Default KK Diesel Turbo & EGR issue

Hey All,

I'm having some issues with my 2008 Jeep Limited KK Diesel 2.8.

Basically 20kms after filling at a different petrol station last week I noticed a loss of power, then all of a sudden I couldn't get the car above 80km on the freeway.

I had the Jeep in for a quote from Jeep Weribee and the claim it needs a turbo replacement and a new ERG Valve. They quoted $10,550 for the work.

I politely declined and collected my car. I've tried some fuel treatments and at about half empty re-filled the car at the petrol station I usually use, using Caltex Premium Diesel. Initially it seemed to be working but it's back to the loss of power. I can occasionally cut through and engage the turbo and it get's it's power back, but it intermittent at best.

I've been researching a new turbo and the EGR valve, any helps hints would be most welcome.

Thanks in advance.

new EGR is around $300

Thanks Midnight Mods, yes the Engine light is on. It went off briefly for a test drive but has been on most of the time.

I went for another drive this afternoon and on the way there, there was no power.

On the way back the power had returned but was still sluggish around 2000 rpm.

Hey Doum,

No I'm not sure, but am going to have a look at it tomorrow with my dad who's a lot more car savvy than I.

I think I'll buy a scan tool as well, seems like a useful bit of kit.

So I bought a Bosch scanner this morning and this is the result I got.

Any feedback would be appreciated.

The codes I can find online don't list a P0299 unfortunately.

Check for a blown hose from the turbo to the engine inlet, then check for a holed intercooler, then a a stuck open waste gate valve and lastly check the condition of the turbo blades both inlet and exhaust side and the turbo's free-ness.
