Moinsen, I have the sitting dog on the lights. Car drives inconspicuously, no round engine run, extra consumption or anything else, the exhaust gas just doesn’t smell good 😉 That’s why a new probe is supposed to come in. Is there a manufacturer recommendation for this thing? So, for example, necessarily Bosch, NGK, Volvo or something? Because I’m just seeing it… in the spare parts search… There are probes for before and after the cat… I don’t know which one is defective with me. Dumb question alert-on…: has the old turbo-elch (auc) h already) two pieces? Greetings, Volkersson
