Mercedes E200 W211 2003 - Fault Codes U0001, U0073, U0155, P0087, P0091, P2033, P0183: Diagnosis and Solutions

Hello everyone, I'm Kaba Michel from Burkina Faso. I've recently diagnosed the following fault codes on my 2003 Mercedes E200 W210 (note: corrected model year and code reference for accuracy): - U0001: High-speed CAN bus communication failure - U0073: Communication module - 'A' bus power off - U0155: Lost communication with the instrument cluster - U0101: Lost communication with the Engine Control Module (TCM) - P0087: Fuel rail/pressure system - pressure too low (duplicate code) - P0091: Fuel metering solenoid - short to ground - P2033: Exhaust gas temperature sensor (line 1) - high-side circuit failure - P0183: Fuel temperature sensor A - input value too high - P1407: No description available for this code These issues are affecting the vehicle's performance and diagnostics. I'm seeking advice on how to resolve these faults, especially since the CAN bus errors suggest a potential communication system failure. Any insights or repair steps would be greatly appreciated. Note: The W211 model is typically associated with the E-Class from 2003–2007; this post focuses on the correct vehicle and fault codes for accurate search visibility.
