Not on the Comfortmatic where the Master/Slave unit (and CSC) is electronically operated via a hydraulic solenoid from the main Comformatic system so you can only move the cylinder piston (equivalent left foot on a manual master cylinder) with the right software. Multiecuscan can do all the necessary procedures.

I know nothing about the Comfortmatic but vacuum bleeding requires no piston movement of master or slave.

Out of interest, where’s the the solenoid mounted. On the slave cylinder?

That's only if you're changing the fluid in the reservoir rather than the stuff doing the real work.

It's part of the Comfortmatic assembly above the gearbox and acts on what is sometimes confusingly termed the Master/Slave unit which is very similar to a manual Master cylinder. There are 4 solenoids in total, 1 for the clutch and 3 to select 7 gears in total:

And separate actuator on the clutch or bell housing?

Another question: when at rest (engine off) is the clutch engaged as per manual, or disengaged?

The separate Master/Slave actuator is mounted under the 2 reservoirs for hydraulic fluid (Dexron III ATF) and clutch fluid (DOT 4). The Master/Slave cylinder acts on the Concentric Slave Cylinder CSC in the clutch bellhousing.
The clutch is engaged when the engine is off in exactly the same way as the conventional manual transmission. Everything inside the bellhousing is the same between a manual and Comfortmatic clutches

That's not how vacuum bleeding works. Vacuum is applied to the slave bleed nipple and draws fluid from the master which is replenished as required. It's how I change my brake fluid and disturbs no settings and doesn’t require movement of any pistons.

Adams Morrey Southampton fixed mine last year. It took a couple of attempts, as they thought it was fixed by draining, flushing and refill the fluids. Then on test drive the slave cylinder pissed fluid all over the clutch

Which is why I enquired as to the position of the clutch at rest.
I would have thought that you can draw it all the way through to the slave, but dunnah01
Says otherwise.
I really must spend some time sussing it out some more

You can draw the clutch fluid through by vacuum bleeding but you run the risk of pulling ATF past the primary chamber seal into the DOT system if the cylinder piston isn't fully returning against any residual hydraulic pressure so not something I would do.

I couldn’t work out why it wasn’t possible. You have just explained it is possible, and why it’s not recommended .

I assume they now know what they're doing... I would add though that perhaps 'some' of those there didn't understand, as from what I've read in earlier posts, one of the bosses does his own motorhome every year as a preventive/maintenance measure

 

[Just smiffy]

I just think it’s a shambles that fiat don’t know how to fix the vehicle that they make….

This thread seems to be going to run and run which is more than a comfortmatic

It's worth noting that Adams Morey have a number of branches. Only some of them have s motorhome department. Only one of them , Portsmouth, has a service manager who has a Comfortmatic motorhome. Their other branches, whilst capable, may well be on different learning curves.

Thanks. I was about to book the Southampton branch this morning after telephone call yesterday, will now book with Portsmouth!

Pretty sure they would talk to each other but to be sure

I'm not sure how relevant this is but the latest edition of Which magazine mentions the Consumer Rights Act 2015 and that up to six years [ five in Scotland] if goods do not last a reasonable length of time you may be entitled to some money back. Might be worth mentioning this legislation in any correspondence with Fiat .

 

[rayreynolds7@g]

Don't let the garage change anything mechanical or electrical unless it is obviously broken. Ask them to do a 'clutch self calibration enable' routine first . If they laugh or look blank move on to another garage.

Hi Funsters,

Could someone explain how to perform the clutch self calibration routine....Do you need some kind of gadget ??

The sun is shining so hope everyone has something planned this weekend..

 

[MisterB]

Adams Morey at Portsmouth have just quoted £240 to change clutch fluid and engine oil and filter ...

I am booked in early June - thanks Rob for sharing your issues and how they were resolved

[WESTY66]

I feel Adams Morey might be picking up some extra work due to this thread, considering a trip myself

 

[jaygee]

It is

Have to agree. Our new Adria Sport has one of these

Although i have booked it with Adams Morey, i am sure there are lots more competent companies out there, its just finding them!! perhaps if anyone knows of any they could post on this thread or even consider starting a new thread for recommended garages that will do the clutch fluid change and recalibration, BUT only if you have personally had the clutch/brake fluid change and were happy with it !!

Been suggesting this for a while

Any dealer should be able to do it.

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.

The dealer needs to be confident that there is no air in the clutch hydraulic system as it is possible to blow the new CSC seal if the Master/Slave pushrod is allowed to travel to it's full extent.

 

[TheLifeofBrian]

So, broken down again!
The lid was loose on the hydraulic fluid reservoir & some of it must have sloshed out!
I have topped hydraulic fluid up & it's taken about 250/300ml. If I turn ignition on & select gear it goes in and out ok & I can hear hydraulic pump running every few changes. I have done that lots of times to get the oil through & topped the fluid up after the first time.
If I start it in neutral and quickly put it into gear there is a big clunk & it goes in. I can then select neutral afterwards.
If I start it & wait, as soon as I try to select a gear it says 'gear not available'.
I've tried disconnecting the battery & leaving for 30 minutes but just the same.
Any one any ideas please ????????

I’d say that’s reasonable as I believe the engine oil isn’t cheap.
