    Exhaust,Gas,Recirculation. As it suggests, its a method for recycling gases from the exhaust back into the intake, which if working properly will reduce emissions and increase fuel economy.

    However if EGR is on during idle, roughness, and even stalling will likely result. If EGR is on during hard acceleration, low power (from reduced air/fuel volume) is the result. At part load, lean mixtures for economy create high combustion chamber temperatures and without EGR, these conditions not only create Nox, they also foster pre-ignition and pinking, so when working 100% it does its job well, but like most things in life the more complex things become, there's more to go wrong. It would seem VX has had reliability issues with many of the EGR valves, I believe it may have been improved on new versions of the valve.

    I recently took my car in for its 30k oil/filter change (I like to change it every 10k) and asked them to check it out for possible reduced power and not running as well as it used to. Despite the fact I had not had the spanner light (limp mode) come on at all, they replaced the EGR valve under warranty so pehaps something had shown up when tech2 checks were made.
