My Arosa 1.4 16v Built 2002 AUB (import from Italy according to the previous owner) is constantly causing problems and this time it is the Lambda probe again. I had only bought the car last October and had to screw it a lot already… Was not a happy purchase, because so some information was transmitted to me wrongly. Well, before I got the car, the seller had to change the Lambda probe, because it was not a happy purchase, because I had to change the Lambda probe. I had been looking for a long time and ordered a new one. Unfortunately, I had not seen that there was no plug with this one (nights over the phone ordered ^^). Now I wanted to install this one today and had to first find out that 1. the plug to which the probe is connected is 6 pole and 6 cable dr n are 2. the new probe has only 4 poles (purchased via the shop https://www.motointegrator.de/…/…onde-calorstat-by-vernet-ls040055) 3. the (old) probe was 5 pole (3 months old) Now my question is: Now that I’m an absolute beginner on the whole topic, would I like to know how to connect the whole thing properly? Can it be that the previous owner (gave several and the last one couldn’t really tell me much about the car) just plugged in a completely wrong plug and therefore there were always mistakes with the Lambda probe? Add a few pictures and maybe there is a fox here who can help me… Greetings from the Oberberg
