I've been asked to look at a 2011 Peugeot 207 with dead power steering. There were a couple of CAN-BUS errors on the engine ECU but they cleared OK and haven't come back. Internal module error on the BSI that also cleared and hasn't come back. The EPS is not working at all. The only fault code on the EPS is P0606 - which is described as internal ECU error.
Now I know what a quality motor these things are and how bad the steering racks are for failing electronically. I have been reading forum posts (as you do) and a couple seem to insist that it is the main engine ECU that causes the EPS module to throw this P0606 fault code. Has anyone had this and did it actually turn out to be the engine ECU and not the EPS rack/module?
Obviously I don't want to dive in and change the rack i its not that - even though thats what it looks like to me. Any help appreciated.
