Hello, we have the decision to take over our leased RRS. We had no problems with the car, except for two uninsolved accidents that have been repaired at LR (was good damage of a total of approx. 25K). It is the small diesel V6 Facelift from 2019 with 45000 km. Thanks to Corona we could drive it only little. After the contributions to the many engine damage I have dealt a little more with the engine. Often two things are recommended: 1. Oil change all 6 months at 2nd crankshaft (which is probably the weak point) fine balancing. I have never heard of the latter before. Now my question: Does this really bring something? We would get the vehicle with 2 years approved guarantee, after that connection guarantees from other companies are possible. Has someone just with these connection guarantees from other companies experience regarding an engine damage, because if we buy the car, we also want to drive it even more than two years.
