spent a couple days cleaning out the dirt from under the hood of a 2010 328i
just purchased. It was full of new jersey sand and dirt. Finished now and started up car. Ran rough and died shortly thereafter. Started again...a little better. Started third time held accellerator to about 1000RPM maybe 1500RPM and it seemed smooth enough. BAck to idle and a bit rough not too bad. Stayed running. Service engine
light on...read these codes 7ec abd 7e8 just now searching for meaning. Car has only 40000 mls with no known history of issues.
JA: Is the rough idle intermittent or consistent?
Customer: truthfully only tried it three times but seemed better each time. like i said it stayed running the last. Thought I had better investigate codes before proceeding
JA: Are you fixing your 328i yourself? What have you tried so far?
Customer: yes. I'm an engineer by trade and maintain all my vehicles. I have recently bought this first BMW for the wife but this is not my first rodeo. I fully realize that the last thing done is usually the culprit. The car should be dry. It has sat for nearly 24hrs now with no apparent "puddles". I even vacuumed out the areas that seemed to hold water. I would have expectged a misfire maybe due to that but not this catalytic converter code as defined by a generic code reader.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Well you just popped up in my web search. I am good with paying a bit for some advice if skilled. My wife is not going to be all that happy. Whats the deal from hear to talk a bit more????
