Hello everyone, I’m new Here and don’t know me so well yet,But I really need help! I have 2 problems at once The first one is my ABS light does not go off, and I have already developed and opened the control unit and there are also some cold soldering spots to see. If I solder the soldering points now and install the control unit again how can I get the abs light out again??? please for help, thank you already in advance. Problem 2 if I start the volvo, then he gives blue smoke from the exhaust even if he drives and even if I let him warm up comes blue mist but the temperature remains normal and in the water is also no oil, can you help me there please I am in despair Thanks in advance Greeting Andreas
