Had my 300 tdi Mot'd today, have read the various comments of rear floor panels and egr blanking etc and this is what my MOT tester stated

1) No problems with blanking EGR

2) On a 300tdi no problems removing the CAT

3) Rear floor panel must be welded not pop riveted as the seat belt fixings go through the panel and the fixing is withing 300mm of the seat belt anchor, even though the seat belt fixings are into the chasis and not the rear floor panel

4) If corrosion exists within 300mm from the seat belt fixing then it is a MOT failure, unless the rear belts and seats are removed

Have we any MOT experts on board who can comment ??, it would seem that not all MOT testers are singing from the same hymn sheet

Sounds about right.
 
Agree with all of the above...and have had many arguments on many forums bout the same thing..boot floor being the major one...just cos the tester cant see it for all the crap underneath it dont mean its a pass...that seems to be what most peeps think..lol
 
So.. if you have a rusty floor, but don't have time to repair it before the mot is due, can you take the seats off and seat belts and then it will pass?
or do you have to register the disco as a comercial vehicle?
 
So if the recieved wisdom is that the floor panel is structural because of the seat belt mountings, where did the idea that it didn't matter come from? It seems like a lot of peeps have been saying the opposite for quite a while, (not that that makes them right of course). :confused:

You don't have to take the belts out, just the seats. If the seats are removed the belts are not a testable item.
Mot Testers Manual : Section 5.1 Seat Belts
"If a belt is fitted, but there is no corresponding seat it is NOT considered to be a seat belt, for the purpose of this inspection"
 
Wheather you remove egr or not or remove cat or not as long as emissions are below required level ( 2.50 non turbo 3.00 turbo) then it will pass test. Cat only essential on post 1993 petrol engines. Yes seat belt mountings are through the floor and onto chassis however ANY corrosion in and around seat belt mounts are MOT fail and inside the vehicle they are bolted through the boot floor which has probably rotted away.
 
Mine went through last year with the seats and belts taken out of my 300tdi. MoT tester thought it was damn cheeky but it passed with about four pages of yellow warnings :O

Still working my way through the rust, but should be back to 7 seats shortly :blabla:
 
MOT testers have a tough job but they've got the boot floor of a Disco right up their arse. The rear seat belts do not bolt to the floor, they go through the floor to the chassi. The rear seat do not bolt to the floor, they bolt to the surrounding metal work. The rear most body mounts do not rely on the boot floor for strength.
The 'Testers Manual' needs to be re-written by someone with mechanical experience and not by just someone with a pen in hand.

If you cut the boot floor out, would it pass? Presumably the "rust within a certain distance" rule wouldn't apply if the rust wasn't there? You could bolt a new floor in afterwards, and remove it annually for the test?:confused:
 
where i take my 300tdi disco for mot the guy is a landy nut so when i asked him about decatting he said it is mot fail as any car that leaves the factory with a cat has to have a cat on for the mot :doh:

well he's a numpty.
first off there's no such thing as a cat on a diesel - it's a particulate filter.
secondly, there's nothing in the MOT tester's manual that says that and how would the tester know anyway? the only thing that's tested is the emissions, with different limits for turbo and non-turbo engines and just a smoke test for pre 1973 vehicles.
TDis ans TD5s will pass easily without their "cat", unless there's another fault.
 
My MOT tester stated the same not interested in a cat on a diesel. this year I had blanked the EGR my reading on exhaust emissions were as follows

Both years test limit applied 1.5 l/m

Absorption coefficient 2008 0.70 Zero drift 0.01 Absorption coefficient 2009 0.31 Zero drift 0.00

50% less this year, Is this due to the EGR removal ??

As I understand it, not all diesel LRs have a "cat", and the replacement pipe is a standard part. So the tester would have no way of knowing if one had been fitted before, so long as you use the right pipe and do a professional job.
 
All of this tallies with my experience...which is why I have a 2 seater Disco at the moment. It is going back for a re-test in this state this afternoon. At the time it failed I talked it through with the tester and he said he will pass it with the seats removed but the records will show it was a two seater when it passed the test. He was not certain but didn't think it will need a re-test when I have finished the welding and put the seats back.

Could (or does) the tester put the VIN number in to his computer before he does the test and be told that it was fitted with a CAT when it was built?
