I have perfectly working car (well, almost perfect). Everything is working, no check-engine light, no error codes, drives, runs, acccelerates - everything is great.

And I'm on the verge of dumping my Limited 6-Speed Roadster to the junk yard because it can't be driven legally on the streets of California.

The thing is, everything is working except one little problem: EGR Data Not Ready. Because of that - I can't pass the Smog Check and therefore I can't register/renew the car.

I have spend hundreds of dollars on diagnostic. The car been through several Mercedes Specialized shops. The first thing I did I have replace the EGR Valve and the battery just for the heck of it (not me, the proffesionals at the shop replaced it, to be exact). Then I drove more than 600 miles, then I went through couple of other shops. Nobody can find what's going on with it.

One guy suggested to replace computer. Really? The whole fu---ng ECU unit that performs thousands of functions perfectly fine?

But, I said - hell with it, let's do it until I've learned to price of about $1,300.00 for the parts only. Now, I just can't believe that this is the only solution. On top of that - nobody even guarantees that this would fix the problem.

PLEASE.... Does anyone have any suggestion for me? I'm dying here...
