Car body work (mot’s)

Len · 04-04-2006, 17:01

I wonder if anyone knows anything about this subject. After failing the mot because of some holes in my cars sills. I decided to plash out and had two new sills fitted professionally rather than do it myself and they weren’t cheap. After the job was done I then took my car back for a retest (mot) confident that it would pass only to be told later that I had a problem.

Problem being that the sills under the car had been spot welded rather than seam welded, and apparently they should have been seam welded just like the top of the sill.

I had a quick word with the fellow that fitted the sills and he said, well.... basically rubbish. As long as the sills are fully welded along the top of the sills .i.e. to strengthen the car body then the underneath need only be spot welded just like they do when they originally assemble the cars.

Now is this true what the fitter says or is it just a case of someone trying
to create some extra work for them selves’ .i.e. mot garage.

Not 100% sure but would rather have it fully welded for my own peace of mind.

I think you are right, thats the place.
But I would be interested in knowing if it is part of the mot regulations or not.

Bur999T it’s not that simple. Have you ever tried fully welding rusty metal? Much easier to spot weld and I don’t really fancy throwing another weeks wages at a bloke for only 9 hours work. If it is true and the bottom seam has to be fully welded then I will have to do it myself but I don’t want to do it if it’s not necessary.

Just spoke to an MOT tester and he says
"If it is a cover sill it has to be fully welded both top and bottom - the only time you can weld something using spot welding is if you cut out a complete panel (anywhere on the car) and put it back as the manufacturers fitted it"

Now that’s good news because the fitter cut away my old sills and replaced them with new.
I saw them myself as he showed me them.

You will have to find out if he fit a proper manufacturers sill or if it was a cover sill, even with a cover sill they usually cut away the old one
