Granturismo F1 Stuck in Neutral

Hi, I'm hoping someone can help....I've read loads of threads for pointers but have not managed to resolve this problem.

I bought my 2011 Granturismo MC Shift last year. The garage I bought it from had the clutch replaced (I have the receipt).
I recently bought the Larini sports cats and and X-pipe. I fitted them and drove it but wasn't keen on the change in tone so replaced the X-pipe back to original.
To replace the exhaust, I put the car on 4 ramps, so it is level and easier to work under.
When I changed the x-pipe back I also disconnected the battery for 30 mins to do a reset as the CD player was being temperamental.
After finishing the exhaust, I lowered the car down again and attempted to drive off but it is now in Neutral and will not go into reverse or first either with the engine on or off.

I've since bought a Launch x431 and have bled the f1 system at the quick release (with CHF11S), which seemed fine. I also attempted to bleed from the valve at the bottom of the bell housing below the clutch but nothing is coming out of it (which seems odd).
I've also run the Autel Ap200 which shows the circuit pressure at 44 bar normally and I can hear the pump working when I open the door etc and it doesn't run for more than a few seconds. The 'clutch actuator sensor' is showing 0 bar though (I suspect this is not what it should be).

I've also changed the relay and run the gearbox calibration (I think thats what it was called) through the x431. I can hear it changing gear during this but the process said that it failed.

Before I somehow get it to Maserati, I wondered whether anyone would have any ideas for what's wrong and what I could check next?

Many thanks, Matt

Thanks Phil, ok, is that the bleed valve under the clutch? If so, is there any reason why nothing would come out even during attempts with the system bleed using the x431?

It should definitely bleed at that point you need someone to keep the reservoir topped up that's for sure.

Well I've tried again, the rear one is working fine with fluid coming through (no air), then trying the front bleed and it's not pushing fluid through (or even any air) during the bleed process using the x431

It seems very odd that everything was fine until you put the car on a ramp. If there was air in it before, it wouldn’t have worked then either.

This suggests to me that something is affecting the solenoid which operates the clutch and isn’t related to bleeding. I would be carefully checking all wiring and pipe for damage.

I presume you didn’t take the rear boxes off to change the x-pipe. I know you can use a strap to ease the x-pipe back to get the pipes out/in. How did you create enough room?

As Zep says, seems a bit of a coincidence. Would seem quite likely that you've disturbed something under there.

Thanks for all your help guys.

After your advice I had a wider look at everything under the car and found that the connection from the gearbox to the clutch wasn't fully closed (I guess I must have caught it whilst messing about with the exhaust).

Once it was pushed closed I was able to bleed the front valve and it all seems to be working now (it changes gear on the ramps manually and through the learning program with the Launch).

I've just got the gearbox oil to change whilst its on the ramps and hopefully I'll be able to drive it next week. Thanks again:).

Brilliant. Good work getting that fixed.
