1996 Mercedes C230 - Dashboard gauges are not working.

My car's gauges don't work and I need to pass the CA state smog check. Will I be able to pass the test if the gauges dont work?
Answer:

The gauges are not a problem. You can pass the smog check with them not working. However if the Check Engine light is also not working, that will be a problem. When the ignition is on and the engine is not running, the Check Engine light needs to be illuminated. If it is not, your Mercedes will fail the smog check. So just make sure the Check Engine light works. posted by SmogTips Support
