Hi. I have one of these things but haven't used it in ages. What is the trick again if you have a megane with a key card? Was it press the start button or did the key card have to be in for it to work?
Some kind of tree. OT I think you just hold the start button in for 5 seconds or so, no need for key card. At least that was how it was in the Clio and they have a similar electronics to the mk2 meg.
Depends what you're doing.... Fault codes etc, just key card in, push start button. Read live data, engine on. Naith, Elm is a OBD2 device.
If it's a petrol meg, card in and hold start button without touching pedals. Release button once the steering lock disengages. If it's a dci procedure is slightly different.
