Moin together! I had already attached myself to my question in another thread, but unfortunately no answers were received there, despite 30 readers since then, that I decided to open my own thread, because the question is burning under my nails. I know you all have the topic already 1000000000…. sometimes chewed through, but it is not always about the S60, the topics partly old and/or the providers have changed. So the following: I have a 2002 S60 mi t 140hp and I’m also a bit followed by the motor light. At the moment it is the control probe, i.e. the front lambda probe, which is displayed as a fault and which was also replaced by the workshop. There was a new Bosch universal, which probably does not want to fit. If the engine is cold, it becomes a bit bumpy at the first few 100 meters. If the car is warm, however, it stops immediately and when the error has been deleted, it does not come back even with any number of rides and new stars, As long as the engine remains warm. Since this is not a permanent condition and with an original probe with almost 300€ a little bit appears, I need help with the correct probe choice. In the forum several times was called Uni-Fit, the control probe costs 95€ and, as far as I can see, has the appropriate plug. Has someone experience with the probe and can recommend it? Then we would have the Skandix house brand for 169€. Is already close twice as expensive. Can you do that? someone would say what? And last but not least the part web pages like part owners etc, which offer a lot of probes for 50-150€. Does someone have a tip at which provider, which probe can be purchased calmly? I can not necessarily see if there is the right plug on it, whether the diagnostic or control probe is and whether it fits my car. Sometimes it should be the right one for the engine, but then only Euro3, so it can not be the right one. The workshop takes back the Bosch without any problems and installs the right one. I just have to get it and I ask you for your help so that I can finally have peace of mind. PS: The probe has to fulfill Euro4. I have read that this does not necessarily have to be the case with Denso. Thank you very much.
