Will Restore Engine Treatment hurt a 2008 S Clubman (R55)? I added oil and the Treatment yesterday and the engine was purring afterword. This morning I get the yellow Engine Light and its running rough. Any advice on this?

thanks.

 

No rattles, smoke or weird smells from the car. Just rough running with yellow light.

 

You'll need to plug something in to the ODB-II to read what the code is, or take it to your mechanic to have them read it for you.

I had that come up on a road trip on my R55. Thankfully I have the GoPoint BT1 which allowed me to read the code. My specific one was that it was running lean and I was able to clear the code myself and it didn't come back.

Hope that helps!

 

Thanks. I'll probably take it to a mechanic tomorrow. Appreciate your post.
