Hi, I'm new to the forum, and new to CRD ownership (just bought an 06 Sport w/ 77k miles last weekend
). I took a risk buying it, as it already had the CEL on, but pulled the trigger anyways since I got a good deal on it. Unfortunately since i didn't have anything to compare it to, while test driving I didn't notice that the turbo a little underpowering (I can feel it now though, after knowing what the code readout is). It's not entirely gone, as I can definitely feel added power as the turbo whistles up, but if I were to describe the situation, it sounds like more whistle than power received.
Foreshadowing aside, I took it in to my local mechanic for a readout and was getting a P0299 low boost code. He did a little research and found a factory firmware update that may help (not sure which update it was). He also mentioned excess oil in or around the intercooler line that he understood to be the turbo possibly going bad. After resetting the code, he sent me on my way, recommending the factory firmware update and if the turbo was going bad, to go ahead and drive it until it dies.
After digging around these fantastic threads for the last couple days, I came up with some of my own theories and things to try. (First, a little more info, after resetting the CEL code, I drove it for 2 days highway/town driving without it coming back on - it did come back on though after romping on the throttle up to 60mph). First things first, I'm going to carve out some time soon to complete the noob guide. Second, it sounds to me like it would be a boost hose issue, and I'm going to try some things described here
http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?f=5&t=74279&p=778094&hilit=p0299#p778094. Third, I'm postulating that the oil seen may be from the CCV, and may try an EHM. Forth, I'm considering a GDE Eco Tune.
My question for you fine folk is, does it sound like I'm going down the right path, or am I chasing my tail? Is the EHM something I should try? I have nearly zero auto mechanic experience, but I've spent my whole life taking things apart and putting them back together - I'm good enough with a wrench that most of this sounds doable for me (please set me in my place if you think I may be wrong there!). And my biggest question is the GDE tune - it's a good load of money to fork out, but it seems like everyone here swears by it - is it worth it? Thanks a ton!
