Citroen C3 onboard computer lists of a list bogus problems:

Car: Citroen C3
Variant: 1.6 diesel
Model Year: 2004
Categories: Running Rough, Starting & Power Loss
On starting car computer display lists a number of faults, beeps etc....ABS brake fault, pollution, light sensor etc ...... the speedometer and power steering then cease to work. After driving for a few minutes the computer then resets and there is no problem. Sometimes this happens if passenger door is open when starting engine, sometimes when car has been standing in rain. Dealer says it's a tricky problem to diagnose and to try to cope to avoid a big bill.

Hard to diagnose from here but a simple test you can do is to test alternator output and also battery as a low battery / alternator can cause electrics on todays cars to act up and misbehave .Worth checking and wont cost anything to carry out .

Check the under bonnet fuse box for water ingress. Also earth strap at the gearbox.
