Power Steering Ecu

[DangerMouse]

Looks like my ECU is on its way out. The light on the dash has been coming on now and again for the last couple of weeks. Had it serviced yesterday, the garage reset the ECU, but today it's come on again, this time I felt the steering go heavy. So do I get Toyota to replace the ECU costing near £400 or do I buy a second off eBay and have a go fitting it myself, looks relatively simple for a noob like me. Is it a simple swap and replace or does it need programming?? My Aygo is now 6 and half years old so I expect some things to go wrong.

It will probably need programing and the steering angle sensor alining if applicable. Also it might be a fault with the steering column motor and not the ECU.
