They are great engines and, if you email me at email@example.com
, I will send you a digital copy of the MBE900 troubleshooting and repair manual. The downside is that finding a shop that will (can) work on them is sometimes challenging, so I'd see what you can find in your area. We have a local Freightliner factory service center, but they won't work on the Mercedes engine in a Freightliner bus. Finding local service options here in Flagstaff AZ has been tough.
