Hello, I need both lambda sensors for a Megane 225. I've found various conflicting details online, especially regarding the early 225 models. Since I'm currently assembling the engine, I had the chance to read the part number directly from the sensors — both have the same marking: 8200035999. However, some sources mention different part numbers for the front and rear sensors. The 8200035999 sensor seems to be harder to find as an original part. Does anyone know more about this? magane 225 2005 APRIL
