I recently purchased an Audi Q4 e-tron. When I viewed the car it was advertised with a tyre repair kit. However, when I took delivery I couldn't find the kit anywhere. I spoke with the salesman at the garage from whom I got the car and was informed by him that the tyre repair kit referred to an interior sealant coating on the 20-inch wheels that were on the vehicle when I bought it.

I thought the car would have an actual repair kit that you could re-inflate the tyre that was punctured by inserting a sealant through the valve cap. Have you heard of self-sealing tyres before?
