So new problem :)

To start with, when opening door, instant pumping to around 48 bar in the accumulator.

Ignition on, "Gearbox Failure" light up on the dash, and sometimes leaves gearbox icon on dash, and sometimes not. But will pop out with "gearbox failure" now and then, until shut off.

Pump is making sure the pressure is kept between 43 and 50 bar at all time.

When trying to read fault codes, nothing shows up.

And im stuck with a car that only will stay in neutral at all time with motor running and not running. Will not even try to engage gear, and then fail..

Read up on alfa forums, and here, and my head is empty for ideas to try now, with what must be considered a working pump, accumulator keeping and ok pressure for the look of it.

Selespeed oil is topped of it looks like had mechanic to do that, but when looking at the retainer where is the MAX at, is where the "container top starts" in the corner of it?
 
Just noticed that with ignition on and car not running, the pump is buzzing constantly. So might be accumulator that need switching, besides the fact that MES shows it at good pressure. Should it prime all time with ignition on? Don't get it. :)

But how the bloody hell, do one get to that 27 mm underneath it. Besides bending a spanner, must be a smarter way.
 
So problem where found, not thanks to MES, which didn't find any fault codes, but Torque on my old samsung 2, found that Brake switch where to blame, for it, so new ordered and should be here tomorrow..
 
Tried your guide and unluckily got 2 broken 27 mm spanners now.. Im no good at bending things apparently, ordered a crow foot spanner and hopes it come soon and fit..

But my stilo don't like the new brake switch still report a failure, but now for sure don't leave a error code, must be a earth problem somewhere. but soon giving up on it and sending it to the open abarth fields..
 
I used a gas torch to heat spanner at point of bend. Some can be quite brittle as you have found. A crows foot spanner will work but may still need chamfer ground on it as shown in guide so it can sit snug enough under the accumulator. It must not protrude below the hex on the accumulator or it will foul the mounting block. You can trial fit it to new accumulator.
 
is the switch special or just stock fiat..? find a good one on a working car to swap..

It's a new one from Intermotor (believe they make em also for fiat original) and adjusted itself perfectly, and I'm only getting a fault on it when trying to run EOL on the gearbox. Before I had it already with ignition on. Will perfectly switch gear with ignition off, but not when running without strange noises believe it need to recalibrate after the 5 years break.

Order this one http://www.ebay.co.uk/itm/BGS-27-mm...796159?hash=item41853633bf:g:u3wAAOSwxH1T5XBT hope it can make a difference

New problem, getting a P1703 Engine shut down from gearbox, because sensor didn't respond, anyone know which sensor, the engine ECU is refereeing to?

Switching gear like it should with engine turned on and off and brake pedal pressed and not pressed.

When moving foot to speeder, and tapping just a tiny bit, it shuts down with the P1703 error code.
 
Just noticed, these parameters in MES, shouldn't they be way higher?

Engine not runnng:

Clutch pressure plate travel 7,410 mm
Clutch pressure plate reference 8,736 mm
 
Just to clarify the trouble that's stopping all progress now:

When starting car, and putting into 1st and tapping gas pedal, engine shuts down with an P1703 engine shut down cause ECU didn't recieve signal from sensor. And trows a quick gearbox failure icon on dash.

1: What sensor is MES talking about not responding?

2: When trying to calibrate EOL in MES, it trows error immediately. (error due to absence of suitable conditions)

Car shift's perfetly between gears with or without engine running, and accumulator is holding pressure fine and primes about every 2 gear shifts. But trying to press the gas pedal everything goes mad, and trows the P1703 error, which is the only fault stored in engine ECU selespeed ECU dont show any faults.
 
I met a Stilo today with similar problems. Two errors in the Selespeed ECU, brake light switch and CAN bus... adjust the switch and clear the errors - then we still get ‘Gearbox Failure’ intermittently and no gears, even though no fault codes come back.

I wonder if the ‘Gearbox Failure’ is the result of a loss of communication between the engine and Selespeed ECUs... the CAN bus has somehow become a CAN’T bus.
