i recently posted a thread concerning leaking diesel, after the fourth visit to my local garage, reconditioned fuel pump and new connecting pipes etc they have told me that the gear box is leaking and probably dripping onto hot pipe hence the smell in the car. they have adviced me that they are unable to precisely diagnose where the leak is and suggested i go to merc garage or auto gearbox specialist. the gearbox runs through the gears well with no clunks etc. any ideas about what the leak might be, a bit concerned that my local garage whom i have used for many years with several different cars are unable to sort this. any ideas before i spend lots more money with the merc garage
