I bought a second hand Ford Figo 2011. The vehicle has drove around 56k KM. Recently there was an issue with the starter motor, which I got it fixed. After that Check light is on, ford service executive suggest me to replace the ECR valve, but I think the light is on because of some lose connection (mechanic who repaired started motor did struggle while removing it) 

What should I do in this case? Should I get it replaced? I'm asking because I've not idea about this, this is my first car, if I consult any mechanic they would suggest me to replace it
