Moin, I have a problem: I drive a Wagon R+, 2005 (or was 2004)… well, no matter. just under 60tkm down. now the MKL lights up and the workshop said that the Lambda probe in front of the cat is broken. they wanted about 275 euros. so suitable denso universal probe ordered (to judge the cable colors of the old one is also a universal probe and not original). now I can only get the old one absolutely not out. also with lambdasonden-nut I can put on, but by the schli tz for the cable, the nut always turns on a thing. self pressing helps nochs. the thing doesn’t move. crawl oil I sprayed on it for two days, even if you don’t want to do it on the exhaust manifold. helped 0. I don’t want to get the whole thing over too often, because otherwise the 6-angle screw connection, where you put the nut on, is still down. what is there? add new curved ones? warm up? ice spray I didn’t have there and can’t try it. n. do you have a good idea? I already know that changing the sonde is really sometimes up to the hair (I have read here already). but sometimes you are lucky and someone has the saving idea 😉 Thanks already in advance.
