I have a 2005 Quattroporte that will go into gear when vehicle is running and when vehicle is not running ignition on it will shift into all gears no problem reverse and drive. There is no fault codes in vehicle. Reservoir have fluid at f1 pump. When opening door it does prime pump. Help please!

Tried the battery disconnect did not work.
To be clear because i think I wrote post incorrect. The car will go into gear with key on engine off. If car is running it will not shift into any gear but make beeping noise 4 i think. Sound like actuator tries to move but does not. The pump does run and system was bled. pressure does buildup in system. Any suggestions are appreciated.
 
When did it last work and what has happened since then? What other problems are having with the car? It sounds like the car is sensing an open driver's door. That would explain the beeping and the inability to engage a gear with the engine running.

Car was purchased in this state. The right fender was damaged along with rh front headlight. No other work was performed besides bleeding of clutch system. The doors are all closed and no message appears in cluster saying open. If I open door it does show in cluster.
 
So, have you ever seen this car drivable?
 
Plugging in with a scan tool and checking for faults, system pressure and carrying out some of the activation and calibration procedures outlined in the WSM are you only sources for answers and progress.

A battery switch cut off and magic rain dance won't accomplish anything with this issue.

But Josh, tonight's a full moon and total eclipse. This is the perfect time to do the magic dance :laugh:
 
After installing a rebuilt clutch, I have a similar problem! I have no reverse. It tries to shift into reverse when requested, and sometimes does when cold, but will only run thu the gears 1-6. No trouble codes. I just replaced the F-1 sensor also. Help!!

Who returned your car to service without all gears working? You shouldn't be asking people here what's wrong, you should asking the the shop that did the work. Unless you did it yourself. If so, did you ever get it hooked up to the diagnostic computer and what did it say?
 
Correction: the car was not returned to me. This was the result from the shop following the install. I was given the option to replace with an OEM clutch or start replacing other items one at a time---the expensive practice I have learned to avoid when servicing exotics. This is a reputable shop servicing only F-1 cars and the dealer is perplexed as well as all diagnostic tests come out clean.

If these problems are not symptomatic of something specific, I will start with installing a new OEM clutch and flywheel. The bearing and F-1 sensor are new. The second thing I would replace would be the actuator.

I have ordered the factory clutch/flywheel and have authorized the work. If anyone on the forum believes these issues could be related to something else, then any input would be appreciated.
 
Well, IMHO it isn't the clutch. The clutch assy spins one direction only. It is also either engaged, disengaged, or somewhere in between. It doesn't matter if the transmission is in a forward or reverse gear, the clutch behaves the same. It also doesn't matter if the clutch is new or old. It should be attempting to engage reverse. If it does, then immediately returns to neutral, I might suspect something going on with the clutch. I'm surprised that the TCU isn't reporting anything to the diagnostic computer when they select reverse and it doesn't react. What machine are they using?
 
I am not sure what machines they are using, however it gives detailed information and allows for clutch adjustment via the keypad.

I suspected the TCU might be a culprit, so I had my friend with another 05 QP switch with his new TCU and the same problem existed. It does exactly as you described - attempts to go to reverse, makes a few soft noises or bumps, then switches to N. This problem started with the rebuilt clutch.

I ordered the new clutch / flywheel and the shop has agreed to credit me the labor for the previous work.

***IMPORTANT***
Here is the reason I suspect the clutch:
1. The problem began when the rebuilt clutch assembly was installed.
2. Reverse gear is aligned in a way to "allow" more clutch slippage than other gears. When your clutch wears, reverse will begin to slip first (according to other F1 owners I have spoken to).
3. With the above, I would think that should the clutch not meet OEM calibration by even a fraction, then it will affect R before the forward gears.

Again, this problem completely vanishes when the car is cold. It is only when the car or the clutch warms up.
 
The TCU is very sensitive in regards to the logic it uses to make calculations and resulting decisions. I installed a rebuilt clutch in a Ferrari ONCE and had a terrible experience. It never worked correctly. I also advise removing that thing and putting a proper OEM clutch in the car.
 
Sounds like they are doing everything right. I've never installed anything other than new clutches in anything, but were did that one come from so we can all avoid your unfortunate situation?
 
Dave, best advice is if you know it's a rebuilt clutch just avoid it altogether. I will say I've had good luck with one vendor which has supplied Kevlar clutches on Lamborghinis. He has some Maser clutches available as well but despite the improved life span, no one seems interested in ponying up the extra dough as it's close to double the rice of a stock unit.
 
Josh, thanks for the insight. Wasn't Pega on here a year or so ago trying to stir some interest in their kevlar clutches? I thought I remembered him saying they would be less than stock. Does anyone know if these are the same clutches?
 
Yea, I don't know of anyone that actually bought one and installed it. The clutches I have bought are made and sold by a guy here in the US whom I've had a good working relationship with for a few years, definitely not the same source.
