Moin to everyone It’s about a 98 V70, 144hp, gasoline. History: Sometimes it starts very badly. It doesn’t sound like a lack of fuel or too little amperes but rather like the whole engine is booming. MKL is working. After several unsuccessful selection attempts in two free workshops I drove to the Volvoglass Palace today. O-Sound:”I have to look for the old tester first”. Read out, error 3-1-4, camshaft sensor signal. The encoder sits under the top moto bearing and seems to be attached only with two cocks. Question: 1) Can you change it so easily (so unscrew it, pull it out, plug it in and screw it) or is there even more to consider? Exact position; release oil before; etc? 2) What exactly is the name of the part? camshaft signaler? camshaft sensor? camshaft sensor? I can’t find anything at Skandix. Note: The “friendly” wants to have about 150€ for changing?
