Hey guys, I've recently acquired my new to me '05 F430 F1. Before collecting it I did a full service at Ferrari and since then the car has been used just for 500km (50 of them from the workshop for the post service check). When I picked up the car was completely fine but after about 300km the SDL light has popped up, the transmission wouldn't change any gears, the manettino wasn't working and there was this red light on the dash (for a moment I thought it was related to the trunk because it's a weird image). I've already read this problem is related to the E-Diff so if anybody already had this problem, what should be replaced to fix this error? Image Unavailable, Please Login
First thing is to disconnect the battery for 10 minutes- look in the front boot for the battery isolation switch( some cars have them and some dont) using a T40 tork wrench turn it off. Reconnect and see what the car does What do you mean by SDL light- look at the handbook and let us know which one it is, pages 32 to 35
That light looks the the F1 light on the dash indicating something wrong with the transmission or shifting components. I don’t know about F430s but on my 360 I fixed the slow down light by changing the cat ecus (really more of a cat sensor) that was giving false readings to the real ecus I do not know if they went to a different system in the F430s.

What is the status now ..did it disappear Are you able to pull codes Do you have a diag tool Mist likely you fell below F1 pressure levels ..question is why Give me the answers above and we can take it from there Sent from my moto g power using Tapatalk
I had the EXACT same thing, also happened for me maybe 100km after picking it up from the dealership after service..! Just when I bought the car. It was the PIS (Position Indicator Sensor) for me. Unfortunately a 3k euros bill .
The car is fine and the problem pops up randomly - 3 times for now. In 2 cases I just had to stop and restart the car because I was driving slowly in the city, another time I just kept driving constant speed and once I engaged the Auto shifting the problem disappeared immediately. Do you think with a diag tool I can pull the codes even though the problem is not showing right now? Closest Ferrari workshop is 1 hour and half drive and first I want to have it checked at my local workshop.
Just checked the handbook, so basically when the problem occurs I see the F1 Gearbox Failure flash, as well as the orange SL message.
Hard to say.. if a failure happened to a sensor ( heat related ) it would be recorded etc Some pressure related issues like a bad accumulator doesn't set a code usually You are in Italy so not sure what is available to you ..also let me know you level / appetite to do work Based on the answer maybe i can recommend something Let's do some basic timings ..use a stopwatch How many secs does the pump run when door open first thing in morning With key in on position (engine off) how many minutes does the pump stay off When it does finally run with key on how does it run for How many shifts 1 to n to reverse to n to 1 are you able to make before pump runs again ..count how many seconds it runs Now repeat the last three steps with engine running Also check fluid level also The best way is to let the pump run (key on) .. immediately stick your finger in tank and see if they fluid is about half a finger nail Let me know Sent from my moto g power using Tapatalk
There are 1) clutch position sensor, 2) front-aft gear position sensor 3) gear shift plane sensor. 1 is inside the bell housing, attached to the side of the shaft on which the slave bearing slides. 2 and 3 are integrated as one device and attached to the actuator.
Thanks, will keep updated as soon as I'm able to drive the car again, perhaps next week as I don't have enough time right now. I should be doing an hillclimb time attack next weekend and that could be a good occasion to see if the SL light pops up again (seriously hope not!). One thing I've noticed though, I've just bought a CTek battery tender and while installing it I've discovered the battery terminals weren't attached properly and second, the battery charge was a bit down. A friend who worked for many years as mechanic in a Ferrari workshop said the problem could be related to that, he even recommended me to swap the battery for a new one.
If u look on e bay or amazon you will find a digital voltmeter that plugs into the power socket in the consol, if you press start and note the volt drop when the starter engages,, this is good indication to battery condition. Only cheap but you can observe volts
Okay. Just had another look. You know: exactly the same happened to me when I bought the car a day later! Haha. It was the worst. In my case it was the 'PIS-sensor' in the gearbox, the bill says. I believe it's the Position Indicator Switch or Sensor. The part no. is not mentioned, but the cost for the sensor-kit was 350 euros incl. taxes and of course without labour. This is something you might try because your story sounds 200% similar.
Thanks! I asked to clarify for the OP and so I can be sure I did not miss anything with the recent clutch change and other work I have been doing on my 430 Scuderia. As Yelcab said, PIS roughly stands for "Point of Initial Slippage" (it's really Italian) - a parameter of clutches. There is no sensor or switch to monitor or affect that parameter. I would assume your mechanic meant to mean, as you said, "Position Indicator Sensor" - which is called the "Clutch Position Sensor" in our cars. Ferrari P/N 219340 - reference #47 in the diagram (and in the ballpark price-wise to what you mentioned). When they changed that - hopefully they changed the included magnet too. You can see a little detail about that in this video. Image Unavailable, Please Login
Hmm on my bill (it's a Ferrari specialist) it really says PIS-sensor-kit. I'm not sure why I had Position Indicator in my mind but perhaps that was something I misheard. It was two years ago haha. Also just the day after I picked the car up for the first time haha. But if can definitely be the Clutch Position Sensor; I can ask him! Since then, the car has been nothing but perfect to drive and the F1 shifts beautifully.
The Clutch Position Sensor tells the computer where the clutch is at any moment. The PIS (point of initial slippage) is a specific position of the clutch that is programmed into the computer by the mechanic. This position is where the clutch is just beginning to slip from its full engagement with the flywheel.
Right, as previously mentioned this weekend I got to play with the car during an hillclimb and I drove the hell out of it in CST Off - was fun! I did 300km in total and the SD light popped up just once while cruising at slow speed, then I turned the transmission into Auto mode and the problem disappeared in a matter of seconds. So far I've plugged the battery to the tender and I've attached the terminals of the battery properly because I thought the problem could've been related to the battery. I feel like the problem is not related to the battery, bit annoying to find out what exactly causes the light on the car but it's good to see that at least I can make it go away very easily
