I waited in que for ages yesterday at the technical section where the decisions are all made, so that i could get this straightened out.
The requirements for compliance with ADR hasent changed. You still have to comply with what was required at the time of manufacture.
The doner engine still has to retain its pollution gear where applicable.
All mods have to pass the usual tests.
The biggest change is the paperwork requirements.
1. You have to submit PRIOR to starting your project an application for modification listing every detail about your car possible, and every mod planned. This includes details like what size tyre, and how many HP it will output.
2. You still have to have engenirers approval, and certification. They must be an approved one, as listed by the licensing centre. You can use others, but if they arnt listed, then its upto the vechicle examiner at the time the car is inspected to determine is the certificate is valid.
3. Every modification now has checklists that you must fillout after the mod has been done, and these must be presented at the time of the vechicle inspection.
in the end, the actual requirements of quality of build hasnt changed. it still has to comply like before, its just that now you have to substatiate it with paperwork.
Coming from an industry that is heavily regulated by state law, and understanding the need for proceduralsation and documention, it all makes sense. They are trying to make vechicle modification accross the board the same, so that the diffeences between inspectors is minimilisied.
Despite the increaded paperwork and pain, i have to support it

. I can see why its neccessary.
Still, cant they just let us have what we want and let us be!
