Moin people! I would like to hear your opinion on the following issue. Maybe someone has already experienced a similar case: Just 2 months ago I sold my vehicle to private. The car was from 2004 and had 230,000KM. (Automatic gearbox) I used purchase contract from mobile. (without warranty, liability for material defects etc.) I told the buyer right at the first conversation that he did not have to expect a new car when visiting. I used the car every day for 4 years to get to work. (only 6km back and forth) I didn’t have an inspection, oil change, etc. in the 4 years. The car always ran perfectly. The buyer came, looked at the car, made a test drive and was enthusiastic. After he made a deposit, he picked up the vehicle 2 weeks later. Until then I used the vehicle daily. On the same day of the pickup he called me and told me that at full throttle (kick down) a transmission error message appears in the display. After turning off the engine everything is ok again until the next kickdown. The ”normal” driving is possible without any problems. Since I don’t have too much idea of it, I only said that such a mistake did not happen to me in 4 years and he should possibly make a transmission flush. Now I received mail from his lawyer. The buyer either calls back the full purchase price, or a compensation of 1,500€ since I received the According to his lawyer, an expert report is now being prepared which will prove exactly this. I honestly think it is difficult. The fact is that I never had such an error message because I never moved the vehicle with full throttle. How do you see it? Do I have something to worry about? According to his workshop, there is an accident in the car. Let’s go to the ”coupling” in the automatic transmission. Exchange gearbox 5,000€ !!! Do I see this wrong, or should one not expect certain wear and tear phenomena at 230,000KM ??? For your answers I am very grateful. Greetings!
