yes they can.The tune i got causes your egr to close most of the time which eliminates your swirl motor issues. Swirl motor issues do not happen in europe because the diesel fuel is better, keeping your egr valve closed will help your swirl valve. check with http://www.jrautoelectronics.ca/

green tune is not the only game in town!

How does fuel quality have an issue with the swirl motor? Carbon deposits can have an issue with the swirl valves, but it usually fails from the leaky seal at the turbo.
I do not disagree with with egr issues. I have mine blocked and disabled for quite sometime. EGR is one of worst things for a diesel engine.
How is the JR tune? Any performance data? There website doesn't provide much info.

I get Liqui Moly 5w-30 off eBay in 20 liter from a seller in OH. It is what they normally use in Europe on diesels and it is full synthetic. That gives me 2 oil changes and comes out to $132 with shipping. I also found MANN oil filters from thepartsbin for $15 each (half what you pay at the dealer) - part #: W0133-1789376 for '07-'09 Dodge Sprinter 3500.

I just spoke to Keith and placed my order for the Green Diesel program. It seems the pricing structure has changed recently. Now there is only one option for $695 that includes the purchase of the programming tool. I was going to buy the programmer, anyway, so this represents a $50 decrease in the price. The total came to $700.35 with Priority Mail shipping to Maryland.

I'm looking forward to some extra power and MPGs on our summer Airstream adventure to the Great Smoky Mountains National Park. The main reason for the GDE purchase is the swirl motor bypass. I don't want the GC going into "limp mode" on the interstate in the mountains of North Carolina with my family in the Jeep while pulling a 5000 lbs. trailer.

Hi, I have been following this thread with some interest as I have had swirl motor issues recently with my 2006 Grand Cherokee .
The ETC warning light came on a few weeks ago and it went into limp-home mode, and the dealer told me it was code P1270 and had to replace the swirl motor (costing about 600including labour). Two weeks later I've got the same problem again but it happens one day, and works fine the next! The dealer is saying it is a different code this time - P0046, and I need to replace the whole Turbo at a cost of 3600 for a new one, or 1000 to recondition the old one! Would the GDE tune stop these swirl motor issues? And is it available to send to England?

Yes the tune takes the swirl motor out of the picture...plus you get more hp and torque and better fuel economy.

Contact Keith at GDE about getting the tune to England.

We ship tunes to England no problem and the tune will eliminate the swirl issue and code. I am more concerned with the P0046 code. I have seen this code on several vehicles now and it is an internal problem with the turbo REA (black box on turbo that controls vane position). It stems from overheating the device over prolonged time. If you can take pictures of the part numbers on the REA unit, I will investigate sourcing it. No sense changing the entire turbo assembly for a relatively cheap part. The underhood temps of the WK CRD must be very high and the packaging should have been engineered better to reduce the heat the REA is exposed to.

Thanks scootr and GDE.
I'm still driving the Jeep to work every day(carefully) so it will have to wait until the weekend but then I will see if I can get to the REA to get some part numbers.
Is replacing the REA something that i could do myself or does it involve removing the whole turbo?
I'm not experienced enough for a job like that just yet.

GDE, I just saw one of your other posts (number18 on "3.0 CRD electronic throttle control error", and there you say:
"P0046 is most likely causing the low boost code P0299. P0046 signals something internally wrong with the 'rotatry electric actuator' that controls the vane position on the turbocharger. The is the black box mounted on the turbo. It may be the internal circuit has overheated and is not moving correctly or keeping the vanes in the proper position based on speed/load.
Clearing the codes to see what comes back is generally good practice, most of the other codes seem like random errors and would not cause the low power issue. After clearing, does the Jeep perform well again? See if it works well with a cold engine and then with hot engine. If problem re-occurs then the turbo will need maintenance. Unfortunately, if that is the case the turbo is sold as an assembly (cannot replace just the REA)."

But in this post you said that:
"If you can take pictures of the part numbers on the REA unit, I will investigate sourcing it. No sense changing the entire turbo assembly for a relatively cheap part"

I'm confused now whether the REA can be replaced separately from the turbo or not?
Thanks in advance for any clarification you can offer.

Through Chrysler the turbo is sold as an assembly, so the REA cannot be purchased separately as the moment. If I knew the REA part number, then I could contact Bosch directly to see if the REA can be ordered from them directly instead of through Chrysler. This is an investigation to see if we can save people money.

ok, I understand. However I spoke to a local turbo mechanic and they won't replace the REA because of the calibrating needed to get them to work properly. Apparently the REA is calibrated to the turbo at the factory and so it's easier for them to replace the whole turbo as a unit rather than spend time trying to recalibrate the REA.
At least their prices for replacing the turbo are cheaper than the dealers.

My current turbo is a Garrett 757608-0001, but to get a new one means replacing it with the newer model 765155-5007S,
does your tune work with this newer turbo too?

The new turbo part number is a drop in replacement for the original and the tune will function well with either.

They do not calibrate the REA specifically, but the control arm length from REA to vane mechanism.

Let say we bypass that REA with a resistor mod and keeping the vane always open ... Anybody have thoughts on the impact of this mod ??

Not all diesel engines have a variable geometry turbine...
