Power Steering + Speedo

[andtheace]

My wife's C3 has lost its power steering and the speedo doesn't work.

 

It happened when the fuel guage hit one bar.

 

I may be paranoid but a similar thing happened on my picasso when the fuel gauge hit one bar and resetting the ECU cured the problem. (a well known bug on the picasso forums)

 

Does anyone know what could be wrong with the C3?

 

Thanks in Advance.
