dieselheld.de experiences?

Hello, recently I had a, of course, very tempting advertisement from dieselheld.de. They probably want to sue the manufacturers for damages because of the diesel affair. So the value loss. There was the talk of cash transferred to the account only because you drive a diesel. Well, I thought, inquiry costs nothing. And in the attached letter there is now something of up to 1800 euros. However, I just don’t believe that and they just affect me very much our Besides, obviously I would have to step down all right first. Can you look at each other and write your opinion. By the way, my car is now a Kia Cerato 1.6l. Diesel of course. MfG
