smog test not completed
Hubby tried to smog his 1999 E300TD today, here in California.
The smog test was not completed because the computer is not "set" yet, according to the mechanic. It's as if the battery was recently disconnected or something, and not enough mileage has been put on the car since.
However, nothing has been disconnected for a long time, and the car has been driven quite a bit the last month.
Any ideas would be appreciated------------------thanks!

THE C350
Continuing on what Plutoe said the OBD2 smog check has a few things that it monitors so I would try to find out which one is not in the "ready" status. You can do this with many code readers as well. Also how long have you owned the car?

Guys, another stop at the smog station and hubby talking to the owner. Owner said the machine rejected the car because something in the EGR/VVT System failed.
"Reason for failure: OBD readiness not set (I/M monitor)." quote from station boss.
Will be taking the car to a MBZ mechanic tomorrow to check the EGR/VVT system to diagnose the problem.
We're the original 1999 owner. It easily passed the smog tests in the past.
If you have any suggestions as to minimizing our costs, we're listening!

The MBZ mechanic is an independent, not a MBZ employee. We've used him for years on this diesel and my 2004 C320.
This mechanic has been the only one to do any work on the car for years.
There may be an issue with what had to be added to the car in 1999 so that it could be sold in CA; we'll see.

The reason i was curious when you got the car is i was wondering if someone messed with the system to sell the car or something crazy like that.
Keep us updated. I assume you don't have a check engine light on?

No, no "check engine" light on.
The multi function indicator indicated "exterior lamp failure" a couple of months ago, and hubby re-set the bulb that has loosened in the past. Fine since then.
Not a single car problem since.

The car was taken to the mechanic this morning, and he called this afternoon to say the car was ready, but he had to leave, so the key was left in the trunk (I have another key). He quoted a modest price for the "repair", but did not identify what the problem was, nor did he leave a receipt (hubby will pay him next time he's nearby). Must have been something minor.
He told hubby that he could take the car directly to the smog station (no new mileage needed), and he did-----------smog test passed!
So now hubby suspects that this mechanic did/did not do something during the previous repair 1.5 years ago, such as not resetting what he should have.
Shall be interesting the next time the car goes to the shop. If it was the mechanic's fault (or his employee), I guess we no longer will think so highly of him!

Hubby went to the MBZ mechanic today. He "fixed" the smog RGR? reading by going to a steep hill and flooring the gas (diesel?) pedal up the hill, and revved the engine for a while while parked. His meter then showed the car was "ready" to be smogged.
It might have been due to cleaning out the injectors with that process.
Since this is our third MBZ diesel, hubby does that "flooring" occasionally, but apparently not enough. This was something taught him by other mechanics years ago.
