NCT Woes

shakenjuggler

Hi guys, this is my first post so take it easy on me lol.

My daughters 00 Peugeot 206 failed its NCT last week due to corrosion in the passenger side sill.

Being of an engineering background and have the ability to weld, I did'nt give it a second thought. My daughter was told, when given the fail report that she just needed to "get it fixed".

Since then, I have cut out all of the corrosion to good metal, shaped a piece of steel to fit inside of the hole, seam welded, filled and shaped but stopped short of painting it and lacquering.

Took it back for a retest and lo and behold, it failed on the repair as they could not see the welds!

I am now in two minds what to do next, should I just cut it all out and weld a replacement sill in or should I finish the job and paint/lacquer and book it in for a full test?

My thinking behind the full test would be, do they still take failure results into account or is it a blank slate?

One other point is if they think the sill is a structural part of the car, what else don't they know, this particular part is made from 2mm? steel that is fixed to the longitudinal box section running the whole length passenger section of the car. The sills function is to look nice?

Any opinions/suggestions would be gratefully received.

A sill is a structural part. Having said that either take the filler out so they can see the weld or go for the plan of a full retest as they do it from scratch.

Others will answer further. There are guys here who work for Nct

Finish it off and then just take it to another test centre.

Thanks for the responses. I would prefer to go the full retest route, not just for the bodywork but for the front brakes. I have had to replace both disks and pads as two days after the first nct, the offside front caliper decided to eject one of the pads due to excessive wear.

As I mentioned, this is my daughters car so I need it to be spot on so I don't worry when she drives it.

think yourself lucky, if it was a Commercial, you'd need an Engineers report too

Wont they have the history in the NCT database showing the fault, even if does go in for a new Full Test?

Seems in the long run it would be simpler to just cut down the filler around the welds and send it back for inspection

Recently had a car fail due to rust under both sills, small hole on the left sill. A mate of mine (mechanic) got rid of the rust back to bare metal & welded a small metal plate where the hole had been. He painted on some rust preventer (forget the name). Passed the NCT re-test last Saturday. I'll do the filler & spraying myself.

As for either cutting out the filler to expose the weld joints or for cutting it all out and re-doing it again.......well...which is the easier for yourself and which will be more likely to pass? I would go with the latter. You sound fairly handy at doing this so should be no bother for you.

Good luck!
