Cl600 Power issues
Hi there I'm a new member from the UK.
I love my 2004 CL600, it's the exact car I've always wanted. I'ts in great condition and I have no non standard parts fitted. Just sailed through it's last MOT with no advisories and perfect emissions.
The rub of my problem is power. Now, I'm not saying it's slow by any means but it's certainly not what I'd call a very fast car. My friends Bentley Continental GT with almost exactly the same factory horsepower rating totally leaves it in the dust. I'm showing no faults or malfunctions whatsoever. I'm loath to have it put on a rolling road because the local ones are all staffed by animals. Maybe it's a boost issue, but I would have thought that would show up on a scan. Any Ideas people?

I would start by getting the car hooked up to a STAR diagnostic computer and data log the sensors. See if anything is out of normal. When I bought my car I was in the same situation. It ran perfect, but was slower than it should be. Turned out the wrong MAP sensor had been installed in the intercooler location and I was only getting 2#'s of boost. Good luck figuring yours out.

I would also look loosely - edit - closely - at the intercooler system, which fits the symptoms.
The pump may fail without you knowing anything about it.
The common problem is air in the intercooler system, which is difficult to detect and difficult to bleed.
