    First of all, the car is awesome! 2005 F430 w/ clutch pedal. So I'm out on the highway opening her up when at about XXX mph lane change, I get an extended beep and the E-Diff light comes. It comes on everytime I drive the car. Start the car, move about 100 feet and the light comes on no matter what you set the E-Diff switch to. Other that the light, the car runs and drives fine. I'm not sure the traction is functioning any longer either.

    Reading the only other thread I could find, it seems that different ratio tires may cause an issue. Well the front tires are at about 80% and the rears are more like 40%. Could this be a tire wear issue? Car has 3500 miles. Any help would be greatly appreciated. Thanks all.

    I played with it a little today and managed to keep it in race mode for about 20 miles before the E-Diff light came back on. After that it pretty much stayed on. Upon closer inspection of the tires, I discovered that the FR tire has been replace sometime recently. Both rear tires are more like 10% at the center. I'm gonna call my local dealer monday. I hope it's just the tires, which pretty much follows the theme of the other thread.

    Hope you have time for a silly question...just what is the E-Diff?

    Electronic Differential? Electric Differencexxx? Email Diffuser?

    Thanks for furthering my education.

    Will do. I'm gonna make an appt friday. I found out that there was a factory recall on 2005 430's for the E-Diff. Mine was done according to Ferrari. Let's see what happens.

    I want to change the tyres on my 430F1 to Pirelli Corsa (same as on Scud), but have been told that this will cause problems with the E-Diff!

    Any comments on this?

    Cheers

    "The F430 includes the E-Diff, a computer-controlled limited slip differential which can vary the distribution of torque based on inputs such as steering angle and lateral acceleration."

    Tires should not be the problem, It could be alot of things like a CAN line problem could throw it, bring it to the dealer.

    Just got the 430 back this week. It was a failed solenoid. I took it around the block...sideways the whole time!

    The early F430s had some E-Diff issues. There was a series of factory service campaigns depending on VIN number. Some were just some of EV lines and pipes being changed and others even required complete assys.

    Hi guys, I have the same problem on my F430 Spider. I`ve tried everything but every time I hit the rock. I have Leonardo Diagnostic with which I clear all error but after I start to drive the car again the error of E diff appears again. I check the solenoid on the differential and clean it to avoid that the problem comes from it. Please tell me what else can I do to fix that issue. Thanks in advance!

    You will need someone to scan the car with the Ferrari computer to actually pull the failure code. But I can tell you a majority of the time I see the E-diff solenoid part number 205742 fail. Dan from ricambi carries it.

    You can remove the valve, put it in a cup of ATF, and put 12V of power to it and see if it cycles to bench test it.
