Hello to each other, I have asked this question somewhere else, and I’d like to see it here as well. Unfortunately, the SuFu has not helped me sooo far that I don’t have to open a thread. So I want to bring clarity into my brain about the keywords crankcase and oil trap. I understand that you have to degrade the suction bridge to change the oil trap. But if I only want to clean the crankcase ventilation (according to the service plan all 90tkm chamber) If you want to remove the alternator and clean the “nipples and hoses” quickly. Can one explain to me exactly where the ventilation is located then? Is there any guidance on how to clean these nipples and how the hoses? Because there is not much to expand because of a thousand things … So concretely asked: Let’s speak of the same thing when it says: 1. Clean crankcase ventilation (according to service plan) and 2. Clean oil trap Ka I don’t really imagine, because otherwise the 90tsd customer service would cost a real fortune and would be more expensive than exchange of dental belts etc. ? Thank you all in advance for enlightening answers! Oh yes – affected car : C70 2.4 T year 2001. Thank you!
