Does anyone know if there is a way to check actual and expected boost levels with durametric, to see if a boost leak might be present, but not enough to throw a code


The Durametric can read boost as pressure at the throttle plate, but it has no way to detect leakage.  It will give you sensor values in milibars.  As this value can vary based upon ambient conditions, temperature, tune on the vehicle, etc., the values read can vary.


If you had an "under boost" situation, I would expect that the car should be throwing a code as well.

The reason I ask is that with the vagcom software for Audi/Vw vehicles, I can monitor the expected boost requested by the software and also see that actual boost that is being recorded by the boost pressure sensors, so it helps to determine if I am loosing boost somewhere.

mbagge01, your RS6 neighbor to the North. I have logged my CTTS on vagcom and it works just fine.  If I remember correctly I think I used the standard groups, 3, 31, 115.  The Cayenne ECU, at least my '06 CTTS uses Motronic ME 7.1.1 which is the same version as the RS6.

You can use the Vagcom on most modules. There are only very few things on the Cayenne that are not VAG modules too. PCM is one thing that will not scan but right off hand I think that is about it. I use my Durametric and Vagcom interchangeably.  If I had to do it all over I probably wouldn't have ever gotten the Durametric as Vagcom is so far ahead in capabilities but Durametric has been making great strides on each software version.
