How to reset 1999 E 320 check engine light

Hi

My E320 keeps on showing the check engine light after every few months. Dealer resets it every time and has told me not to worry.

Does anyone know how to reset this light ? So that I dont have to go to dealer every time ?

Make sure you are using premium gasoline and have the car scanned (OBD2) most likely you will need to replace O2 sensor.

Driver side air bag light stays on. It has been reset at dealer 2 times but comes back on after a few months. How can I reset without going to dealer?


You can't. It takes a special reset tool (very expensive tool also) you don't necessarily have to go to the dealer. Many shops & body shops do it also.

Two modes will not reset


Recheck the vacuum lines that were loose--they may have been placed incorrectly (why were they loose?). Try disconnecting the battery negative connection for a few minutes, then reconnect it. That should cause the computer to reset. Make sure the check engine light is not burned out. Good luck!

Check engine light comes on after last 3 visits to the dealer.


I'm not questioning the integrity of your dealer, but why not get a second opinion? I would take the car to an autoparts store and have them read the codes stored in the computer. Most parts stores will do the scan for free and will reset the check engine light if there are no faults noted. See what fault codes their scan comes up with based on the dealer findings. There's no such thing as too much information. Hope this helped and best wishes.
