AVL Equipment We Repair — By Category
AVL Product Lines We Repair
Our engineers are trained on the full AVL product range. Below are the major product families we service.
PUMA Open ECU
Flexible engine control unit platform for powertrain development and real-time hardware-in-the-loop testing. Common faults include CAN communication timeouts, DAC/ADC conversion errors, and firmware corruption affecting calibration data integrity.
IndiCom Data Acquisition System
Multi-channel analog and digital data acquisition for combustion, pressure, and temperature monitoring in engine test cells. Repair issues involve sensor input conditioning failures, USB interface instability, and signal noise in high-temperature measurement applications.
FTIR Emissions Analyzer
Fourier-transform infrared spectroscopy system for real-time NOx, CO, CO2, and hydrocarbon measurement during engine durability and emissions certification testing. Typical failures include optical path degradation, laser alignment loss, and detector cooling circuit faults.
Indicom Combustion Analysis
High-speed pressure measurement and heat release calculation for in-cylinder combustion diagnostics. Common problems are charge-coupled device (CCD) sensor saturation, trigger signal misalignment, and data synchronization loss across multi-cylinder engines.
AVL Test Cell Control Software
Real-time Windows kernel and embedded logic controllers managing dynamometer, fuel system, and emissions sampling during standardized test cycles (NEDC, WLTP, BS-IV, BS-VI). Faults include soft real-time scheduling failures, network adapter driver conflicts, and data logging corruption.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AVL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AVL equipment arriving at our workshop.
- ✓CAN Bus Communication Loss in PUMA2 ECU — AVL PUMA2 modules experience intermittent CAN transceiver failures due to high electromagnetic interference in dynamometer bays. Degraded isolation coupling or failed TJA1050 CAN physical layer chips prevent proper message handshaking between the ECU and test cell controller nodes.
- ✓IndiCom Sensor Input Saturation and Clipping — AVL IndiCom data acquisition channels saturate when high-pressure piezoelectric sensors exceed input scaling limits, causing peak signal loss during peak cylinder pressure measurement. Inadequate anti-aliasing filter configuration or sensor amplifier gain miscalibration produces distorted waveforms unusable for combustion analysis.
- ✓FTIR Optical Path Misalignment and Signal Dropout — AVL FTIR-4100 systems experience optical mirror drift and laser beam steering loss when vibration isolation mounts degrade or thermal expansion causes mechanical expansion misalignment. Detector responsivity also degrades from carbon dioxide condensation on optical surfaces in humid Indian climate test facilities.
- ✓Test Cell Controller Real-Time Loop Dropout — AVL test automation systems running PUMA control firmware experience soft real-time scheduling failures when Windows background processes or USB driver updates trigger kernel preemption delays exceeding 100 microsecond cycle time. This causes loss of dynamometer load synchronization during transient acceleration ramps in WLTP cycle execution.
- ✓Indicom Combustion Trigger Signal Jitter — AVL Indicom pressure measurement systems lose cylinder timing synchronization when crankshaft encoder signals degrade due to worn ferrous-ring reluctor sensors or damaged optical encoder discs. Trigger signal jitter exceeding 0.2 degrees crank angle prevents accurate heat release calculation for multi-cylinder engine mapping.
- ✓Emissions Data Logging File Corruption and Incomplete Test Records — AVL test cell control software experiences data file corruption when USB storage connections intermittently disconnect during long-duration durability cycles, leaving incomplete test records that fail regulatory certification audits. Hard drive controller firmware bugs in older PUMA systems also cause sector allocation errors.

Frequently Asked Questions — AVL Repairs
Do you repair AVL equipment anywhere in India?+
Yes. Synchronics repairs the complete AVL product portfolio including PUMA Open ECU controllers, IndiCom data acquisition systems, FTIR emissions analyzers, and Indicom combustion analysis modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Equipment is transported to our certified repair facility in Vadodara, Gujarat, where our specialists perform complete diagnostics, component-level repair, and full functional validation before return.
What is the typical turnaround time for AVL PUMA2 ECU repair?+
Standard AVL PUMA2 ECU diagnostics and repair takes 5-7 working days from facility receipt. This includes full embedded firmware verification, CAN transceiver module testing, calibration data backup/restore, and NEDC cycle validation. We offer expedited 24-48 hour turnaround for critical path items affecting active OEM development schedules. During monsoon season or peak emissions testing windows, advance booking is recommended to ensure availability.
Can Synchronics repair AVL FTIR analyzers used for BS-VI emissions compliance testing?+
Yes. We specialize in AVL FTIR-4100 and FTIR-i60 optical system repair for BS-VI NOx, PM, and hydrocarbon measurement compliance. Our engineers perform optical alignment, detector responsivity calibration using certified reference gas bottles, and linearity verification across 0-2500 ppm measurement ranges. All repairs comply with ARAI/SIAM emissions certification standards and deliver complete calibration certificates required for regulatory submission.
What happens if AVL equipment cannot be repaired economically?+
Synchronics provides transparent repair feasibility assessments within 48 hours of diagnostics. If component replacement cost exceeds 60-70% of replacement equipment value, we recommend refurbished market alternatives or sourcing used modules from our network of European surplus suppliers. We never perform unnecessary repairs — our goal is maximum uptime at lowest total cost of ownership for Indian automotive manufacturers.
Do you provide on-site AVL equipment support at test facilities?+
Yes. For Tier-1 suppliers and OEMs running continuous WLTP/BS-VI testing schedules, Synchronics offers on-site preventive maintenance contracts and emergency repair support at customer facilities in Mumbai, Pune, Delhi, and Bangalore. Our mobile technicians carry common AVL replacement modules (CAN transceivers, sensor amplifier boards, USB interface cards) to minimize test cell downtime during critical certification phases.
How do I send my AVL 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 AVL 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 AVL 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 AVL 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.
