The C1 steering system is flawed and prone to either intermittent or total failure.
Common Fault Codes will be;
C1554 - power steering failure
C1552 - power supply
C1555 - motor fault
Any of these fault codes will require a replacement unit.
The item has been completely disassembled, cleaned and examined for wear and breakage. Worn out, missing or non-functioning components have been replaced with new or rebuilt components. It is the functional equivalent of a new part and is virtually indistinguishable from a new part.
No coding or programming will be required, this unit is simply plug and play.
