Story of my life....
When I bought my car back in 2011 it ticked all the boxes (low mileage, R27, colour, unmodified and still in warrany, extended warranty that is) apart from this! It just do my head in, that's the only thing I hate on my car, in fact i can't even look at it, it's that bad!
I can't believe that back in 2007 Renault would sell a car with knobs taken from the 90s lol. I also can't believe that auto lights, corner lights, auto wipers and climate was a £350 option and people would not spec it when buying new! WTF!
Anyway, I started digging into doing the conversion and as Christopher suggested it's not plug and play. Someone did it (i'll see whether I can find the link) and they literally took the whole car apart, ECU, sensors, wiring the whole lot. It's really not worth it so I ditched the idea straight away.
Good luck though!
