Check engine light on but no codes
#1
![Question](https://mbworld.org/forums/images/icons/icon5.gif)
Hi folks, A few days ago I got a error message on dashboard “Stop vehicle, shift to P leave engine running” after I saw the message, I stopped at the roadside for about 10 mins then drove back to home. The next day the message gone. However, the CEL came on. I tried two different scanners but both of them found no codes. The car runs fine, only crank a bit longer than before when cold start. I thought it could be a bad battery, so I dropped a new battery in, but the CEL still on and cold start still takes longer.
I couldn’t find any related posts or solutions, most of them are pointing to Auxiliary battery, but my start/stop works normally. What are your thoughts on this?

You could try this, hopefully it helps you discover those codes causing the CEL.https://mbworld.org/forums/w212-amg/...ml#post8904173

Remember to clip coupons before purchasing, I think you will be fine with the original version the 1.0 version but if you are planning to keep the W205 for a while, you could get the 2.0 Elite Benz version with the built-in battery and more features. I forgot what the differences are but here are some examples I found:
