I new to the forum so forgive me if it has been asked before.
I have 2008 S550 was in recent accident with Airbags deployed so I purchased from Insurance company.
I am looking for help to locate the pyrofuse to start the engine. The starter turns over.

 

Usually you need to use Xentry to re-enable start. For example, please see if this helps:

I apologize for bringing up this old post. I recently bought a 2015 Mercedes Benz C-Class, air bags were deployed and the vehicle won't start. I learned that the vehicle engine start was disabled by the ECU. This model up to newer ones, engine start is usually disabled by the ECU after a crash event. You need a professional scanner or any OBD2 scanner that had a function to re-activate the engine start. I learned this here, search for "Car Wont Start After an Accident on YOUCANIC" and you will see an article that goes over common causes and possible fixes, you can read about it yourself. I hope this information can assist someone else with a similar issue.
