Not something I have ever experienced before unfortunately, but I spent half an hour at Tesco petrol station yesterday trying to fit the diesel filler nozzle into my E Class filler "hole". Appreciate there is some kind of mechanism to stop you putting petrol in the car by mistake but I had to use three different filler pumps before I found a nozzle that would fit in the hole! Most frustrating, ended up with diesel all over my hands (and the steering wheel) and being late for work. The lady in the kiosk seemed to indicate this wasn't the first time this had happened, not surprising as MB World is 1 mile away from the garage! These nozzles weren't the "HGV type", they were standard. Anyone else had a similar experience?
