Just wondering if anyone else has experienced an EGR cooler failure. I'm at 77,000km and mine decided to throw a heap of codes which seemed to be unrelated (FCW needs service, Stability Control needs service, ABS needs service). Took it in and they had it for a couple of days diagnosing. First they thought it was a short in the wiring harness but finally came back with the cooler failing.

Nope, no EGR issues. So far in 5 years (77,000 km) I've had the following:
- Changed the alloy steering box for the upgraded cast iron one under TSB/warranty
- Oil leak from oil cooler (warrantry)
- Tiny coolant leak from water pump, replaced under warranty
- Minor coolant leak from manifold fixed (warranty)
- Coolant leak from pipes near the steering box cause by rubbing due to poor install of the steering box 2 years previously. (warranty)
- Both batteries replace under warranty

Update:

Got it back Tuesday after 7 weeks (should have been 6 weeks but the batteries died while it was at the dealership so they had to wait for replacements).

Was driving it on Saturday and had a loss of power. Could hear air escaping when on throttle. Left on a tilt tray this morning back to the dealer. My guess is that someone forgot to tighten a clamp somewhere in the intake tract resulting in a hose popping off and a massive boost leak.

I'm on my 3rd oil cooler and 3rd set of batteries. As much as I like it I think it's going to go very soon.

@AusJeepNoob
your profile says you have an EcoDiesel, but this is posted in the 2.2L 4-Cyl Turbo Diesel Engine & Exhaust forum.

it might just be me, but i've never heard of the 2.2L being referred to as an "EcoDiesel"; just in case if makes a difference, can you please clarify which powerplant we're talking about here? the 4cyl turbodiesel, or the 3.0L 6cy turbodiesel?
