If you need car diagnostics or an auto electrician in Harlow, AutoNet VIP provides structured fault finding for petrol, diesel, hybrid and electric vehicles. A warning light or fault code tells you that the car has detected a problem; it does not always tell you what has caused it.
Our aim is to diagnose the cause of the fault before recommending parts or repair work, helping you avoid unnecessary component replacement and giving you a clear next step.
ECU and electronic control-unit faults
Electrical problems can cause intermittent starting issues, battery drain, warning lights, charging faults, sensor problems and unexpected behaviour. We can investigate electrical supply, wiring, control systems and related components rather than simply clearing a code and waiting for the fault to return.
A fault code is a starting point. Effective diagnostics may also involve checking live data, electrical supply, wiring, sensors, supporting components and the way multiple systems interact. This helps avoid replacing components simply because they appear in a code description.
For electric and hybrid vehicles, we can also investigate battery, charging, BMS, low-voltage and high-voltage system faults. Where appropriate, we can route the vehicle into our dedicated EV or Tesla high-voltage diagnostic service.
Alongside our diagnostic and auto electrical work, we offer ECU testing, repair, cloning and programming, plus vehicle software updates where supported. If a control-unit fault is suspected, we can investigate the cause and advise on repair or a compatible replacement.
We also offer Easy Scan and Full Scan options. Contact us to discuss which suits your vehicle and symptoms, what’s included and the current price.
Workshop only: all diagnostics, auto electrical and ECU work is carried out at our Harlow workshop. We do not offer a mobile mechanic or mobile diagnostic service.
