Hi, I have an 'old' 2007 (OM642) Jeep WK and the Dealership tells me that the PCM needs to be replaced. Since it's out of stock, I was wondering if I could use a 2008 PCM, the parts number are different for sure (since not the same year) but the Manufacturer's (Bosch) number are similar (starts the same). Does anyone have info or made the swap? Thanks in advance ..read more

Does anyone have any experience with the swirl valve (intake runner ) circuit on 2014+ WK2 Jeeps? I’m in New Zealand and I believe Australia/NZ versions dont have the addition position sensors on the intake manifold. Postion must be sensed inside the swirl motor assembly. I have a P201D intake Manifold Runner Control Actuator Internal Performance -Bank 1. My wiring diagram indicates there should be 5v on End Postn connector but I have 11.6v with harness connector disconnected and a square... Swirl Valve Position Circuit ..read more

My 2014 Grand Cherokee diesel has averaged 29 mpg in summer and 27 in winter under the identical local runabout trips. Six weeks ago my dealer carried out the 66A recall. The cars performance since has been negatively effected. Automatic gear change ups tend to hang onto lower ratios. Sixth and seventh most of the time, eighth gear only gets selected with light throttle on a down slope. I find myself using the paddle shifters most of the time. The fuel consumption has dropped to all time... recall 66a ..read more

I bought a Grand Cherokee new in 2014. Love the diesel, use it for towing boat/car/enclosed trailer. 146K miles. It died while towing an empty trailer on the freeway 2 months ago. 1 hour earlier in the trip I got a brief smell of rubber that lasted about 2 minutes and then went away. Stopped for fuel and checked belts and resumed driving with smell gone. One hour later experienced a sudden loss of power but continued to run smooth, all temps OK. Thought I lost the turbo.

I've had my 2014 in 4 times on check engine light. Showing exhaust system codes. They went through entire DEF system and finally found crystals in or near DEF injector. Replaced injector. Only made it 40 miles before Ck engine is back on. Headed back to dealer this week. Started all this at maybe 3000 miles. 7400 miles now. Thoughts? Others experiencing this ..read more

Thinking about a delete

I am dealing with an on and off P20EE code, and figure it is only a matter of time before it is an always on CEL. I currently have a compliant GDE tune and am thinking about a full delete. However, I have a couple of questions: 1) What is the downside to leaving the DEF and EGR in place (and just turning them off)? 2) Is there a tune that uses the same OBD flash tool as GDE (so I don't have to purchase another ..read more

I have a 2015 Jeep Ecodiesel I've had new since 10/16. Just under 25000 miles. Had my first CEL in January. It was P2BA9 (bad def detected). It was -25f that week, and I was making small trips. It cleared up on it own. Today I was about 55 miles from home and P20EE came in, then shortly after a stop at the store P1288 came in. Does anyone have any insight into these codes ..read more

Hello. I have a 2016 Jeep Grand Cherokee Ecodiesel. Have had zero issues until today. The screen says the exhaust filter is 100 % full and needs service. When I called the dealership, he said it would be a week and would cost anywhere from $3K-$5K. He said it may stop running on me. Of course my warranty expired last year but it only has 95,000 miles. What can I do that’s cheaper? Help ..read more

Strange Rattle/Clack noise when Jeep is in park

Hey guys, I have a 2015 Ecodiesel grand Cherokee, bone stock, second owner, with about 74,000 miles. I have an appointment at jeep but it’s scheduled 3 weeks out due to how busy they are. I’m not a very mechanic person, but I’m trying to troubleshoot this and get some advice. I was driving home and pulled into the gas station and left my jeep on while I ran inside. As soon as I opened the door I noticed a pretty loud rattle/clacking noise. It was almost like a soup can with a rock in it... Strange Rattle/Clack noise when Jeep is in park ..read more
