Hello I have a polo 9n3 from 2009 (134k kilometers), which I would like to sell. Currently the ABS display lights up because a sensor is defective at the front left. However, the workshop does not advise me to repair it, since after a measurement of a cylinder head it was determined that it is no longer sealed. It was measured because the engine control light has once lit up. Otherwise the car is actually in order and in a well-kept condition. Now I wonder how and where I sell the car best and what it still has for a value. I hate to sell privately, because I have too little experience and some guidance and safety from a dealer would be important to me. I would be grateful for some advice. I live in Hamburg, if there are even concrete tips. I don’t drive the motorway anymore and can therefore only move the car in a limited way.
