My 2017 C63 AMG failed my inspection last week. I drove it around a few days and tried again and Failed Again, Same reason!

So that makes failing TWICE, So I have to pay again to get it inspected unless I can talk to guy into being cool.

Codes That Causes Me To Fail

-O2 Not Ready

-Heated O2 Not Ready

I got a EuroCharged Stage 2 TUNE last year and car is Stock, outside an AWE SwitchPath Exhaust.

I just emailed Sales & Jerry to ask if they turned off my O2 Sensors on My Tune? It’s stock so they shouldn’t have, BUT if they say NO they didn’t.then I’ll put back to stock tune.

If they DID Turn OFF Any of My O2 Sensors, then they can just do a Quick Modification And put them back ON and email me the update File.

I can easily put my Car’s Computer back to Stock with the MyGenius that I own and plan to do that!

Car is still under warranty so if the EuroCharge Tune wasn’t the issue, and putting back to Stock Tune doesn’t do anything, then I’ll bring to dealer and let them sort it out.

Fun Times!

Could it be that you'll just need a new O2 Sensor?

Any update on this? curious. Also was your battery disconnected for an extended period of time ?
