Help Needed...Car will not change gears.

So i think we had a breakthrough on mine over the weekend, we set up the F1 system having removed it from the car onto a test rig and cycled through a number of programs and found the following problems:

1) Solenoid EV2 was giving low readings, all remaining solenoids were pushing 110psi+, with EV2 running 69, we then replaced all 6 solenoids and they jumped up to 130/140 psi, but EV 2 was still low at 89
2) We then found the EV1 pump line was crimped & this was reducing the PSI into EV 2, this was also replaced and pretty much seemed to resolve the issue & was cycling through all the gears with good PSI to all solenoids
3) We think the combination of a slightly dodgy solenoid and the crimped pipe was struggling to get the actuator to the right position to select the gears insitu

The system will be refitted today back on the car and fingers crossed it resolves the issue fully

 

Massive thanks to Simon at SS Autotech for what i hope is a great job and working through these gearbox issues on my car.

 

Seems like these guys know what they are talking about, taking a structured approach to each problem and systematically working through each of them until you find the fault at hand.
Hope that London Paris gets his car sorted soon, i feel for him!

 

Great news! Glad it is coming together.

 

Sorry to hear about what’s happening. Hopefully this will be behind you soon enough. Regularly telling all of us what’s happening is well appreciated, that’s why this Forum and its members are great.

 

Even if I bought a Cali30 last year (loved by both my wife and I), I still have an itch to add a V12 4-seater. Does it mean that long-term it’s much better in terms of maintenance owning a 2005/2006 612 (not an OTO)? Easier life it seems. I love the 612 design (the FF too but afraid of the PCU situation).

 

I'm dreading the bill though, its had pretty much new everything except a gearbox at this point, the only good thing is the Indy broke it (not sure how) so hoping the labor will be generously discounted !

 

Good luck, its bloody frustrating !

 

I hope the dealer has someone there that still remembers how to use the SD3!

 

Yeah, the guy at the dealership still needs to remember how to hook up the SD3 in "pc mode". I had an SD3 for a while - you can control it on the device itself, or run it over a computer. I'm sure they'll figure it out, its just really old tech now.

 

It is sad to say, but if your Ferrari is more than 10 or so years old, you are on your own. Ferrari doesn't want to know you after that.

My 2008 612 OTO had a transaxle line rupture. There was no part available anywhere, not in the US, Canada or Europe. Fortunately my independent mechanic got the part manufactured and no surprise, it was better than if I had sourced the original part from Ferrari.

Fortunately this was a mechanical part which was easily fabricated. When it comes to electrical parts I might not have been so lucky.

 

Ouch and I am sorry to hear that.

I have an issue I have been avoiding/neglecting/ignoring (choose one) but I do need to get fixed. I have already resigned myself to it being 5 figures. The only question is where in the 5 figures it lands. It could be relatively simple but when the code doesn't exist in the SD and they need to contact the factory, I am assuming it will go WAY off the rails as we dig into the issue. But that is another thread.

 

Yup; both are CFC301F hardware. The only difference is the firmware loaded onto them.

I have a friend who thinks he is able to help... can you confirm what the precise symptoms are? I understand that:
- the gearbox light is on?
- there are no fault codes stored on the TCU
- the car is stuck in neutral and will not engage any gears
- this all started when the dealer used an SDX tool to carry out the gearbox self learn?

I assume the gear indicator is correctly showing "N"? Does the F1 pump come on when the door is opened?

My pal said he had this exactly the same issue with a car serviced by a Ferrari dealer in Egypt. He was able to fix the problem when they sent him the TCU, which I have to believe, as he's a seriously talented guy. He's saying the isue relates to a software bug in the SDx program that causes something in the TCU to get scrambled.

 

Perfect - he says that this is exactly the symptoms he's dealt with before. On 4 cars now as it happens, all where an SDx was used to set the PIS.

He has just said 3-4 days to turn around from when he receives the TCU.

 

I hope you will have good news to share.

 

That glass will be a bubbly one once you get your 612 back on the road Bill! Thanks for continuing to share your experiences and educating us all. V12 SUV?
