So after being told by my after market warranty company that my PAS pump hadn’t ‘failed’ because the grinding noise it was making and the burning of PAS fluid did not constitute a failure of the pump according to their engineers and as such they will not replace it... I have decided to replace it myself. From the manual I have, it seems a lot of other parts need removing Fan/shroud/drain coolant and ac anyone have any tips or experience? Got a feeling it may be a long struggle! Cheers!
