a lot of electrical components are date stamped same as some ally castings
Due to the fact that my engine is from a mid nineties car my manufacturer can't identify exactly when the engine was produced but the date range falls either side of the 31 July 1995. Thoughts before I get them to write a letter headed letter confirming...?
what engine?

Many of the castings etc are indeed stamped with differing values from 95 upwards. I'm wondering if, since it was one of the first cars in it's model, it would be possible to get them to admit it came from early 1995 which would make my life in certain areas very much easier than if it was in later 95!
cant they get an exact date from the engine number ?
No, I gave them engine number and VIN, apparently records don't date back that long (at least not production records, certainly they have records
of what engine went in what car, but it seems not when each piece was actually made).

oh thats a bit erm crap
Mmmm, it's a tough one.
Well, after a number of phone calls and emails too and fro there's no confirmation outside the possible dates given. I think I may have to
contact VOSA and ask for guidance on how to proceed. I don't want to turn up to the IVA with an engine that requires cats to pass and not have
them designed in, yet I don't want to design them in and pay for them if I don't have to have them.

For others in the same position, the folk at VOSA tell me that if the exact date is unknown the latest possible production date is taken.
Hmm after some cleaning and hunting I found a casting stamp that puts the block date outside the range given by the manufacturer and newer than the
car it was meant to have come out of.

you've got a bit of a head scratcher going on by the sounds of it
What engine / manufacturer is it ?

Audi, ABZ. Salvage place gave me a VIN from a 96 car, Audi gave me dates for the engine ranging 95-96 but couldn't be more exact but would continue to help if required, now have found an engine casting date on the block of 12/97. :S
OK. More info on this after a raft of emails to VOSAs IVA and MOT folk.
I'll try to cover it in as much detail as possible:
1) For the case of an unknown exact engine the IVA test will require you to sit the test for the newest possible engine age you know it could be (i.e.
if you have an engine that could be 95-99, it's a 99).
In the IVA you have to sit the tests specified in the IVA manual - these are fairly obviously explained and there should be no ambiguity there. The
limits for those tests are explained in the IVA and have absolutely nothing to do with the MOT tests. If you're designing for IVA it's a
totally different thing to designing for the MOT. Any new car which passes the IVA will get the limits it was tested to noted on the V5. Older cars
that didn't do the IVA obviously won't. There may be some level of confusion which means the odd newer car might not have figures.
However:
In the MOT:
A car with an age related (any non-Q) plate will get tested as per the emissions standards it sat - i.e. if it didn't do an IVA it will have very
basic testing, if it sat IVA it'll be tested to the IVA limits every MOT.
Any Q plate car currently gets visible smoke only, regardless of whether it was IVA'd yesterday, a decade ago or never.
The net result is that you design to the IVA standards to pass the IVA, regardless of future tests. If you get a non-Q plate you must stick to
those standards. If you register as a Q you get visible smoke only.
They admit there is discontinuity but this is the position they are sticking to currently.

However, before your vehicle can be registered by DVLA and put in to
service on the road it has to be approved, in the case of your vehicle
(my vehicle has a 1995-1996 engine) it
will need to undergo an IVA test in accordance with RVAR 2009. On the data
supplied for the vehicle's engine it will be tested as a 1996 engine and
required to meet advanced emission standards relaxant to that age.
quote:
Once the vehicle is registered it becomes subject to the MOT requirements
under MVTR 1981 as amended the outcome of which is determined by date of
first use.
In the case of a vehicle of indeterminate age that has been issued with a Q
plate the date of first use is considered to be the 1st January 1971 in
which case a pre 1st August 1975 emission test will apply.
Where a vehicle is given an age related plate and registered as a kit
car/amateur built vehicle then vehicles first used before 1st August 1998
(testing stations were advised of this in 2002) will be considered as a pre
1st August 1975 for emissions purposes and those first used on or after
that date will be tested to the limits recorded on the V5C.
For any other vehicle then an age related emissions test will be required.
