Hello, I have already read some articles about Lambda probes here, but unfortunately I could not find an answer. After my check engine lamp started to light up I had a diagnosis made in the contract workshop. The result: Lambda probe over (running capacity 165TKm). So it seems normal that it comes now. However, the friends only want for the probe 250€ + VAT. + installation, which I find plentiful expensive – I prefer to put myself under the aut 1. Which company? Bosch or NTK. The price difference is not large. 2. ox 104 or ox 104-b or 104-t – 4 lines must have them and be replaced, so much I got out. But is there anything else to consider? 3. Is it a problem to take a probe with open cable ends and continue to use the old plug? Or is there anything at the end of the original probe that drives the price up like that? would be grateful for your hints!!
