could just unplug the swirl motor and it would go to full open. The Jeep would not be in limp mod, but would would still have a CEL.

That's what I was thinking, so technically the resistor is a Sim like on DPF deletes for the cummins in order to "fool" the computer into thinking the parts are still attached and working properly.


Sweet! I might have to pick up some resistors this weekend

Yes, this mod can be done as preventative maintenance. My swirl motor was working properly when I installed the resistor. You are correct in your process. The Jeep will go into limp mode if left unplugged with no resistor.

Anyone have an extra resistor I can buy? Seems you can only buy it in bulk and only need one itself. I'd like to have this just in case as I use it to tow at least 2x a month.

Would there be any interest in having a plug made for this? I have a buddy that makes SIMS for the EGR and DPF deletes on the 6.7 cummins. I can see if he will make plugs so that you essentially "cap" the harness end of things rather than just sticking the resistor in and taping it up.
