DINEX Product Lines We Repair
Our engineers are trained on the full DINEX product range. Below are the major product families we service.
DPF Control Modules
Diesel particulate filter management systems for soot load monitoring and active/passive regeneration. Common issues: regeneration cycle failures, sensor signal errors, and clogging detection faults affecting engine derate.
SCR Catalyst Controllers
Selective catalytic reduction system electronics managing urea injection, exhaust temperature, and NOx conversion efficiency. Repair focuses on ammonia slip faults, SCR efficiency codes, and urea system malfunction diagnostics.
Engine Emissions Gateways
Multi-protocol communication modules integrating engine ECU, aftertreatment systems, and vehicle diagnostics. Failures include CAN bus errors, J1939 communication faults, and misfire/overpressure warnings.
Regeneration Monitoring Systems
Real-time soot level tracking and thermal regeneration management for DPF systems. Common problems: sensor drift in soot estimation, heater element failures, and regeneration abort codes.
NOx and Temperature Sensors
Emission gas analysis components including NOx sensors, exhaust temperature probes, and differential pressure transducers. Typical faults: sensor signal instability, zero-drift errors, and connector corrosion in high-temperature exhaust environments.

Common DINEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DINEX equipment arriving at our workshop.
- ✓DPF Regeneration Abort - SPN 5357 FMI 31 — DINEX DPF control module detects insufficient exhaust temperature or fuel injection timing mismatch during active regeneration. In Indian heavy-duty vehicles operating in dusty conditions with high soot accumulation, regeneration abort occurs when sensor readings fall below 600°C threshold due to exhaust cooler fouling or fuel quality variance.
- ✓SCR NOx Conversion Efficiency Below 90% — DINEX SCR controller detects inadequate ammonia dosing or catalyst surface degradation. Common root causes in India: low-quality urea (AdBlue) introducing contaminants, improper injection nozzle spray pattern, or thermal shock from rapid start-stop cycles in congested urban routes affecting ammonia adsorption.
- ✓Ammonia Slip Fault - Engine Derate — DINEX downstream NOx sensor signals excessive ammonia breakthrough, indicating SCR catalyst inefficiency or urea injection overdose. High ambient temperature and dusty operation typical in Indian construction sites reduces sensor responsiveness, triggering false slip warnings and engine power reduction.
- ✓DPF Pressure Sensor Drift - SPN 3251 — Differential pressure transducer in DINEX DPF monitoring system exhibits zero-drift or signal plateau, causing inaccurate soot load calculation. Extended operation in high-dust environments (quarries, cement mills, sugarcane transport) fouls sensor ports and reduces sensitivity.
- ✓J1939 Gateway Communication Loss — DINEX emissions gateway loses CAN protocol synchronization with engine ECU or vehicle body controller. Intermittent faults emerge from loose connectors, water ingress in electrical connectors typical of monsoon operation, or ECU firmware mismatch after engine maintenance.
- ✓Urea Heater Element Failure - Cold Start — DINEX SCR system cannot maintain 40°C minimum urea temperature during winter mornings or high-altitude operations. Heater cartridge burnout or PWM control failure in DINEX electronics prevents proper fluid viscosity, blocking injection nozzle.

Frequently Asked Questions — DINEX Repairs
Do you repair DINEX emission control systems across India?+
Yes. Synchronics maintains repair centers in Vadodara, Gujarat, with PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Kolkata, and 50+ industrial cities. We repair DPF controllers, SCR systems, emissions gateways, and NOx sensors for DINEX equipment used in cement, sugar, steel, mining, and commercial vehicle sectors across India. Turnaround time: 7-10 working days including diagnostics and testing.
What DINEX fault codes do you specialize in diagnosing?+
Synchronics diagnoses all DINEX emission system fault codes including SPN 5357 (DPF regeneration abort), SPN 3251 (DPF pressure sensor), SPN 1675 (SCR NOx efficiency), ammonia slip codes, J1939 gateway timeouts, and urea system faults. We access DINEX proprietary diagnostic software, read soot load histograms, regeneration cycle data, and SCR catalyst aging metrics. Our engineers cross-reference Indian vehicle operating conditions and fuel quality standards when troubleshooting code root causes.
How do you handle DINEX DPF regeneration cycle troubleshooting?+
We perform passive and active regeneration simulation tests on DINEX control modules, validate exhaust temperature sensor accuracy across 200-800°C range, measure fuel injection pulse timing, and test soot mass estimation algorithms. For Indian vehicles operating in high-dust environments, we recalibrate soot threshold parameters and regeneration frequency logic. We also inspect inlet fuel quality affecting regeneration success rates.
Can you repair DINEX equipment with water damage from monsoon or flooding?+
Yes. Synchronics offers comprehensive water-damage recovery for DINEX electronics including connector replacement, PCB ultrasonic cleaning, corrosion treatment, and capacitor replacement. We pressure-test IP67-rated housings and validate seal integrity before redeployment. For monsoon-prone regions, we recommend conformal coating and upgraded connector sealing at service time.
What is your warranty on DINEX emission system repairs?+
Synchronics provides 12-month warranty on all repaired DINEX components including DPF controllers, SCR gateways, and sensor modules. Warranty covers parts and labor for defects in workmanship. We also offer extended 24-month warranty with annual preventive maintenance package for critical industrial facilities like cement mills and sugar plants where unplanned downtime impacts production significantly.
How do I send my DINEX unit for repair?+

What is the cost of repairing a DINEX 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 DINEX 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 DINEX 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.
