Hello together, the following happened to me: On October 15th, I rented a car from a car sharing company and allegedly filled up a car instead of diesel – super petrol. This is evidenced by the tank receipt. I assume that there was a confusion at the gas station. At that time there was a lot of operation and I had to go back to the car, record the mileage – and again hire me. I drove on without any problems. On November 2nd I received a call from the car sharing sub The only solution I was offered was to sign a document that would oblige me to carry all future damages in the area of the engine and the vehicle. I understand that I would have a free letter to renew the car at my expense. On 12.11 – I received a letter from the lawyer of the car sharing company. In addition to the above information, I received a letter from the lawyer of the car sharing company. I will now also be offered to turn on an expert who will examine the car and then repair any damage at my expense. Furthermore, the letter states that the car was blocked immediately after the call on November 2nd, and that there will be a significant loss of revenue due to the blocking of the car. I then asked a friendly car sharing customer to check whether the Ford Focus could still be booked on the Internet. on 12.11.2015 from 17:00-17:30 o’clock was booked by the friendly car sharing customer. I then took photos of the vehicle and started the engine. Almost a month after my alleged wrong refuelling the vehicle is still in operation – apparently without any other incidents. A refuelling from 5.11.2015 shows that it was probably also in operation in the 45th KW. Now my questions: Can one still determine after such a long time at all if the car was wrongly refuelled rde? Wouldn’t the engine or parts of the fuel system have had to be noticeable for a long time in case I really had super fuelled instead of diesel? Why did the car sharing company leave the car in operation and apparently not even get a recommendation from a workshop/manufacturer? Thank you, I’m looking forward to your answers!
