Today, the 2005 Jeep Liberty is back in the shop, only this time, its for a P0299 Turbocharger Underboost code. This code could almost be considered a great plague for these Jeep CRD's because once the issue surfaces, often, it takes a whirlwind of proposed solutions before the actual issue is resolved.
Thanks for hanging out in the shop with us today. Let's get this started!
What are we doing today?
Today, we are going to identify and resolve an air/oil leak within the EGR system. Stick around for the adventure.
What are we using to complete the work?
We are using common hand tools today, a Bluetooth code reader and some elbow grease.
Do you have any concerns about today's work?
No concerns today! We simply want to get this resolved and move onto the next job.
Why did you decide to do this?
Number 1, the Jeep was in LIMP mode and #2, there was no oil on the dipstick, indicating a severe oil leak.
How are you going to fix this issue?
Inspect the vehicle's EGR, exhaust, fuel, and computer system for issues.
What's your favorite thing about working on diesel Jeeps?
We like to keep these older CRD's on the road. They run 30+ on highway MPG, have part & full time 4WD, and are modern enough to still be a daily driver.
What would you improve, if anything?
Somehow resolve all the PCM, sensor, and electrical issues these model's seem to come with.
Any additional thoughts?
We complete this work in a small 2 stall garage with limited space. You can do anything you would like to do, no matter the space you have, just plan accordingly and adjust your plans to the size of your workspace. We Believe In YOU!
What's coming to the shop in the future?
Something tells us this won't be the only time this Jeep is in the shop. We have several other projects/jobs waiting in the wings.
Are you able to do lots of work in a limited space?
Yes, without question. The biggest issues I face in our 2 stall garage is organization. Keeping the workspace organized and both stalls clear of clutter really helps with motivation, which then helps with productivity. Basically, if I see a clean workspace, I'm much more ready to dive into a project or even just scheduled maintenance like today's oil change.

We can't get enough of these Jeep Liberty diesels. Let's try to figure out why this one is throwing a P0299 Turbocharger Underboost code. Let us know what you're thinking. Thanks for hanging out! -2SG
Please I hope you see this so far you are the only man on this planet who knows about this car my jeep doesn’t like too heat up anything under 14 degrees it won’t past 95F and that’s on high way or normal driving
Could it be the thermostat? Or could it do something with the viscous heater? Cabin air doesn’t get too hot either and only throws heat when moving if left too idled it just gets cold again so far I got the heat to work a little bit better by putting some cardboard in front of the radiator but where I am sometimes weather likes to get to the -30
Ours acts the same way. We replaced the thermostat last year with no change. I’ve thought about removing the mechanical cooling fan to see how it does managing temp with the electrical fan by itself.
I get some black smoke on hard acceleration and above2500 revs. Seems to have lots of power but it’s using too much fuel and it’s Smokey. New air filter fitted.
Is the check engine light on?
@@2StallGarage no engine light. The cabin computer does say “perform service” but I don’t know how to turn this off, I just thought it might be a basic trip meter every 10k miles.
I think there is some misting of oil down under the engine (if I remember correctly) and there is a smell of diesel coming from the engine but it’s not too bad. I discovered a split two months ago in the vacuuM hose into the turbo (next to the air filter) so replaced that and was hoping that would fix the problem. Power is better but the fuel efficiency is terrible plus this smoking really ruins the driving experience
You are able to reset that perform maintenance counter by holding down reset while on the maintenance countdown screen.
Check for vacuum leaks. I had similar issues with our CRD. turned out to be the secondary runner valve. Eventually your Jeep will throw a code. 🔧
@@2StallGarage ok I don’t know if is the issue yet but…..YOU ARE AWESOME. I’ll give this all a try
Sounds good. 🔧👍
I need help. 2006 Jeep Liberty CRD Diesel: I was pulling 4k pounds for about 500 miles and the last 80 miles was a solid gradual up hill. I noticed it wasn't going into over drive about 20 miles before the big problem started. We heard a pop. Not a super loud pop but a pop any way. Noticed there was zero oil but was idling fine, just no power at all. It would move a foot and stop so I quickly shut her down. Sent a friend down 6 hours from home to pick it up. He poured a gallon of oil in it and it all ran out. He said a lot of oil was coming out of the exhaust. It doesn't overheat or smell like burnt antifreeze. Also there was no check engine light on but the oil light did come on a little and I added some oil but the oil light went off and never came back on. Did I blow my motor or am I lucky enough that this could be just the turbo or something even cheaper? I can't afford this right now. =(
Ah bummer. I would start with the turbo. I had a similar situation with a 1.9TDI in a VW. Idled fine, coolant was good, degraded power. Replaced the turbo and all was well again.
Fingers crossed it’s just the turbo. You can find them fairly cheap these days online new or reman.
Oil was pouring out the exhaust as well.
What code reader are you using I have one but for some reason it won’t sync up with the jeep ?
Bluedriver. I bought it on Amazon.
I'm having trouble with that intercooler hose on that side. Somebody had replaced mine with a generic aftermarket hose and routed it over the a/c high side line & switch, not under it, so it eventually pushed the a/c line down enough to cause it to split at the compressor fitting. Anyways, I have the new a/c line and intercooler hose, but I'm not sure how it is routed or which end is which? It looked like you might've installed it backwards from how it came out, but I couldn't really tell?
I actually think I installed it backwards at first, then realized and flipped it back the correct way. Check out this schematic which will hopefully help you get it in right. images.app.goo.gl/zx9C9BDL746P8PQi6
@@2StallGarage Awesome that's exactly what I was looking for! And yes, I believe it was backwards in the video but I really appreciate the help! Keep the CRD stuff coming! Thanks, definitely subscribing
Perfect. Keep that CRD going. 👍
@@2StallGarage Found one with under 100k miles on it and plan to get another 100 out of it.
Absolutely. 👍
Check the map sensor. I think it reads boost pressure somehow
I’ve tried with the Bluedriver but it won’t read.
