Laguna transmission oil pressure fault
Summary of the thread
A 2009 Renault Laguna with 96,403 km is experiencing transmission issues, indicated by engine and transmission warning lights, and diagnosed with a transmission oil pressure sensor fault. Symptoms include emergency mode activation, gear slipping, unclean shifts, and grinding noises. The problem may be due to a faulty oil pressure sensor and low gearbox oil level. The recommended solution is to consult a workshop for proper diagnosis and repair, which was confirmed as necessary, leading to the replacement of the sensor and an oil top-up.

Thanks for the reply! The error code does specifically mention the oil pressure sensor. I haven't checked the oil level myself yet, to be honest. I wasn't sure where to start looking for the fill point and how to check the level correctly. Is it something straightforward I could do at home?

Right. If the error code is definitive about the pressure sensor, and you're experiencing shifting issues, it's wise to proceed cautiously. While checking the oil level is a good first step, given the grinding noises, it might be prudent to consult a workshop. Continuing to drive with a potential oil pressure issue could lead to further damage. They can properly diagnose the sensor itself and the overall health of your transmission. It may require specific tools and expertise. Please understand that low oil levels can cause catastrophic damage very quickly. Take it easy.

Thanks for the advice. I appreciate it! I took it to a workshop, and you were right, it was a faulty transmission oil pressure sensor and low oil. The repair, including the sensor replacement and oil top-up, came to 365€. Hopefully that's the end of it!

Hello there. I had a similar problem with my Renault Megane. The symptoms you describe sound very familiar. Before we jump to conclusions, can you confirm whether the error code specifically points to the pressure switch or sensor? Also, have you checked the transmission oil level yourself?
