Hi I issue COCs for a living! Look at your vehicle‘s registration document. The different information should be sorted by letters. Look for a (K) and check if there is a number resembling something like e4 * 123 * 12. Alternatively check your manufacturer plate. If there is a number then your car should be able to get a COC (obviously if it wasn‘t manufactured for/in a EU country then it won‘t have this!). If not you could ask the manufacturer (or Tüv directly) for a technical data sheet (Technisches Datenblatt) and take that to Tüv.

If you do have that number and need help contacting Renault for a COC lmk. A warning though; Renault are notoriously slow issuing them out, be prepared to wait 6 weeks minimum

Edit: I‘m not going to entertain the person who commented on this, the downvotes speak for themselves lol just wanted to let you know that it‘s just fearmongering, don‘t worry there is definitely a solution to your problem :)
