Hi all, I am the proud new owner of a 2005 MB E320 CDI. Was my father's. He'd driven MB diesels since 1976, beginning with a '76 240D, moving through the years, a new one every 7 to 10 years, finally ending with the '05 E320 CDI.
I on...
Hi all, I am the proud new owner of a 2005 MB E320 CDI. Was my father's. He'd driven MB diesels since 1976, beginning with a '76 240D, moving through the years, a new one every 7 to 10 years, finally ending with the '05 E320 CDI.
I only mention it because having driven all of them, I find it amazing what Mercedes has done with the diesel technology over the years. That 240D was a serious turtle, just putted along no matter how far you pressed the accelerator. And his '83 300D Turbo was flat out dangerous the way it behaved just like the 240D until that turbo kicked it and off like a rocket (relatively) it went--nothing subtle about it, and talk about lag...
And now, this E320 CDI is so smooth and fast, very little lag, behaves nearly like a gasoline engine (and a very powerful one at that). My wife drives a 2005 E320 gas model and this CDI is as fast or faster and certainly feels more powerful.
At any rate, I took it in for service a few weeks ago because all of a sudden it began to feel like that old 240D--the turbo never seemed to kick in, it just putted along. I was informed that the EGR was acting up and after they tried cleaning it, it still went into what the repair man called "limp home mode" (perfect description of what it felt like).
So, long story short, he advised that we just disable it or remove it (forget which) and subsequently I've read that some are doing that as a matter or course feeling the engine runs better without it.
My question is, how can I be sure it's out of the loop in the cleanest way possible? I've read that there appear to be several ways to disable it in effect: block the vacuum tube, place a steel cap over something, etc.
Is this something I can check myself to determine exactly what the repair shop did?
Thanks in advance for any help. Best, Gary
