The average repair takes 1–3 days. However, the timeframe can vary depending on the complexity of the issue. In some cases, repairs may take longer if we are waiting for spare parts or if the unit requires additional work.
If your situation is urgent, we may be able to supply an exchange unit to minimize downtime, or we can assist in sourcing a reliable second-hand unit. Our goal is always to get your asset back on the road as quickly and efficiently as possible.
It depends on the unit being repaired, how badly the unit is damaged, and how busy the workshop is at the time. However, at Autolectronix, we aim to provide fast and efficient service. In many cases, same-day repairs are possible if:
The repair is straightforward and doesn't require extensive diagnostics or parts replacement. The required parts are available in stock. The unit is brought in early in the day to allow enough time for the repair. To help speed up the process, the more information you can provide about the issue when bringing the unit in, the better. Details such as fault codes and wiring diagrams can be incredibly helpful, even though we already have extensive information on many of the more common units we repair.
Additionally, if a service exchange unit is available for your specific model, this can further reduce your downtime, as we can provide a replacement unit while your original is being repaired or inspected.
The repair time for ECUs depends on the complexity of the issue, availability of spare parts, and the severity of the damage. Simple repairs like replacing components are faster, while major issues like PCB burnout or water damage take longer. Advanced tools, technician expertise, and clear information from the customer can also speed up the process. Delays can occur if parts are hard to find or the workshop is busy.
Typically, we do not charge for simple testing. However, if we determine that testing fees are necessary, we will inform you once we have received the module and assessed the required testing. If fees apply, they range between R500 and R2000, depending on the extent of testing required and whether detailed test reports need to be generated.
If a testing fee is quoted and we find the module to be faulty, the testing fee will be waived, and only the repair fee will be charged.
Autolectronix provides a standard 3-month warranty on most repairs, with warranties extending up to 12 months for select items. This warranty covers defects in materials and workmanship related to the repair.
Please note, the warranty does not cover:
Further water damage. Customer abuse of the unit. Improper installation. As outlined in our terms and conditions, the module must be fitted by a qualified tradesman to maintain warranty validity.
The cost of a repair at Autolectronix depends on the specific module and the extent of the repairs required. Prices generally range from R2000 to R15,000, depending on the complexity of the work and parts required.

A computer box (ECU/ECM) is the "brain" of a vehicle, managing engine performance, fuel efficiency, emissions, and safety systems like ABS and airbags. Most modern vehicles don’t just have one computer box—there are multiple control modules managing various functions, including lights, suspension, brakes, and more. These modules work together to ensure automation, precision, and reliability. Key benefits include improved fuel economy, reduced emissions, enhanced safety, and simplified diagnostics for maintenance.
Yes, we use advanced 3D printing technology to create replacement components for structurally damaged units, ensuring precise and reliable repairs.
However, the feasibility of the repair depends on the extent of the damage and our knowledge of the PCB. We prioritize reliability and will not attempt repairs if we believe they won't meet our high standards. If there's a chance the repair might leave you stranded, we will advise you to replace the unit with a second-hand or new one instead.
Common signs of a faulty computer box (ECU) include engine misfires, poor fuel efficiency, or warning lights appearing on your dashboard. To determine if the issue lies with the ECU, the following steps should be taken:
Diagnostic Testing: Ensure the vehicle undergoes diagnostic testing to identify any fault codes indicating potential ECU issues.
Rule Out Other Issues: Before assuming the ECU is faulty, an autoelectrician should inspect the vehicle for possible causes, such as sensor malfunctions, wiring problems, or mechanical issues.
Further Evaluation: Once external issues have been ruled out, the ECU can be brought to us for advanced diagnostics and repair.

It depends. Corrosion can cause significant damage to multiple circuits on a board. In many cases, we need to repair the board first to determine if the issue has been fully resolved. Sometimes, this can be a time-consuming process, as the board may need to come back a few times to address all the damage. The repairability ultimately depends on the severity of the corrosion and where it has occurred on the board.
Corrosion repairs often involve:
Cleaning the affected areas to remove contaminants. Repairing damaged circuits, traces, or connectors. Replacing components if necessary. Testing the unit to ensure all issues are resolved.
If you believe water has entered your computer box, it’s crucial to have it inspected as soon as possible. The longer water remains inside, the more damage it will cause, potentially to the point where the unit becomes unrepairable. Acting quickly can often make the difference between saving the unit and needing a full replacement.
Autolectronix currently does not explicitly advertise emergency repair services. However, we understand that downtime for commercial trucks, heavy-duty vehicles, buses, and construction/agricultural equipment can be critical. If you have an urgent repair request, you can contact us at +27 31 700 1420 or email sales@autolectronix.co.za, and we will do our best to prioritize your repair and accommodate your needs.
In most cases, reprogramming is not necessary after a repair. Once the module is repaired, it should return to the same vehicle and function as expected without any additional programming.
However, for exchange or sale items, some form of programming may be required. At Autolectronix, we can handle most programming in-house using our specialized software before returning the unit. If in-house programming is not possible, we will recommend a trusted specialist to assist you.
If you have specific concerns about your module or repair, feel free to contact us for further assistance.
