When ECM detects a problem in the car that will cause it to run rough it can post that message in the info center.  The most often cause though is that the electronic throttle body is starting to fail. 

My recommendation would be to take it to the dealer and let them check it out.  If it is the throttle body then it will be covered under warranty as long as you have less than 200,000 miles. Although I can not tell you for sure thats what it is.


 The only way to tell for sure though is to take it to the dealer becuase only their diagnostic computer can tell you why that message is coming up, an independent shop will not be able to do that unless they are volvo only specialist.

V50 SE LUX 1.6 DIESEL ESTATE. What does Reduced Engine Performance displayed mean.


means that the ECM has put the engine in limp mode to protect it from serious damage
That means that you have to run the fault codes to determine what sensor reported a problem and to have that problem fixed asap

My Volvo c30 cuts out if I accelerate to much in gear before changing it is a diesel


there is probably an over rev stopper in the system that is intended to stop engine destruction
It is poor driving practice to put the engine in this situation as it stresses the engine unnecessarily and really achieves nothing
diesel engine have a set torque range and under or over that range produces nothing in the terms of power and gear changing should be best kept to that range
If the transmission will not change gears at around 2500 rpms then have the fault codes read as there may be a problem electronically.

What does a volvo s80 code reduced engine power mean?


The ETM (electronic throttle module) has been known to cause the "Reduced Engine Performance" code on volvos. However, there are many sensors which could have triggered this problem. If your check engine light is on, have it scanned for free at an autozone for any engine codes which may point to the culprit.

This sounds like a problem with the ETM or electronic throttle module. You need to have someone with Volvo experience scan the engine management system for fault codes. Most likely you will have codes for the throttle module. This was a very common problem with 99 and newer cars. Volvo extended the warranty on the modules to 100K on the early ones. Still have issues occasionally with the later ones-just a poor design of the sensors for throttle position in the module.
