You are lucky. Getting annoyed on the SES now.. I did take out the fuses only. Gonna umplug the battery. Shoot! You might be correct! God bless you porshe rules. Let me try that.

 

I unplugged the battery already. After 30 miles light came up again...

 

It wouldnt pass inspection anyways, if the readyness tests are incomplete. I would think that the code would be for catalyst efficiency below threshold, if in fact it was because of the "CEL fix" not being effective. Maybe you really do have a faulty secondary O2. Get the P code report back

 

We need to know what the code is. It may very well be not from the exhaust.

We cannot help you on that issue without getting the code.

 

here you go... Take those 3 CEL fixes, and put them in the box.. go on ebay and order Universal O2 sensor adapter (thats how they call it now, since it eliminates CEL and passes you through the emissions)...
I had a CEL with BR exhaust for about 4 months.. code P0420 (Cat converter bellow threshold).. I bought the O2 sensor from ebay (referred by turbodan).. and i never got the CEL again.. I swear, that s**t works great, and it will only cost you about 50 bucks..
Good luck

 

It is a code P0420.... I will try the universal 02 sensor adaptor.. Thanks guys!!
