Obviously we all want secure networks hopefully preventing a n’ erdowell from remotely controlling certain aspects of your car. As far as I can tell, if something is wireless, it can be accessed, by someone, period. I’m sure most would pan that idea. But consider the motivation already deep within more people than you’d think. I’m not saying that this device and/or app are able to do these things. I’m commenting on the difficulty connecting, that sometimes makes me want to throw the dongle away. Just Ithe fact that the industry even allowed certain controls to be done wirelessly is beyond reckless. I don’t care how busy or active these auto repair facilities might be, this should be more of a nightmare to us than we realize. Consider that this very idea could easily be the plot of some Dystopian sci-fi movie. Take partial control of a very important car to make it appear that some world leader or whoever, swerved or did NOT avoid an obvious and serious accident to make it look like a complete accident, while it was a plot to coupe a. government. If your electric steering goes out, which has been standards on lots of cars for years now, you will not be able to steer the car. Techs say that the effort to overcome the mechanical advantage of the motor and the gearing, no person with even strong arms could move it effectively to avoid a wreck. I’m not saying that could be done now. But could it soon. These apps and hardware can control you ABS pump remotely, but the steps to use that service requires the car to be not running. Anyway, make the impossible happen, Make it more consistently easy to connect. Otherwise, it’s at the top of my list along with my Autel dongle and App. Fix it please. ### 1/5 — Won’t connect *2026-08-29* It won’t connect to any of my vehicles all it does. It is Reid my VIN and then soon as I ask it to do a health report or something like that it says don’t support any vehicle like this and I’ve used it before on this vehicle and now it doesn’t. ### 1/5 — Not good for Velar *2026-08-02, version 1.4.1* Rubbish - does scans but won’t clear any warning codes detected ### 1/5 — Latest IOS Doesn’t Work *2026-07-12, version 1.4.1* App does not work on latest IOS update. Don’t buy! ### 4/5 — Very good product *2026-07-10* It works good, but on iPad it is not fitting right, they need fix that ### 1/5 — Injector coding failure *2026-06-24, version 1.4.1* 2015 Renault megane mk3 1.5dci the system demands a 7 digi hexadecimal code. Injectors for this engine are coded with a 6 digit non hexa code. This dosent work please fix asap ### 2/5 — Ford ranger 2023 uk *2026-06-08, version 1.4.1* Like the product but this is my second one I’ve tried that doesn’t recognise my Ford ranger 2023 3lt diesel need help sorting it ### 5/5 — Capabilities FAR beyond the price *2026-05-29* This app and dongle have an absolutely amazing number of functional tests, live data, and perameter resets and even adaptation resets that would rival the very best scanners available under 1,000$USD. ### 3/5 — Reports Playback Issue *2026-05-15, version 1.4.1* After recording live data, playback of local file gets stuck on one or two parameters even when only a couple of parMeters are being played back. ### 5/5 — Me encanta *2026-04-19, version 1.4.1* Muy bueno ## Frequently asked questions about Ediag ### What does this app do?
