mb = manual boost controller.
All current generation DCX 2.4L Turbo's set this code if you run a manual boost controller due to excessively high part throttle boost. No dealer will be able to replace an entire turbo for this code as the parts are on restriction to prevent unnecessary warranty.

This is a real shame, especially since Paul's (Paw) GT is bone stock and the problem has ocurred since it was new.
Add to that - the published remedy for the problem (covered in the P0234 Overboost section) from the 2003 Powertrain Diagnostic Proceedures Manual is to
replace the turbo if the other tests do not ferret out the problem.
I do not doubt that the official decision is to overlook the procedures established for problem resolution. However that kind of precedent, if allowed to go unchallenged will go far in determining the shape of things to come.
The least they could do is to try a 3 Bar TIP. That would be the same as a cat trying to cover up limberger cheese - Not enough sand to hide the smell, but it would possibly extend the range enough that the PCM software glitch that allows this code to pop up may not surface.
I have seen 3 year olds that had more integrity in their problem resolution process than that.
