Hi

he maneged to clear the air bag fault light but not the power ateering light. we tried three different machines to clear the fault light but none could comunicate to the steering ?

Please help

Did you check the fluid level anyway? Pointless going through loads of diagnostic without testing the simpler things! I mentioned in another post, by disconnecting the battery to get to the pump reservoir, you may also hopefully re-set the fault light!
