I am having the exact same problem with my 2006 Jeep (107K miles). the problem just started back in NOV, previous to that no problems.
 
I did just have my #2 glowplug replaced (the tip was broken off). That seemed to solve the problem of the engine producing white smoke from the exhaust in the morning.
 
Also, I had the Boost Solenoid Filter (a.k.a. lawnmower filter) replaced at the same time.
 
After these two fixes, my check engine light that had been on constantly for 1 year (dealer check codes, cleared codes, codes popped up affter a few days of driving.) finally went out by itself. It came back on again a few days later ( I am guessing because of the loss of power issue: driving 73mph, then Jeep drops power and speed down to 65mph with no apparent cause). But unlike the other times the CEL would go off by itself -- the Jeep was doing great in terms of performance when the CEL went off. It seems as if I have more problems with this on cold days or when there is a strong cross wind cutting across the front of the Jeep.
 
I ma thinking it has something to do with the EGR / Mass Air Flow Control Valve / or MAF sensor. Anybody have any insight? Should I just disconnect the EGR? I tried disconnecting the MAF sensor, but it seemed as if the Jeep ran worst after I did that.

In your service manual, belts are to be inspected for cracks or signs of wear. Ours are changed by default.
Your timing belts should be changed at 100,000 miles; ours at 60,000!
The problem is: the vehicle is the same
 
When all these 'worst case conditions' are put together, the vehicle becomes excessively expensive and Jeep sales suffer from such policy.

Hi farout,
Yes, the VM 2.8 CRD is still alive
http://www.jeep.fr/cherokee/jeep-cherokee-tarifs.html
 
It's the only engine offered, and I will not change mine for this newer model.
 
I do my maintenance (engine oil + air filter) every 20,000 miles and I check the axles and transfer case oil level every 4 years. My fuel filter cartridge is good for 30,000 miles, and that's it
 
I've had this Jeep 5 1/2 years and my only regret comes from the business attitude of Chrysler who imposes to sell everything at the price level of a Mercedes. This kills the American car spirit after a while.

Hi lightnin,
A small proportion of gasoline helps diesel fuel 'filtration' at lower temperatures. It gives mobility to the paraffin (wax) contained in the fuel, in other words the paraffin does not rapidly turn into solid wax and block the flow of fuel. If you put too much gasoline the fuel will self ignite and you're in real trouble especially when you have an automatic
I used 'White Spirit', an oily paint thinner that comes out of the refining process well before diesel fuel. It's close to Kerosene that we have in our winterized fuel.
 
I have no experience with alcohol based additives.
I just read a local article saying methanol will catch water stagnating in your diesel fuel tank and make it a combustible solution. The amount of water you can mix/catch with a quart of pure methanol corresponds to 12-15 fluid oz. This suits the common rail technology assuming every filter and water separator is in good working order. We should not go beyond this volume.
If you use a quart of 'burning alcohol', you can only absorb 3-5 fluid oz of water. In this case you are putting water in the tank
