Service Bulletin/Repair Instructions
Information to owners showing the proper procedure for checking the oil level in a BITZER HVAC compressor.
Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

This Technical Service Information Bulletin (TSIB) describes an update from Meritor for the bolt torque application requirements on hub-to-rotor bolts for the front, drive and tag axles, on specific coaches equipped with Meritor EX225 disc brakes, on either Conventional, PreSet or Unitized Wheel-End hubs.
SB 3077
This Service Bulletin informs affected customers that MCI was notified by Shaw Development that the diesel exhaust fluid (DEF) tank cap requires routine cleaning to prevent the potential for crystallization build up at the vent, which may result in potential vacuum issues which could result in collapsing of the tank walls on MCI D model coaches, MCI E4500 model coaches and MCI J4500 model coaches.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
