P062B code
Hello everyone. I'm new to the MB world and I am having a major issue with my 2013 Mercedes-Benz C300 4Matic Sport W204. It is throwing this code "P062B" Internal Control Module Fuel Injection Control Performance. When I am driving down the road, I lose all power, the car shows the traction control light, says "inoperable see owners manual" on the dash and eventually come to a stop. I am thinking it is either a bad fuel injector or it could be my ECM. has anyone else ran into this issue that could help point me in the right direction before I take it to a dealership? Thanks

This may be useful. In the end, the dealer performed a software update. Not sure why software would go bad.

Hey, I had looked through that thread, but the symptoms described here appear closer to what I am experiencing. It does not seem connected to how much gas is in the tank, nor do I hear any whining. Not sure if updating the software will have any effect, but it's one of the better leads so far.
