What kind of help are you looking for? Was the EPS warning on when it turned up to the garage do you know and did they do any checks on it? i asume it was dealer it was towed too?
Of course..Its not an uncommon fault as you've gathered..but it doesnt mean that your car would pocess the same fault..there are known issue with regards ***** ***** control unit itself which is part of the column.collapsed bearing,postion torque sensor failure..all of which require a complete column to be installed and then calibrated through the proper steps whilst on going through the steps of which with the car plugged in diagnostically..its needs to be done right! the could weell be historic fault codes they could of checked for that..aswell as full inspection of the wiring harness to the control module on the column aswell as full check on the complete charging system which the EPS relys on heavily....Because its doesnt seem to be an issue now then as you'll understand they need to see that fault and eps actually happen..
