MAN B&W Equipment We Repair — By Category
MAN B&W Product Lines We Repair
Our engineers are trained on the full MAN B&W product range. Below are the major product families we service.
ME Series (ME-B, ME-C)
Medium-speed diesel engines with electronically controlled fuel injection and combustion optimization. Common repair issues include fuel injection control unit (FICU) failures, engine control module (ECM) malfunctions, and sensor signal loss that trigger shutdown alarms.
MC Series (MC-C, MC-GI)
Compact, lightweight engines for auxiliary and industrial power generation. Repair focus includes electronic governor failures, common rail fuel system faults, and turbocharger control module issues affecting load regulation.
K90 Series
Large-bore, low-speed two-stroke trunk piston engines for container ships and bulk carriers. Repair challenges include electronic fuel valve (EFV) control unit failures, cylinder pressure transducer faults, and scavenge air temperature sensor malfunctions.
Electronic Governor and Speed Control Units
Integrated engine speed regulation and load-sharing systems that communicate via CAN-bus. Common faults include sensor interface card failures, load divider board malfunctions, and unstable speed feedback loops causing hunting.
Fuel Injection Control Units (FICU)
Precision hydraulic-electronic control modules regulating fuel rail pressure and injection timing across all cylinders. Typical repair work addresses fuel solenoid valve driver failures, pressure transducer electronics degradation, and timing signal processing errors.

Common MAN B&W Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MAN B&W equipment arriving at our workshop.
- ✓Fuel Injection Control Unit (FICU) Power Stage Failure — MAN B&W fuel injection solenoid driver transistors are subjected to high-current switching cycles during each injection event. Thermal cycling, humidity ingress into the module enclosure, and solder joint fatigue on the power stage PCB commonly cause intermittent fuel delivery and engine misfire.
- ✓Engine Control Module (ECM) CAN-Bus Communication Loss — MAN B&W modern engines rely on CAN-bus networks connecting the ECM, fuel control unit, governor, and sensor interface modules. Corroded connectors, intermittent harness connections, or onboard CAN termination resistor failures cause communication timeouts and trigger safety shutdowns.
- ✓Cylinder Pressure Transducer Signal Dropout — MAN B&W K90 and ME series engines monitor cylinder pressure for combustion feedback and fault detection. Transducers fail due to thermal shock, seawater corrosion of sensor tips in marinized units, and electronics module potting compound degradation, resulting in sensor signal loss.
- ✓Electronic Governor Hunting and Unstable Speed Control — MAN B&W electronic governors (EG2000 series) regulate engine speed via feedback from alternator frequency or tachometer. Proportional-integral controller tuning drift, sensor signal noise, or load divider board component aging causes continuous oscillation in fuel rack position and speed instability.
- ✓Turbocharger Control Module Boost Pressure Regulation Failure — MAN B&W turbo boost control systems use electronic wastegate actuators and pressure transducers to maintain optimal air charge for each engine load condition. Vacuum solenoid valve stiction, pressure transducer zero-drift, and proportional control driver failures cause uncontrolled boost pressure swings.
- ✓Sensor Interface Module (SIM) Analog Input Card Malfunction — MAN B&W engines integrate dozens of analog sensors (temperature, pressure, speed) through centralized SIM modules. Input filter capacitor failures, precision resistor network drift, and analog-to-digital converter chip failures cause erroneous sensor readings and false alarm shutdown.

Frequently Asked Questions — MAN B&W Repairs
Do you repair MAN B&W equipment anywhere in India?+
Yes. Synchronics repairs the complete MAN B&W product range — engine control modules, fuel injection systems, electronic governors, sensor interfaces, and turbo control units. We offer PAN India door-to-door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are performed at our Vadodara, Gujarat facility with full documentation and warranty.
What MAN B&W engine series does Synchronics repair?+
Synchronics has expertise across MAN B&W ME series (ME-B, ME-C), MC series (MC-C, MC-GI), and K90 series large-bore engines used in container ships, bulk carriers, and industrial plants across India. We repair electronic fuel injection controls, electronic governors, fuel pressure modules, and all integrated engine management electronics. Our engineers are trained on MAN B&W diagnostic tools and have repaired engines from Indian shipyards and maritime fleets for over 25 years.
What is the typical repair turnaround time for MAN B&W fuel injection control units?+
Synchronics typically repairs MAN B&W FICU modules within 7-10 working days depending on fault severity. Critical fuel injection driver failures and solenoid transistor burnouts require PCB rework and thermal cycling validation, which may extend turnaround slightly. We offer expedited repair for vessels scheduled to depart — contact our service hotline for priority booking.
Can you repair MAN B&W engine control modules with proprietary OBD coding?+
Yes. Synchronics maintains a database of MAN B&W ECM firmware variants, operating parameters, and calibration codes. If onboard programming is corrupted or ECM configuration needs adjustment post-repair, our engineers use authorized MAN B&W service software to reprogram and commission the module to engine-specific parameters. All reprogramming is documented with pre- and post-repair configuration screenshots.
Do you provide warranty on MAN B&W repairs and spare components?+
Synchronics provides 12-month parts and labor warranty on all MAN B&W repairs performed at our facility. Replacement components (sensors, fuel injectors, solenoids) carry the manufacturer warranty period. If an engine returns to service and experiences a recurrence of the original fault within warranty, we offer free diagnosis and parts replacement. Emergency repairs can also be backed with extended warranty upon request.
How do I send my MAN B&W unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a MAN B&W drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on MAN B&W repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your MAN B&W unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
