Hi everyone, I'm considering an 05 430. Naturally I would get a comprehensive PPI. Owner has indicated experiencing random slow down lights (F1) that clear with a car reset. The F1 system hasn't been bled since 2010. The car also needs valve cover gaskets and we'd do plugs at the same time. I'd end up covering the costs of those repairs. I guess I'm a bit apprehensive as I don't know if the above would truly solve the slow down lights. Even after the above maintenance, with the lights being intermittent, there would be no way to know until I take receipt of the car and drive it. Looking for any opinions. Huge concern or am I making too much of it? Many thanks, Steve
The Slow Down light is not an F1 light. They are different and look different so your post is a little confusing.
What is the reason why the seller hasn't taken care of those things? Seems it would be a logical thing to do if they want to sell the car. Also, PM me.
This is my ignorance. I've been searching the forums so much, I may have confused myself. Just slow down lights? I read where those could come on with F1 light? I assumed since an F1 bleed could rectify, that perhaps they were related. Steve
Usually slow down light is the temp sensor in the exhaust tells you that it's too hot and you're going to melt the exhaust system. On a 430 because they rarely fail, and so it would run that hot is either due to prolong hardcore track driving with little ventilation or maybe something deeper such as the engine running out of parameter and is way too lean. I would be concerned because you will need a deep dive into the system and codes, check multiple system to make sure it's a bad sensor and not a sign that a part of the air / fuel / ignition system is failing Sent from my iPhone using Tapatalk
E-diff light is not a slow down light or an F1 light, that the op mentions. Codes should be evident upon scanning at any good Ferrari service shop.
Only way to know is to get a scan to see whether the slow down lights are real or not. I have a 360, but i had to replace one of my exhaust temp ecu's, the system was shutting down a bank of cylinders. I measured the temp of the manifolds too see which one was older and then confirmed with a scan. Easy job, and I would assume the 430 is similar.
The 430 did away with the exhaust temp ecu. It's all integrated into the main ecu, so we don't get the same faults in the 430... unless the whole ecu goes kaput Sent from my iPhone using Tapatalk
In another forum, a 430 owner with a similar slow down light posted the following: "Just got back from dealership. Apparently it has to do with the F1 pump losing pressure during rapid up or down shift successions. Something with a solenoid leaking." and "Just got it fixed, apparently just loose bleeder screws in the gear box letting small amounts of air in." Another poster's response: "Yes, that's a common problem often overlooked by tech's so your guys sound like they know what they are doing! There are 3 screws located under the actuator that work loose and cause this issue. Also, early 430's where fitted with the same pump as the 360, which couldn't manage the extra load of the e-diff system on top of the f1 so often failed. Early cars can be retro-fitted with the later pump, and 360's can be updated using the later 430 pump with small alterations to the valve block bracket and feed pipe."
Yeah, the Slow Down light is due to an overheating exhaust/catalyzer. On my 360, it was the sensor that went bad, causing this message to be displayed. The sensor was cracked and got replaced, and my warning message went away.
Red Slow Down light indicates - high temperature in the exhaust system Yellow Slow Down light indicates - temporary malfunctioning of the electronic differential
Take it to a Ferrari for Pre inspection and they'll tell you what' going on with the car. They are the expert It's worth the investment so you know what you're getting yourself into. I DID and it's the best $600 I spent
I have had the amber slow down light on my F430. With the same reset procedure by restarting the car Ferrari dealership replaced the E Diff solenoid and bled the system, never had an issue since. Its been covered in an old thread of mine.
To the OP, these issues wouldn't stop me as long as it's properly discounted from the market price of a good condition 430.
I think you should be asking yourself "why am I thinking about buying a car with a known but unresolved issue of undetermined expense?" If you come up with a good answer, then go for it. At this time of year, there'd better be something special about it, or the price.
