Has anyone installed rock guards to protect the sides/doors?
I'm looking for side protection without loosing ground clearance, something different to the standard boiler type of tubes hanging below the chassis.

diesel consumption is way up

I have the 2005 Jeep liberty CRD, it's been to the dealers a few times with things like the turbo boost sensor, thermostat and a few software upgrades including the F-37. Not sure after which software upgrade but the car started taking a lot more diesel. From average 8L/100km it now takes 14L/100km. The main reason I bought this car was fuel economy and now I might as well drive a van. The mechanics don't know what is wrong and Chrysler said that 14L/100 is not so bad. Does anyone know what could be wrong here.

Are you running USLD? Since they changed the boost sensor it probably has soot buildup in the intake. Run some injector cleaner in your fuel. Also clean out your intake pipes from the turbo down to the egr valve. Use a mild solvent which leaves no residue. Put it back together and clean your boost sensor with brake cleaner. Last but not least, change your air filter if over 10K. If this doesn't work it's in the engine. One more thing did they check your turbo? These VNT units tend to clog the vanes from moving. If so it needs to be taken apart and cleaned.

I'm running USLD. Thanks, I will try to run the injector cleaner and maybe look at the intake pipes. I'm trying to remember when it happened and I think it was before the F-37 change. After the boost sensor replacement the car was actually better on fuel than ever before but there were still problems with the software crushing and the car stalling in which case I had to restart the car. I took it in and they said they will work on the software and transmission. I never found out what they did because they didn't put anything in the computer. All I know is that the diesel mechanic quit and went to work across the street for another dealer and they had to get him in for a few hours to work on my car. He said he changed the software but it wasn't recorded in their system. After that I think the fuel consumption went up and then I was hoping the f-37 will fix that and it never did. And yes I changed the air filter which had more than 10K and it didn't look good. Basically I was told to get rid of the car but it's not so easy because I'm leasing it. I'm just wondering how much will it cost me after the warranty runs out.

Msol... Make sure that you drain the air out of the fuel filter, that will fix your problem. Also warm it up and clean it nose, that will help; Make sure that you buy good fuel from a place that have new pumps and truckers goes a lot.

Thanks, my car is back at chrysler, they have checked everything (they say) and found nothing, they did fuel diagnostics and some other diagnostics, right now they filled up the tank and are taking it for a drive. They will record the fuel consumption and make further calls. They think there is some internal damage but that doesn't mean much to me. I've had this car for 2 years now and it wasn't like this last year, it would take more fuel in the winter but not this bad. I have a feeling nothing will be done about this but they are trying.

Nothing can be done to my car, I feel bad for the mechanics, they were trained on diesel engines by 2hour video. How would you know even what to look for with all this knowledge. They have another customer complaining about this problem after the F-37 upgrade. I found out that my car has a new processor since it was fried during one of the repairs. What else can I say but who wants to take my lease....by the way there is a site for taking over leased cars and I found two jeeps like mine with a lot less mileage, I have no chance

Msol... When you buy fuel it has to be free of water; If you bought a bad badge of fuel and the water went to the injectors, the CRD is only made to inject diesel not water. The water will damage the injectors orifes making them bigger and or destroy them. maybe the damage is not as bad as to destroy the injectors but maybe cause them to use more diesel.

I think the injectors are fine but I don't know anything anymore. My car is now working great, the dealer said nothing was done to my car but a visual inspection and when they tested the fuel consumption it was as it should be. And they were right, the fuel consumption is back to where it used to be , I can go for almost 700km on a tank. It has been 10,000 km with double the fuel consumption and now back to normal. I no longer believe the dealer that have inspected my car, this is the same dealer that did something to it last year that caused this problem. I called another dealer who tried for months to figure out why this was happening and he said that they must of done something. I guess I won't try to figure this out anymore till it starts happening again but I have a feeling it won't.
