Hi, sometimes when I park up my 156, 2.4JTD  the fuel gauge drops to empty. I've checked under the car for diesel ( ) and there is none. The gauge only starts to rise VERY VERY SLOWLY after I've driven a few miles, and I know its only the gauge thats wrong but I always get an awful feeling driving when the fuel light is on. I could do with a solution to this niggle. My grandfather, who was a mechanic about 20 years ago thinks it could be a bad earth, as it does only seem to happen in damp weather - but hey, this is England - when isn't it damp? Has anyone had a similar problem? If its a DIY job I'll do it but otherwise I'll leave it to Bluebell Motor Company who are doing my MOT & 3rd Cambelt in March.
