Firstly, I'm not a Megane specialist, but I have a lot of years tinkering with cars behind me..
If you've had two stalks in the car, and both give the error, it's probably not the stalk. (Unless there is a common fault with stalks failing..)
The car was without power for a long time - it's more likely something electronic has failed during that time. There are a lot of possible culprits on a Renault..
How to find the fault? I'd plug in my cheap code reader (one of the bluetooth ones that connects to Android devices.).
If there really are no codes, then I'd take it to a local auto-electrics place that does free diagnostics. (T.H. Flory in Middlesbrough in my case)
Renaults (and especially Megane IIs) are notorious for electrical faults. Mine currently has two, but I know if I fix one, another two will pop up..
