I understand this ps hoses is a genuine probl on the oldest models, if its the long hose in front whith the coolingloop i changed it myself last year.
real easy job, remove plasticcover under front engine, take off front left wheel, remove hose from pump under front bumper whit 17mm spanner (oil wil drain ca 0,5L) remove the end on steering sylinder from wheelvel whith 19mm spanner, the clip on the hoseturn i belive is 8mm. A little tight for spanner but no probl. I recomend you buy new hose, hope the new is better qvality than the old.
