B250 2013 Check Engine Light On

Dear All,

I am facing a very specific issue here. My Engine Light is on and i took it to local mechanic who deals in German cars. He checked the engine light on and diagnose as O2 sensor 1 and 2 both not working properly.we changed both of them and check engine light was reset by mechanic but after 10 day check engine light came back again.
do we have different way to reset the check engine light.

Can some one help here ? or should i go to Mercedes dealership to diagnose again ?

Really appreciate your help

Maybe it is time for you to buy an OBDII code reader.

I had one for my old BMW 325iT but sold it with the car. It was the best, could read, decode and reset without problems.

I haven't purchased on yet for my 2013 B250, but definitely will in future.

I have read good reviews on the iCarsoft model, I think there are other threads in the forum about these.

good luck!

OP, we'd love it if you filled in your profile info in user CP please. We don't know where you are in the world and the cars are all different.
