Frequently Asked Questions
What are the symptoms of a faulty engine ECU?
Typical symptoms: the car won't start despite the starter cranking, no communication with the ECU, rough running and stalling, faults from many sensors at once, check engine/EPC lights with no logical cause. Note: a damaged wiring harness produces the same symptoms - that's why we always start with diagnostics, not a death sentence for the ECU.
Repair, replacement or cloning - which should I choose?
Repair (replacing damaged electronic components, restoring PCB traces) is the cheapest option and keeps the car's original data. When repair isn't economical, we clone the ECU - transferring the entire memory contents (software, immobiliser, adaptations) to a used unit 1:1, with no dealer visit or costly online programming. A brand-new dealer ECU is the last resort.
Can you repair an ECU after water damage?
Often yes - time is critical. A flooded ECU should be disconnected from power as soon as possible and brought to us; corrosion progresses by the day. After ultrasonic cleaning and repairing the damaged circuits, most units return to full health.
The car won't start because of the immobiliser. Can you help?
Yes - we diagnose and repair immobiliser problems: lost key synchronisation, a damaged antenna, EEPROM memory errors. We also rebuild immo data when an ECU is replaced.
How much does an ECU repair cost and how long does it take?
The cost depends on the fault - typically from a few hundred to around PLN 1,500, usually a fraction of the price of a new dealer ECU (which can exceed PLN 5,000-10,000). Diagnosis and a quote always come before the repair. Standard turnaround is 1-5 working days.
Do you handle ECUs from other workshops (B2B)?
Yes - we accept ECUs by mail from workshops all over Poland: repair, cloning, data reading, file preparation. Contact us for partnership details.
