Smog Check?

[jtkkz]

Hello
Is it common problem for 1996-2000 Porsche to have to see a smog referee center after smogging the car?

I heard the OBD does not read or match up to the DMV hardware or software.

Anybody out there with late model Porsches have this same problem?

Please let me know
Thank You

This seems to be a hit and miss problem. In the last week I had three customer cars in that range.
One failed at a station, brought in the car, ran through PST diagnostics, everything fine, sent him to our regular station. Passed.
Second, sent over to our regular station, passed no problem.
Third, failed at other station, ran PST diagnostics here, everything fine, failed at our regular station.
I talked to the smog tech who told me their eqipment is supposed to automatically bypass that particlar function on these cars. All gas readings passed. They are not allowed to manually bypass that function, the referee station has that capability. It does have something to do with OBDII software, that won't show up on the CANN interface used by PST.

It is actually my friends car that I was about to purchase, but when he went to get it smogged everything passed but it did not go through due to the OBDll not allowing it to go through to the DMV. This is what was said by the smog station.

So this is a common problem on 96 993's?

Does this mean every 2 years he has to go to a referee center?

My understanding was that it is a glitch that should eventually be cleared up. The smog tech had a printout a few pages long that had various manufacturers and models that had probelms in the software. The Cayenne was also on the list.

Any idea of when this will be cleared up at the DMV?

So does this mean in 2 years form now it should be all OK?

Let me know of any more input on this subject.

Thank You for responding
