Glove, with a post count of 3 you are not giving us much background to go on. The single sentence trouble description is not much to go on. You have to try a bit harder with more information. 1. Is it flashing ? 2. Is it solid? 3. Did it go on after 3500 and then go off under 3500 rpm? 4. Does it come on right after you turn on the engine? 5. When it is on, is the cat converter hot, cold or luke warm? 6. Does your have have the cats still? 7. Does it have thermal couples at all? 8. What about the thermal couple ecus, are they green or black?
Check through this blog post and see if it helps with any of your symptoms. https://technistrada.com/content/7-ferrari-slow-down-light-explained Slow down light issues are generally straightforward to solve, try the following checklist: Cat temp when it happens (is it glowing red)? If so you have could have raw fuel in the exhaust system and a likely engine misfire. Go to a mechanic. Grounding points for all electrical connections in the engine bay - remove, clean, reassemble. Cat ECU - very common cause. Remove and replace with new. 2 or 3 needed depending on the car. Thermocouples - rarely fail, but it can happen. Results in a solid slow down light.
Thank you for your post. It was very helpful. I haven't changed my ECU's in over 12 years and they seemed to have failed. Will be ordering the redesigned units. Sent from my SM-G935P using FerrariChat.com mobile app
