I still need help with my problem. EGR Valve was replaced twice. First time because we thought it would help. Second time by another shop just for the heck of it, because they didn't believed me.

ECU was re-flashed to clear any possible glitches.

It's been more than 2 years ago, since my first post to this thread. I drove more than 8000 miles since then. The EGR still not ready. Do you think I need to drive just a bit more???

P.S. I know about the "driving cycle", so please don't advice that.
