Vauxhall Astra SRi 2.0
hi i have not long bought the car it has a minor power steering fluid leak on the pipe that goes from the pump to the rack its leaking beside some sort of plug actually on the pipe is it possible it could be leaking form the switch if so is it easy & cheap enough to replace this as iv been quoted £140 plus vat for the pipe from pump to rack any ideas would be much appreciated guys
