Ediff failure light

Did you say $15k for an F1 pump?

 

LOL!!
I cant believe this prices man!! How can people come with this numbers????
I think that when these guys see Ferrari owners enter to their shops they just pull down their pants zipper and let the party begins!! LOL

 

That's what I was thinking! Steve, I would have your car looked at by another dealer as they obviously don't know their ass from a hole in the ground.

Just FYI, the F1 pump, latest version is $800 for the part and it takes an hour to put it in and bleed it via SD2-3.

I have a friend who had our local Ferrari Stealership tell him that he needs '3' tires? Since when do they make cars with three tires....Lol. It really is sad and not good business practice. It's been put very well by others on this forum, be honest and have customers for life!

 

Why don't we try to help this guy instead of dancing on his misfortune... That's why he came here.

So, let's get back to the subject and see if we can give him some advice.

For one thing, you can try an independent shop. The pump might be gotten for less in the aftermarket. You might want to contact Daniel at Ricambi and see what he has. I would at least talk to an independent shop before doing much else.

I think the dealer did try to help you here as best they could. They tried it seems pretty hard to get the car working at no cost to you. That isn't working and now it's time to take it to the next level. If changing the the obvious things don't work, it's got to be deeper. Deeper means more expensive.

These Ediffs are actually pretty reliable (there's not many threads like this one) so it's more likely something like the sensors, the pump, or the actuators that's causing the problem. There's a problem here and there with the warning light but it's usually a pretty simple fix as the dealer tried.

If in the worse case the E-diff needs to be replaced, it's going to be bloody expensive. There is no other way around it.

Let's hope it doesn't come to that.

The only thing I don't understand is why the dealer cannot diagnose the problem better for you. It would seem they would be able to single out either the pump or the edif in whatever data they have about the systems.

 

Is it the same pump for the F1 that feeds the Edif though?

Remember he's talking about the Ediff light, not the gearbox. The gearbox appears to be working perfectly.

I do agree with the second opinion though.

 

+1 Mayor. You were the one I was thinking of when I was writing my last post.

Per the Edif, from what I have come to understand its the same pump that feeds the tranny and Edif. Either way, it won't be $15k for the pump, I can assure you.

 

Yah I agree on the cost of the pump. I would shop around.

I'm really surprised it's taken this long to get this far though and by the lack of information/speculation on what the problem may be.

If it were me, I would be upset about that aspect here, aside from already being upset about the problem in the first place.

I also would not pay the previous bill of $7500. The problem wasn't fixed so why should I pay for that? I think it's their responsibility to diagnose and fix the problem. It depends a lot on the documentation that was signed and agreed upon when the car came in. The six month gap though between their fixing it and it returning though may indicate that there were more than one problem. It's iffy who has the best case here. I can see it both ways.

But, that's a separate issue altogether. What's more important is to get the car fixed at the least amount of effort and cost.

 

Glad I wasn't the only one thinking this.. $7500 for what? Seems unreasonably large..

 

You can bench test the soleniod with a 12v battery. Dip it into a container of diff fluid and you should see air bubbles when it starts to pulse. That is the first thing to look into.

If the pump failed they should be able to get a pressure reading off the SD3 computer. If it failed it's not a big deal to replace or expensive.

If both check out I would check the CAN network for faults. If the soleniod was shorted out or damaged it can short out the CAN HI or Low network including any computer that is connected. Normally it would damage the E-diff computer first but can travel further down the line.

 

The OP is in Fort Worth TX. Anyone have a recommendation for a shop familiar with the 430 E-diff?

 

Maybe he should ship car to LI to Bradan for the fix. Even with shipping costs it may be cheaper and done right. I really liked Bradan's above post.

 

+1; It may sound crazy, but paying a few $k for round trip transport to Bradan is not as crazy as it may sound. They can also do a paint correction while its there.

+1; on trying a second shop, make sure they have one of the service computers: SD3, Leonardo, etc

Me personally, I would read the workshop manual, learn the system, and fix it myself. If I fail, I would send it to qualified mechanics with more experience and better test tools.

 

I just read this thread and am shaking my head. At this point I would have no confidence in your Ferrari dealer service department. Furthermore I would not rely on the hearsay of what FNA reportedly "advised." The car should go to someone who you or someone you trust has reason to believe will zero in on a small number of possible causes based on what you know to date.

I think the best thing this thread can do is suggest such skilled trustworthy service centers. Maybe Bradan can recommend one or two based on their knowledge and experience.

 

+1. If you're going to have to "throw parts at it", you can at least try working used parts with this method.

That's disappointing that the stealership handed you that line. That's unacceptable as is the $6000 for not solving the problem IMHO. I'm sure it's not indicative of ALL dealerships, but this fleecing is IMHO not acceptable.

Actions like above is the mark of a reputable mechanic.

 

I had repeated problems with the ediff on my F430 as well. Mine would fail after driving it pretty hard on the track. There would be no warning light, just a red ediff failure light after slowing down and exiting the track.

I took it to FoH and they said it's very important that the ediff valve has to be tightened precisely.

It hasnt failed again, but then again, Im too scared to take it out to the track lol

 

With the OP permission, I would like to share, as they say " The rest of the story " as what has been presented here is less than accurate. Or rather less than the complete story.

Thank you for your thought out and considerate reply.

I will await a simple yes or no from the OP before adding more information from "the other side of the desk".

...he certainly has earned his reputation, so have some dealers....

 

I think what's important here is not who did what or why. There are always two sides to any story. And, both could be right depending on your point of view.

That's not what's important.

What's important is what is the proper next step the OP should do to get out of the situation and his car back on the road where it belongs.

 

Yes but if everyone (myself included) would adopt this view in life then there would be no drama on FChat. And then the world would be a boring, homogeneous, happy place...

 

Well, I have also been told many times that I should take my own medicine.

 

I am looking forward to this!
