Technical Comfortmatic issue Help

[MSjoberg]

Glad I found your comment on this thread I can delete my thread now asking for information on the multiecuscan
I’ve just changed my clutch fluid but got another one to do has was told to do one then another after 100 miles
How ever I manually bled my clutch but want to try these things with multiecuscan I’ve ordered today

So this process with the bleed how is this done mate any idea ? When bleed activated do I suck fluid from bleed nipple or small res tank

I’m wanting to carry out a few things while got the software like gear box reset and calibration etc

The clutch drain procedure in MES performs 15 (I think) clutch open/close operations which should bring out any air in the hydraulic oil lines and EV 0 solenoid valve.
Bleeding the clutch DOT4 system is something else, I don't know of any other method for this than manual bleed.

I have no idea about how it should be done. It was like 9 years ago, so I remember the friend saying a precise order was needed for the operation to be successful.

Have you checked both service manuals of the x250 available here in the download section of the forum?

Software update I’ve read is a good one which fiat will do
But all mentioned above they won’t do unless you have the clutch changed with them

But I’m getting told to carry out some because they all do help the comfortmatic run better give it new data

Thanks yes I’ve just done the manual bleed mate
So this other procedure you just carry out in mes nothing hooked up to bleed ? Just confused how it can get trapped air etc

Correct, it probably will not get any trapped air in the DOT4 system out, it will just be pushed forwards and backwards in the pipe.
Air in the hydraulic oil system is easier to get out, because that system has a circulation back to the oil container.

Ok brilliant now I understand
This is what confused me because I thought it was another bleed procedure has in fluid out once activated lol

 

[Seanwinder22]

Here’s what I’m wanting to do
adding hydraulic oil and gravity bleeding the clutch.

1. Run the 'clutch and electropump replacement' routines in MES to reset the Transmission Control Unit (TCU) electronics.

2 Run 'actuator base adjustment' in MES to setup the hydraulic and clutch units.

3. Run the 'clutch drain' routine in MES to ensure there is no air in the clutch system.

4 Run 'clutch self-calibration enable' in MESto fine tune the clutch actuation to engine specific behaviour.

One more thing I found interesting in the eLearn module:

APPLICABLE TO VERSIONS WITH: Robotized gearbox

- After having bled the system using the special equipment, connect the Examiner diagnostic equipment, enter the active diagnosis ambient and carry out the operations listed in the specific procedure for bleeding the air from the hydraulic clutch system.

Keep the brake pedal pressed down throughout the operation.

The 'special equipment' is 1.806.097.000 - Device - Bleeding brake system air, a vacuum bleeding tool.

Thanks even more confusing again lol this is what I’m talking about I didn’t think you just sit in the van and press on the laptop bleed system and wait ? reason I asked
I thought you would set up the tube device like the manual bleed but get the mes to carry the pumping sequence
I definitely need to look further before plugging in and pressing go

Here’s what I found
including adding hydraulic oil and gravity bleeding the clutch.

1. Run the 'clutch and electropump replacement' routines in MES to reset the Transmission Control Unit (TCU) electronics.

2 Run 'actuator base adjustment' in MES to setup the hydraulic and clutch units.

So reading this is does say bleed air out

I think you can do a manual bleed or computer
The bleed is done
I think drain does mean trapped air out

Yes I think you use the special tool for clutch fluid change bleeding the computer way or manual once done
The mes settings again do the clutch drain to maksure no air left in the system I’m guessing

And a couple lines more from the aftermarket service manual by Buchel Verlags AG:

Bleeding the clutch control circuit

Immediately collect leaking brake fluid and flush the area with brake cleaner.

Avoid contact of brake fluid with eyes and skin. Wear protective gloves and appropriate glasses.

It is not recommended to bleed the circuit without a suitable device. The way the cables are routed and the low capacity of the pump require bleed under pressure or suction through the bleed valve. When bleed it is necessary to ensure that the reservoir is not emptied and that no air enters the pump.

■ Connect a suitable device for filling and bleeding the brake system. A flexible bleeding hose should be used for bleeding.

■ Connect the flexible bleeding hose to the fluid collection container in the brake bleeding device.

■ Remove the air vent valve cover.

■ Place the flexible hose on the actuator's air vent valve.

■Supply the circuit with a pressure of 100-200 kPa using the bleeding device at the fluid reservoir.

■ Open the air bleed valve by turning

it about 1/4 turn.

■ Drain approximately 100 cm³ of brake fluid.

■ Close the air vent valve.


Cars with robotized gearbox:


Adjustment of the clutch control circuit can be done depending on the tester and software status by testing the actuator. However, engaging and disengaging the clutch is often only possible by engaging a gear with the engine running. Bleeding is also possible without performing this operation.

Applies to all cars

■ Check clutch operation.

■ Conduct a test drive.

Oh this is shared brake / clutch mate
Comfortmatic has its own clutch res separate from brakes which I understand it has a device to do all brakes / clutch etc

Yes I think the small clutch reservoir can get bled manually or gravity assist with computer
Then another program to help trapped air etc rise to the top of chamber
Which mes can do all mentioned I’m reading
It’s confusing

 

[Seanwinder22]

Ok here we go
Clutch calibration

This procedure is used for the fine calibration of the clutch. It must be performed if the actuation unit and/or clutch assembly is replaced, if the clutch engages and disengages in an uneven way and if the gearbox control unit is replaced.

The following is necessary for proper execution of this procedure:

- engine temperature > 80°C

- clutch temperature between 20°C and 150°C

- no errors

NOTE: The procedure must be performed in the following sequence:

1. Press the Execute button (engine must be OFF - Stop&Start function not active, gear in Neutral)

2. Start the engine

3. Wait! The control unit will perform 5 clutch activation cycles! It should finish in ~1 minute.

4. Turn the key OFF, then wait at least 15 seconds and turn the key to MAR.

this example is for 2.3 x290 others may be different



-

If you have a catastrophic component failure and mechanical works need to be undertaken then it is necessary to perform some routines to safely undertake the works and then setup the system once reassembled.

Multiecuscan (MES) has all the necessary routines.

You need to run the 'accumulator depressurization' routine in MES to safely reduce the hydraulic oil pressure in the Comfortmatic module before any works are undertaken.

Undertake the mechanical works in the same way as the manual gearchange. Gearbox out, change CSC, clutch and DMF (if necessary).Reassemble everything including adding hydraulic oil and gravity bleeding the clutch.

1. Run the 'clutch and electropump replacement' routines in MES to reset the Transmission Control Unit (TCU) electronics.

2 Run 'actuator base adjustment' in MES to setup the hydraulic and clutch units.

3. Run the 'clutch drain' routine in MES to ensure there is no air in the clutch system.

4 Run 'clutch self-calibration enable' in MESto fine tune the clutch actuation to engine specific behaviour.

 

[Seanwinder22]

Disconnect battery to ensure no priming can occur during fluid replacement.
Gravity change hydraulic fluid via CSC bleed screw.
Reconnect battery
Run clutch relearn procedure in diagnostics to bleed any air trapped

I'm not saying it isn't. As far as I remember there was also some confusion in the original workshop manual (eLearn), which was pointed to me in one thread here. I was very close to buy a Comformatic diesel, but clean exhaust gases were my priority, so I've bought the red green one, with manual transmission. So I don't have any experience nor even a possibility of check how the Comformatic looks like in reality.

The only I can do is paste information I can find on the internet and my non factory workshop manual.
