Hello this morning it also caught me ABC lamp went on after 10 min. on red When reading out then came out hydraulic pumps defective I have a good workshop here that build me the ones out and I send the ones out for 350.- for overhaul(2 years warranty on it) now I wonder if it makes sense after the out and again installation immediately the 12L oil with the 3 filters for 350.- to buy that the system is flushed? has one thing to do with the other? I’m just afraid that when exchanging could get into the system and next the dampers would give me the spirit up if someone could tell me his opinion about it.
