E270cdi ESP error

Question by tembamahachi posted 2 months 1 week ago in Mercedes-Benz

I have have recently bought a 2003 E270cdi, has accident history. It cuts engine while running and displays ESP error. Refuses to restart but engages cooling fan and same error message is displayed. Please assist. Engine has a slight knock sound and got two different opinions, one guy says its an injector knock and another suggested a bearing knock. I am not very knowledgeable with vehicles.
