    Air suspension service light

    The Strutmaster system that I was looking at came with a "Module Fooler" to satisfy the MIL.

    Coolant leak externally from back off engine

    Not sure if that is indicative for location of leak. More than likely a function of coolant level. At idle water flow volume is at lowest but both leaks go to the valley of the block and rolling causes a slosh to the back. The only way to locate a leak on the top of the engine (EGR cooler or...

    Overheating

    Fahrenheit or Celsius? If you are reading in Celsius it would translate to F at 219 to 246deg. Water or Oil temp? If you were reading water temp the 246degF (119degC) would be at the de-rate threshold. If you were reading in F to begin with then you were not high at all. The thermostat opens at...

    Coolant leak externally from back off engine

    EGR leaks are common and there is a recall for it. The EGR leaks one of two ways, one externally which is the preferred option, two internally which causes water in the oil or un-cooled exhaust gases entering the intake sometimes causing an engine fire. My leak, same symptoms, was the banjo...

    Crank but no start

    You make my most analytical day seem simple. Keep it simple. Yep the Crank Position Sensor and Ring. One of the reflash recalls was to supplant the Crank Position Sensor as primary to the Camshaft Position Sensor, this was supposed to allow you to limp in when the Crank Tone Ring grenades (as...

    Coolant Leak in Back of engine.

    Exactly the same. About 150K miles. Coolant running off the back of the block down the transmission housing, losing a quart every 40 miles. Yep was the banjo coolant fitting to the turbo. I had the dealer replace the two return lines as well. No recall. The labor list is correct. My cost just...

    Overheating

    OK, here we go. On the ED there is a three way coolant valve which shuttles coolant between the oil heat exchanger and the transmission heat exchanger. With the factory tune the three way valve does not optimize the coolant to the radiator thus temp rises. Diesels as a family of engines run...

    What's the best ecodiesel tune today for "EGR shutoff" but keeping equipment installed?

    I used the previous GDE tune with the ECM exchange and now have the EPA Compliant GDE tune, with the hand held tuner. I noted John Jensen comment with amazement, I have changed from the GDE tune to the OEM tune multiple times with no issues. The reflash only takes a couple of minutes after you...

    Def shutdown. No warning

    I hate to pick on a dealer that I do not know, but it would appear that the tech did not clear the code so that it continued to count down, or did not do a relearn for the new DEF injector. I just recently acquired the AlfaOBD scanner and found several codes that my dealer, who I trust, should...

    Temperature sensor, low cost, located in thermostat housing. Good Luck.

    W91 Recall?

    If I remember correctly, I think this was to correct the dismal turbo lag in the original AEM (Authorized Emission Modification). It was intended to shorten the delay and return some pep to the engine. I just reinstalled my Green Diesel Engineering program, now EPA Approved, and didn't worry...

    Pedal Commander cause high pressure pump to fail?

    As several persons have stated, the Pedal Commander is not the culprit here. The cp4.2 installed on the EcoD is known to fail under a couple of situations. Presently Stellantis has issued a recall for said HPFP, solution to revert to the more dependable cp3. The HPFP will be on the path to...

    Well, the saga continues!

    Well, first things first, get that heater core replaced and the leak stopped. While it is in the shop have them check the starter relay. Good luck.

    FInally picked a truck

    Congratulations. I presently have 169K on the clock. You do not mention if it was a 4x4 or not but when you change the rear diff oil also change the front diff oil. Keep a watch on the air filter. I get an oil analysis at each oil change on all my diesels, good move. We always hand calculate the...

    Programming Accelerator Pedal

    AlfaOBDII, relearn parameters for new pedal module. The measures you have taken will be insufficient to achieve what you need to do. Since you have a deleted truck it may pay to have the AlfaOBD scanner at the ready for future use. Good Luck.

    FORD 6.7 DUALLY VERSUS STAGE 1 TUNED ECODIESEL

    My wife in her 2015 Jeep Grand Cherokee was challenged by a 2500 Ford 6.7, rolling coal and he saw nothing but her tail lights after 114 mph. Seems his delete tune may not have removed the rpm limiter. My wife's GDE tune did remove the rpm limiter.

    How many miles are you getting out of your CV Axles?

    I have all original on my 2014, 169K. Can't say the same for one lower ball joint, rear differential bearings. I have replaced single CV shafts many times on my vehicles as well as customer vehicles with no qualms. Good Luck.

    Best programmer?

    I agree with BoostN, there is much conversation on this subject, however, if you are looking to stay EPA compliant, and there is a lot of discussion there as well, then the only alternative is Green Diesel Engineering. I run their EPA approved tune on my 2014 Eco with great results. They always...

    CEL P24AE

    Well you may be able to clean the sensor, not sure how successful you may be. But clearing the code will require a scanner with DTC delete capabilities. The question regarding the count down message, this code should set a DPF full condition which will initiate a mileage count down until the...

    Cp4.2 recall letter

    I read about the upcoming recall in the trade publications while we were in Montana in June and was waiting on the recall notice. I guess, whatever the new name for FCA is, hasn't found where 100K + HPFP's are located. As a personal note I never run my fuel tank below 1/2 full just to protect...
