We have a crd and love it . But we are experiencing one issue that I have not read on here yet . Our jeep will make a growling noise when idling and the belt vibrates. Does this in a kind of cycling pattern and is worse with the AC on . We have changed the belts as well as the alternator.
 thanks

I'm not 100% sure on this ..but have you checked bearings in the idler pulleys? I also had a "funny" sound that I had a hard time identifing and found that I had a bad bearing in one of the idler pulleys at the front of the engine. It's worth checking out.

If you are careful, you can use a piece of rubber hose, hold it to your ear and move it around with the engine running to try locating the area of loudest noise.
 
My bet is either one of the pulleys that guide the belt or the AC compressor bearings.
 
Do be careful, if the rubber hose gets caught it can pull your hand in. Use a piece long enough you can hold it to your ear with one hand and leave at least two feet between your other hand and the end of the hose you are moving around under the hood. Keep it away from the belt.

Hi
Having a problem again with the EGR valve. have a code 401 come up.is asking for a up date for the system. Phone dealer ship do not know any soft ware up dates for the EGR.
They think that it is the tubes between the EGR and engine need cleaning out.
Any ideas?

It traps all the sludge that clogs up your egr valve and is responsible for turbo failure. here it is, I bought one on EBAY and installed it myself, pretty simple; http://www.auerbach.ca/kj/provent/
The CRD is a basically a great little vehicle, however some last minute cost cutting by Jeep and meeting smog requirements, took a really super vehicle and implanted several problems. The "Lost Jeeps" forum has several articles by backyard CRD mechanics who have brought their CRD's up to their potential. Many have made their own provent like systems for penny's. And they work just about as well but with a little more maintence.
There are a few "Musts" (as I consider them) IF you want to keep your CRD running for 300k miles and increase your fuel miliage. the provent (or something like it) tops the list. second is to put in the "In Tank" fuel pump that was cut out to save manufacturing $$. A fuel pump from a 2002-2005 Dodge diesel pick up fits right in and is cheap on EBAY. The wiring is already there under the carpet behind the drivers seat. Currently your CRD pulls fuel to the engine and the cheap guitar clamps on the fuel lines are prone to leaks, which can cause stalling. with the addition of the in tank pump/sender you have a pressurized fuel system which eliminates this problem and saves wear and tear on the very expensive engine mounted pump. A high flow muffler is a worthwhile improvement. The Green Diesel ECO Tune is a bit expensive $450 but it will increase your power and give you 2 to 4 more MPG. A Transgo transmission shift kit, is a pretty simple install and costs about $35, it will make your shifting more positive.
If you intend to keep your crd for several years and do alot of towing youwill need a heavy duty torque converter, suncoast makes the best but it is $1,000 give or take a couple of hundred.
The transmission is a weak point in the CRD, although it was designed for a dodge truck, it simply cannot handle the high torque of the CRD engine.
  For those who which to remain "stock" There is a procedure referred to as "Blowing it's nose" to clean out some of the sludge (that the provent system will remove). What you do is go to a freeway onramp or an open stretch of road, stop, down shift, and then excellerate at full throttle (do not go past redline on the tach) until the black smoke that will come out of your tail pipe clears up.
Hope this helps: Bob

i had a problem with my liberty crd. the belt tensioner on the front of the motor broke. if your crd is making a ratting noise dont listen to the others and ignore it. it will break. the dealer seems to be the only place to get this part. i ordered through o'reilly's and got it for a little less than what the dealer wanted.( they ordered from the dealer and got a better price).
hope that this doesnt happen again. the price was $260.

In the USA they only made the Liberty diesel in 2005 and 2006.
They did have a grand cherokee diesel in 2010.
