MWM Equipment We Repair — By Category
MWM Product Lines We Repair
Our engineers are trained on the full MWM product range. Below are the major product families we service.
TCG 2016 Biogas Engine Series
Compact biogas-fueled engines (16 kW output) widely deployed in waste-to-energy and agro-biogas plants. Common faults include fuel injection timing drift, engine control module (ECM) communication loss, and oxygen sensor failures in harsh biogas environments.
TCG 8.5 Industrial Engine Range
Heavy-duty multi-fuel engines (275-340 kW) for prime power and cogeneration in sugar mills, textile industries, and continuous-duty applications. Susceptible to fuel system contamination, turbocharger control failures, and exhaust gas temperature sensor malfunctions.
MWM Genset Control & Synchronization Systems
Integrated electrical control systems for parallel genset operation, load sharing, and grid synchronization. Frequent issues include voltage regulator drift, frequency control instability, paralleling relay chatter, and CAN bus communication breaks under high load.
Fuel Injection & Common Rail Systems
Advanced fuel delivery systems with piezo-electric injectors and high-pressure rails. Typical failures: injector coking in biogas engines, rail pressure sensor faults, electromagnetic valve stiction, and fuel pump cavitation damage from water ingress.
Engine Exhaust Management Electronics
Emission control and temperature monitoring systems including EGR valves, catalytic converters, and SCR aftertreatment on newer MWM engines. Common problems: NOx sensor cross-sensitivity, EGR cooler fouling, and control module software calibration drift.
Startup & Auxiliary Systems
Glow plug systems, starter motor electronics, and auxiliary equipment controllers for reliable cold-start and standby power. Failures include glow plug relay timeouts, starter pinion engagement issues, and water pump controller overheating in tropical Indian climates.

Common MWM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MWM equipment arriving at our workshop.
- ✓Engine Control Module (ECM) CAN bus communication loss — MWM engines communicate via CAN protocol between fuel injectors, sensors, and main ECM. Corrosion in connector pins—exacerbated by monsoon humidity and salt spray in coastal Indian plants—breaks CAN signal integrity, causing limp-mode operation and power loss.
- ✓Fuel injection timing advance malfunction causing hard starting — MWM TCG series rely on electronically-controlled fuel injection timing for cold-start and load response. Sensor faults (crank angle, cam position) or ECM calibration corruption—common after power surges in Indian grids—cause timing to stick at base advance, making engines difficult to crank.
- ✓Genset paralleling relay chatter and load-sharing instability — MWM gensets paralleled for load-sharing depend on voltage and frequency synchronization relays. Mechanical relay wear, voltage regulator drift, or frequency droop adjustment loss—typical after 5+ years in Indian mills—causes relays to chatter and loads to oscillate between units.
- ✓Turbocharger boost pressure control fluctuation — MWM TCG 8.5 engines use electronic waste-gate actuators controlled by boost pressure feedback. Sensor drift, vacuum line cracks (common in hot industrial environments), or actuator stiction causes boost to overshoot, triggering over-boost alarms and engine de-rate.
- ✓Oxygen sensor fault codes and emission test failures — Post-combustion oxygen sensors (critical for EGR and emission control) in biogas engines foul rapidly due to siloxane deposits and moisture. Sensor circuit open-circuit or high-impedance readings disable emission feedback, triggering DTC codes and engine de-rate on newer MWM units.
- ✓Water ingress into fuel system causing cavitation pump damage — MWM fuel systems are sensitive to water contamination—particularly in Indian monsoon zones where storage tank hygiene is poor. Water causes fuel pump cavitation, injector coking, and pressure regulator valve stiction within days, leading to loss-of-fuel and engine shutdown.

Frequently Asked Questions — MWM Repairs
Do you repair MWM equipment anywhere in India?+
Yes. Synchronics repairs the full MWM product range—gas engines (TCG series), genset controllers, fuel injection systems, and auxiliary electronics. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all other major industrial cities. All repairs are completed at our flagship facility in Vadodara, Gujarat, with turnaround times of 5-7 working days for standard overhauls.
What MWM product families does Synchronics repair?+
We specialize in MWM TCG 2016 biogas engines, TCG 8.5 industrial multi-fuel engines, MWM genset synchronization and parallel control systems, Bosch common rail fuel injection modules, engine management electronics (ECM, glow plug drivers), and auxiliary pump controllers. If your MWM equipment is not listed, contact our technical team—we have access to OEM documentation for virtually all MWM industrial installations deployed in India since 1995.
My MWM genset controller shows 'CAN Bus Error' and the engine won't start. What is the problem?+
CAN bus communication failure is the most common MWM ECM fault in India, especially in coastal and monsoon-affected regions. Salt spray and humidity corrode connector pins, breaking signal lines between fuel injectors and the main control module. Synchronics uses MWM factory diagnostic software to scan all CAN nodes, measures voltage levels on twisted-pair data lines, and replaces corroded connectors with marine-grade alternatives. We then re-sync the entire engine network and perform cranking validation before returning the unit to your facility.
How often should MWM biogas engine oxygen sensors be serviced?+
MWM TCG 2016 biogas engines operating in India should have oxygen sensors inspected every 500 running hours and replaced every 1,000-1,500 hours. Biogas contains siloxanes and hydrogen sulphide that rapidly foul sensor elements, degrading emission feedback and triggering de-rate codes. Synchronics recommends upgrading to extended-life sensor harnesses with dedicated heating circuits and supplies pre-calibrated replacement sensors matched to your biogas source composition. Regular maintenance prevents costly ECM recalibration and emergency shutdown.
Can Synchronics help with MWM fuel system contamination and water ingress?+
Absolutely. Water in fuel is a leading cause of MWM engine failures in Indian monsoon zones. Synchronics performs ISO 4406 cleanliness analysis on your fuel circuit, inspects and reconditions storage tanks, upgrades fuel water-separator elements, services fuel pumps, and replaces fouled injectors. We install redundant fuel filtration and recommend quarterly maintenance intervals for high-humidity locations. After service, we validate fuel system pressure and perform load-bank testing to confirm full power restoration.
How do I send my MWM 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 MWM 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 MWM 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 MWM 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.
