EPS (electric power steering) problems - Daihatsu Sirion 1500 Sport

[Cassie8]

Intermittently my EPS (electric power steering) light comes on after Sirion is started. Leaving me without power steering.
What I gathered on the internet is:
1. that it can be a problem of too low voltage caused by either a dead battery or alternator not generating high enough voltage - I checked both and both are OK
2. checked the earth from battery to chassis and the EPS earth as well - both OK
3. then I noticed somebody wrote that he turn the steering wheel rigorously from side to side while he starts the Sirion - this action activates the "dead" power steering

I tried it and it works. My question, based on what I gathered from the internet, is this problem (intermittent EPS warning light and dead EPS) perhaps caused by a dirty EPS motor? Two Sirion owners both claimed that after a thorough clean-out of the EPS motor their systems was back to 100% functional state. It makes sense to me, I don't know if it is a DC motor with brushes. If it is, then turning the steering wheel will definitely turn the stator of the motor and enable contact with the brushes?!

I need some help please. Has anyone had a similar problem/experience with their Sirion's EPS

Thankyou Cassie8, for the advice, my power steering failed on me today, I stumbled across this forum in my search for some help, and the rigorous turning of the steering wheel helped, my power steering is activated again, Thankyou for the advice.

I have the same problem,however,although turning the steering wheel rigorously ,the problem does go away.My problem has got worse and this is now happening every day.Any guidance on a permanent cure.
