Hi

I am looking to put my car in the IVA test but the V5 document on its own is not enouth for a non cat test.
Will this fail the test? how are peaple proving original engine number.

You don't say what engine, but asuming it's a Ford, if you contact Ford with the engine number they will give you proof of age. You can also get the age from the Burton cat. but not sure that all IVA testers accept that. HTH Ray
