My 2 cents on this, I bought OAM EGR valve new, nothing happened. Cleaned it out completely, nothing happened. Did the battery thing, nothing happened. Really there is prob.. nothing you can do but live with the light, and if it flashes, then you really have a problem My only suggestion is to change the solenoid, the one thing i keep forgetting to do, can't remember the name of the solenoid, but may be some 1 here can let you know, or easier, just search it, its out there, i know. But i can be wrong, and i hope you fix it, good luck Mae.
