State car inspection organisation demands documentation on water injection kit

[tinnsoldaten]

Hi

Got my car taken to inspection and they require documentation to add it to registration as legal addition to car.

TUV or similar documentation is what they ask for.

Alternative is to remove the visible parts of waterinjection system and show to brand related shop and get document stating the engine is restored to its original form , ref water injection....

PIA....

Any one heard of anyone got this taken care of?
