Electrical issue - ABS, ESP and Power Steering light coming on (randomly)

[Paazuzu]

Late last week I pulled up at the lights and the ESP and ABS lights came on - the revs dipped a little and I think the A/C cut off for a second. The lights then stayed on for another 30 seconds and turned off again.

Today when I drove to work it did the same thing, except the power steering light came on and stayed on for the whole journey to work (about 45 mins). The steering seemed to progressively lose its power-assist.

I found a forum posting here which seems like a similar issue -> Polo Power steering problem!!!.

I'm not sure whether to start with the fuses or the battery - or it could be a grounding/earthing issue. Any tips or recommendations are welcome!
