Well...went into the garage today with me thinking I'd be experiencing a bit of a red face in the afternoon when they told me it was just the diesel in the tank sloshing around. But no! Description of work carried out reads " Drained o/s/f sill cavity as full of water and replaced gromet " - which they told me was missing. Since this was the case since last service I think something happened then. Asked if any remedial work needed in light of road salt water filling the space they said NO. Thinking about that. They key for me was Feb 8. Drove off from office in the PM and the sloshing sounded a little more lumpy...it was ice chunks. That convinced me it might not be the fuel tank.
Still waiting for the new wipers which are on order.
Garage=Shpperds at Bishop's Stortford.
Hope edukashiunal to all.
Ali.
