#10220 of 10669 EGR by 05crdjeep Oct 11, 2008 (2:43 pm)
Got EGR number two at 47000 miles (first one was at 18000).   It runs differently (better) and strangely, the shift points have migrated from 62 to 61 and from 53 to 52. When I get it into the highest lockup it now stays in that gear all the way down to 56-57 mph. The lockup at 61 used to be a little bump and now it is smoother.   Mileage is the same as before.   So the EGR situation can apparently affect the transmission shifting.

Does not seem to be much interest here anymore but I thought I would post my feelings here about my recently purchased 2006 CRD Limited. In short I love it. Just got home from a picture taking tour of the fall colors around West Virginia which included about 65% two lane roads going up and down the mountains and about 35% interstate. Close to 400 miles with an amazing 28.8 miles per gallon, I truly believe straight interstate would deliver 30+   dusty

Replying to: 05crdjeep (Oct 11, 2008 2:43 pm) This engine is fed with fuel according to a predicted acceleration under a given load. When the EGR doesn't react promptly, the acceleration isn't right and the shifting sequence is 'hesitating'. Mine has over 80,000 miles and shifts perfectly because I got rid of my EGR a long time ago. CO2 emission and fine dust particles are lower than advertised according to technical inspection every 2 years Replies to this message: winter2 (Oct 12, 2008 3:40 pm) caribou1 (Oct 13, 2008 7:35 am)

Replying to: caribou1 (Oct 12, 2008 11:42 am) Caribou,   Does the inspection include measurement of NOx (Oxides of Nitrogen)? The EGR is used to reduce that pollutant. Replies to this message: caribou1 (Oct 13, 2008 7:35 am)

Replying to: winter2 (Oct 12, 2008 3:40 pm) Winter2, Not yet, my model year 2003 is just at the limit I don't have any Lambda sensor before and/or after my catalytic element. Mine is only a diesel
#10225 of 10669 second dead battery by fust Oct 22, 2008 (2:09 pm)
need help i have a 2005 crd, at 45k my battery died and was replaced , at that time the dealer said the charging circuit was fine putting out 13.6 volts and it was likely a bad battery, well now at 90k second battery to completly fail, replaced battery myself and measured 14.5 volts on the battery when running. read the service manual and it says these spiral type batteries should not be charged at more than 14.4 volts. Can anyone with the same vehicle let me know what there battery is charching at or please provide any insight why I am losing a battery every 45k,Thanks for any help.

Replying to: fust (Oct 22, 2008 2:09 pm) My original Optima spiral AGM battery was replaced at around 20k miles on a recall of the battery with a Mopar spiral AGM battery. The Mopar spiral AGM battery lasted less than 2 years and I tried to get it replaced under the battery warranty but was told by Chrysler that it was covered under the 3 year 36k mile warranty since it was a recall replacement. (Anyone find any logic in that please let me know!) The dealer wanted $180 installed for another Mopar spiral AGM battery so I told them to piss off and went to Auto Zone and bought a $100 8 year battery that has the same specs as the $180 Mopar spiral AGM battery and the $160 OPTIMA Red Top spiral AGM battery. At the time my 2006 Jeep Liberty Diesel had 80k miles on it. It now has 91k miles on the clock.   Here are the OPTIMA specs:   Group Number: 34 (9002-002) RedTop®; Battery; Group 34; Cold Crank Amps 800; Crank Amps 1000; Reserve Capacity 110; Ampere Hour 50; Top Terminal; L-10 in.; W-6 7/8 in.; H-7 13/16 in.; BOXED;   Here are the Auto Zone Gold-Duralast for a 2006 Jeep Liberty 4WD flat plate battery specs:   O.E. group size: 34 *** 800 cold cranking Amps (1000 cranking Amps) *** -> 3 year free replacement  Duralast Gold Battery   With 3 year free replacement and 8 year warranty, I do not see the logic in spending the additional money on a AGM battery from either OPTIMA or Mopar. Do you?

Replying to: fust (Oct 22, 2008 2:09 pm) A previous blog message suggests that if you have a factory installed trailer hitch and plug that juice is contantly flowing and this may contribute to the battery failure. I had one battery replacement in my 06 with only 42K miles and I make a point of removing the key from the ignition when parked, I don't know if this makes sense but its worked for me.

Replying to: fust (Oct 22, 2008 2:09 pm) Hi fust, - 14.5 Volts is the "standard" voltage for charging a 6 element lead-acid battery. - 13.6 Volts is just not enough.   I tried charging at 13.6 Volts to maintain an unused battery over the winter season; the battery seems to build up lead oxide on both anode and cathode plates. Using fresh or sufficiently dosed electrolyte doesn't help either. The result is waisted effort and need to buy a new battery.   Older batteries were disassembled, their electrodes were cleaned (by hand) with a brush, then rebuilt, filled with new electrolyte and charged. This took half a day. I remember seeing this done here in Geneva in the late 60's. The make was OERLIKON and this is the make I use today   When you buy a new battery, check it's voltage before connecting to the vehicle. It should range between 12.7 Volts and 13.3 Volts. So if you don't put the extra energy to build a 14.5 Voltage across the battery, it will chemically balance close to nil (due to lead oxide build up on all electrodes).   My red top "Optima" didn't last long (~5 years). I chose a standard battery sized for a common diesel engine, with less cold cranking power (we use 100% synthetic oil this should not be an issue). Dims: 278x175x190 mm (OPTIMA was 254x172x200mm) Mounting type: B13 70 Amp during 10 hours 640 Amp cold cranking I prefer not to mention the cost   OERLIKON and OPTIMA both belong to "Johnson Controls Inc"

Replying to: fust (Oct 22, 2008 2:09 pm) i have sold these batteries for over twenty years average life about five to ten years caribo is right 14.4 is what it should have the battery in the crd is smaller than the standard optima it was made smaller for some reason
