I would add a recommendation to subscribe to AllData DiY for schematics, instruction for disassembly and reassembly, specifications.

I installed one on my wife's 2015 Jeep Grand Cherokee runs like new, no soot. One caveat it does not come with the motor or sensors so those must still be serviceable on your old manifold. The MAF sensor is relocated to reduce soot fouling and the electrical connector is able to reach new...

Good news/Bad news kind of answer here. This engine has an off/on switch for oil pressure, once oil pressure exceeds 12 psi the ECM/PCM says all is good. The pressure you see on your dash gauge and the Vehicle Data Center is a computer algorithm estimating what the oil pressure should be at a...

I have used my Alfa and the OBDLink MX to force regen a couple of times, my 2500 RAM and my wife's Jeep Eco. I have the PC version and on the Plotted Data selection you can select the processes that you want to view. I believe around tab 11 there is a urea level although it is MM not percent of...

I would like to correct a miss-statement, the Select Catalyst Reduction uses the DEF, the ammonia reduction and catalyst reaction reduces the NoX content in the exhaust. With a tune to eliminate the SCR or both the SCR and the Diesel Particulate Filter the tune should have removed the...

Yes a long read. I will try to provide some insight but may not be able to answer all questions. To start I own two ecodiesels, one in my 2014 RAM and one in my wife's 2015 Jeep Grand Cherokee. My RAM has 180K+ miles and my wife has 200K+ miles. First the Service Electronic Throttle System...

Manuals non-existent. Best option is the personal use ALLDATA subscription. Assembly, disassembly and specifications for re-machining. The process referred to as line boring the block is one step in what we call Blueprinting. Too complex to explain on this space but basically ensure that the...

Awesome news. I use Green Diesel Engineering tune.

Since you state that you are new to the diesel world I thought a few tips that were not mentioned until you got a resolution. Once you get the message of 100% Diesel Particulant Filter you are now in non Regen and Limp Home Mode, no top gear, down rated HP. Never shut down the engine if you have...

It depends on the code. The Service Electronic Throttle System message, which is set by some 88 conditions, will stop all Regens. Any code that sets Limp Home Mode will stop Regens. And then there are other codes that do not effect Regens. It sounds like your code, which you did not name, may be...

Am using the EPA approved Green Diesel Engineering Hot Tune. Very pleased with it, more HP, MPG and no turbo lag with lowered engine temps while towing. If you are looking for a "Name That Will Not Be Said" kit, good luck all U.S. developers and dealers have been shut down by the EPA.

Condensation?

Welcome to the Forum. The low voltage code can be diagnosed with a battery load test and charging system stress test, all performed with the dealers scanner. Replacement of the alternator, battery, voltage sensor on negative battery pole or ECM update can resolve this code. On a side note, the...

Great plan. Now the OEM HPFP is a BOSCH CP4.2 which is a twin cylinder high pressure pump. The warranty replacement will be a BOSCH CP3.0 a single cylinder slightly lower pressure pump.

Several possible issues, crank sensor, cam position sensor, HPFP failure, lift pump failure. Many times would not throw a code, you may only see an anomaly while actively scanning during start cycle. A good diesel mechanic is paramount for diagnosis. Good Luck.
