B 200
 

Good day
I was completing some general maintenance (oil change, spark plugs etc) and replaced the battery. I replaced lights due to a low beam error and the and it still did not work. While running I was looking at the fuses and I pulled one out and heard a click . Car started but could not get it out of park and engine light on. I pushed the release button and was able to get into drive and it drove great however once in park cannot get it into gear without pushing release button. Is their a relay fuse or does this mean I must replace the ecm module...I hope not

Hello and welcome to the forum! I would suggest reading the codes before replacing any other parts. This should give you a good idea as to where the issue is coming from. Please let us know if you have any other questions.
