AGR Equipment We Repair — By Category
AGR Product Lines We Repair
Our engineers are trained on the full AGR product range. Below are the major product families we service.
AGR EGR Coolers (Plate-Fin and Brazed Aluminum)
Primary product line featuring high-efficiency exhaust gas recirculation coolers designed for stationary diesel engines, power generation sets, and marine applications. Common issues include internal fouling, coolant leakage at brazed joints, and core blockage from combustion residue accumulation in tropical Indian climates.
AGR EGR Valve Control Modules
Electronically-actuated exhaust gas recirculation valve assemblies with integral solenoid controls and position feedback sensors. These modules regulate exhaust gas flow to optimize combustion and reduce NOx emissions. Failure modes include solenoid coil burnout, stuck pintle valves, and sensor calibration drift.
AGR Thermal Integration Packages
Combined EGR cooler and valve assemblies with integrated bypass circuits for modern Euro III/IV compliant engines. These modular units face challenges with thermal cycling stress, solder joint fatigue, and corrosion in salt-laden industrial environments common across Indian coastal manufacturing zones.
AGR Sensor and Diagnostic Electronics
Temperature sensors, pressure transducers, and flow measurement devices integrated into AGR systems for real-time emission monitoring and engine management feedback. Typical faults include connector corrosion, signal noise interference, and electronic drift over extended operating hours.

Common AGR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AGR equipment arriving at our workshop.
- ✓EGR cooler internal fouling and core blockage — Combustion byproducts and soot accumulation inside the cooler core, exacerbated by poor fuel quality or extended drain intervals common in Indian industrial operations. Tropical humidity and temperature cycling accelerate deposit formation in plate-fin designs.
- ✓Solenoid coil open-circuit or shorted winding in EGR valve actuators — Thermal stress from repeated heating cycles, moisture ingress through damaged connector seals, and voltage spikes from inadequate engine harness shielding. AGR solenoid coils operating in high-temperature engine compartments are particularly vulnerable in Indian genset installations without proper EMI protection.
- ✓EGR valve pintle stiction and sluggish response — Deposits on the valve seat and pintle, combined with mechanical friction from worn guide surfaces. High-sulfur diesel fuel commonly used in Indian power plants contributes to aggressive deposit buildup within 2000-3000 operating hours.
- ✓Brazed joint cracks and coolant leakage at core seams — Thermal cycling stress from frequent start-stop duty cycles, corrosion pitting in aluminum from coolant additives, and material fatigue from pressure pulsations in heavy-duty genset duty cycles typical in Indian industrial backup power applications.
- ✓Temperature and pressure sensor signal drift or open-circuit faults — Oxidation of pin contacts in multi-pin AGR connectors exposed to engine bay humidity, loose crimped terminals, and solder joint fatigue in printed circuit boards from thermal stress. Coastal Indian facilities experience accelerated corrosion.
- ✓Bypass valve spring fatigue and loss of pressure regulation — Extended high-temperature operation, hydrogen embrittlement in high-strength spring steel, and corrosion pitting that initiates stress cracks. AGR bypass valves in Indian power plants operating continuously face cumulative stress leading to failure between 8000-15000 hours.

Frequently Asked Questions — AGR Repairs
Do you repair AGR equipment anywhere in India?+
Yes, Synchronics repairs the complete AGR product range—EGR coolers, EGR valves, thermal modules, and sensor electronics—across all regions of India. We offer PAN-India door pickup service from major metros including Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Indore, and Kolkata. All repairs are handled at our primary facility in Vadodara, Gujarat, with average turnaround of 7-10 working days for standard repairs.
What is the typical lifespan of an AGR EGR cooler, and what causes premature failure?+
AGR EGR coolers are designed for 15000-25000 operating hours in industrial duty cycles. In Indian power plants and gensets, premature failure (5000-8000 hours) is usually caused by poor fuel quality leading to excessive soot deposit buildup, inadequate coolant filtration allowing abrasive particles to erode core tubes, and thermal cycling stress from rapid on-off duty cycles. Synchronics recommends 2000-hour inspections and annual coolant analysis to prevent unexpected failures.
Can you supply genuine AGR replacement parts, or do you only offer repairs?+
Synchronics offers both repair and genuine AGR parts supply. For components beyond economical repair—such as severely corroded cooler cores, cracked valve bodies, or obsolete solenoid assemblies—we source authentic AGR replacement units directly from authorized distributors and maintain a stocking inventory for common parts. Lead times for special orders typically range from 2-4 weeks depending on part availability.
How do you ensure AGR repaired components meet OEM specifications and won't fail prematurely?+
Our repair protocol for AGR equipment includes full component testing using calibrated instruments: pressure testing for cooler integrity, solenoid coil resistance and insulation megohm testing, sensor calibration against traceable standards, and flow testing for valve response. Each repaired unit includes a test certificate documenting all parameters. We also offer a 12-month warranty on all labor and replaced internal components, backed by our ISO 9001:2015 quality management certification.
What are AGR fault codes typically seen in engine management systems, and how do you diagnose them?+
Common AGR fault codes in modern engines include P0400 (EGR flow insufficient), P0401 (EGR flow excessive), P0403 (EGR control solenoid circuit open), and P0404 (EGR position sensor out of range). Synchronics uses specialized AGR diagnostic equipment to verify valve response, perform bench testing of solenoid assemblies, and recalibrate position sensors. We provide detailed diagnostic reports explaining root causes and recommend preventive maintenance intervals specific to your genset or industrial engine duty profile.
How do I send my AGR 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 AGR 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 AGR 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 AGR 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.
