Problem with engine power and ABS system in Renault Scenic 2006 - looking for solutions

Hi guys, I have a strange problem with my Renault Scenic, year 2006, diesel. I notice a loss of engine power, the ABS warning light is on, I'm losing traction and the ABS system doesn't seem to be working. I suspect it has something to do with the supply voltage to the speed sensor (ABS), but I'm not sure. Have any of you had similar experiences or any tips on how to solve the problem? How did your garage solve the problem? I look forward to hearing your experiences and advice.

Summary of the thread

A Renault Scenic 2006 owner is experiencing a loss of engine power, an active ABS warning light, and traction issues, suspecting a problem with the supply voltage to the ABS speed sensor. A suggestion was made to consider a faulty ABS control unit as a potential cause, based on a similar issue with a Renault Megane. Additional advice includes checking for corrosion around the wheel sensors and ABS control unit, as salt and moisture could lead to contact corrosion affecting the speed sensor's function. The owner plans to have the vehicle inspected by a specialist.

Hi buddy, I had a similar problem with my 2004 Renault Megane, also a diesel. I'm no expert, but I know a bit about it as a car enthusiast. I took it to my garage and we changed the ABS control unit. This was because the control unit was faulty. It cost me about 100 euros. I haven't had any problems since the repair. The source of the problem could be similar for you. Can you tell me more about your car? Maybe we could narrow down the problem further. Write back soon!

Hey, thanks for the tip about the control unit. That is a possibility that I will consider. I can say about my Scenic that it has run 24744 km so far and the last service was a while ago. Maybe it's time to have a specialist look over it again. I'll probably have to take it to the garage. Thanks again for the advice!

Hey, no problem! It definitely sounds like an inspection couldn't hurt, especially if it's been a while. The mileage doesn't seem particularly high, but the electronics can still develop some quirks over time. Also see if you can find any corrosion around the wheel sensors or the ABS control unit. Salt and moisture can sometimes lead to contact corrosion that causes such problems. This could also affect the function of the speed sensor. Hope this helps. Let me know what the workshop says!
