I would like to check that but what it a longeron - a cross member near the bottle?Modestmillionaire said:Hi all
I had the same problem with banging underneath -front end low down.
Went into dealers about 3 times with no sucess.
I kept taking it back as I am ex Rolls Royce and Bentley engineer and dont accept anythingsuch asrattles.
Anyway the problem was the windscreen washer bottle banging on the longeron.
Same old story, great concept car, poor build and quality control.
Hope you can sort it. With mine, dropping into a pothole or very rough road did not cause it.It always happened as I said on a ridged surface where there was a frequency set up. and the wheels pattered.makem said:Thanks, I will check tomorrow. Perhaps the road where I live causes a sympathetic vibration where you say rather than the car knowing it is near home.
I did know the meaning of a monocoque body as that is one of the designs which brought about a big reduction in passenger injury. (I think, not being expert.)
You are correct, it does feel that it presses heavily and that there is no reason for it to vibrate - but believe me it will sound throughout the body.makem said:Checked today and found that the water bottle is fitted very tight to the longeron. It takes quite a bit of force (much more than the weight of water inside), to raise it maybe 2mm.
As it is in effect pressing down heavily on the longeron I doubt if there would be any vibration there. It would be quite difficult to get any sort of buffer in there due to restricted access.
Thanks for the info but I must keep looking. (Or use another way home)
How did you determine it was the washer bottle? I looked on mine and there was only a very small amount of movement.Modestmillionaire said:Hi all
