Have you registered the vehicle with them on the ULEZ database? .. once registered you then go the section for exemption and send them the C of C showing the vehicle details and a copy of your reg document. .
Looking at the TFL site again it states:
Required documents
Vehicle manufactured to a higher Euro standard than was mandatory (early adopters):
Copy of vehicle registration document (V5C or foreign equivalent)
Vehicle Manufacturers Conformity Certificate
Letter signed by a named individual from the vehicle manufacturer's homologation department showing the:
- Number plate (Vehicle Registration Mark)
- Vehicle Identification Number (VIN)
- Euro standard the vehicle was manufactured to - fuel type
- nitrogen oxides (NOx) value and particulate matter (PM) value (if diesel)
According to that I need the letter from the homologation department, AND the Certificate of Conformity - has anyone else managed to get this CoC out of BMW?? I just received a letter from the homologation department (copy above). This may be why my initial application failed?
I've tried the application again with what I've got, and I'll see what I get back.
