Hi guys my dualogic won’t select auto, drives perfect in manual. Any advice would be great as can’t find anything on it
 
Only just noticed this, no longer have a GP, so don't check back often, and I have given up looking at the "one and only..." thread.

Usually electrical, (seemingly more so on a GP than a Panda or 500) ranging from

Spilled drink in gear lever switch

Faulty brake light switch

ABS sensor fault (although usually has ABS light)

Bad earth to rear light units

Water in fusebox

Bad connection in engine bay (ECU and Dualogic actuator are likely suspects, but almost any connector is possible)

Failing earth in engine bay or damaged ECU earth

Or various others of a similar nature.

I have even heard of one which was caused by a faulty Blue&Me module (but could be an urban myth)

Can often be tracked down quicker by getting the fault codes read using a suitable reader. Fiat Examiner or MultiECUScan will do it. Your average garage reader (even the good ones) often won't, (or at least I hope that's the reason for the large number of incorrectly diagnosed "Dualogic" faults, rather than plain incompetence).

Although, as with all Fiat electrical issues, what you think you see (i.e. fault code) isn't always what you actually get - a bad earth somewhere can raise a sensor fault code at the other end of the car.
 
Hi guys I’ve got a p1810 fault code which says clutch system present, I erased the code and auto came back on. I tried reversing and the car slipped into neutral and now only works in manual again
 
What did you read the code with?
Examiner or MultiECUScan will give a description of the fault, usually with likely reasons.
I think P1810 is clutch signal fault, which could be electrical (poor connection) or mechanical (leaking solenoid or physically failing clutch mechanism). However that's only from memory, so please check it.

Unless you have a leak (and/or the clutch is making a horrible noise when trying to get a gear) it is still possibly electrical, and the ECU sees the fault as still present, so disables Auto mode as soon as it is asked to use it.

However, the "slipped into Neutral" bit points to a leak or clutch failure. Need more information about exactly what happened.

I used a foxwell to read it I also had faults for p0500 vehicle speed signal brake node. And p0710 temperature. I removed the battery checked and there are no leaks whatsoever. Put all back together and cleared the faults and now it’s working again but feel like it’s just going to do it again
 
The fluid in the pump is on the minimum mark do I need to add more? Could this be the issue?

Yep, sounds electrical...

There is a depressurising procedure to check the level, and I would advise against just adding fluid. If there is definitely no leak then leave it alone.

The brake node fault you noted in the other post would be enough to stop Auto mode working.

Try to get all modules read using MultiECUScan- someone on the forum may be able to read them for you if you don't want to buy it yourself.

(I wasn't trying to be funny with the other reply, this post was supposed to include both quotes, but had a problem editing on phone. Sorry)
 
Erm I don’t know anyone with a multicuscan I live in Cheshire Warrington. Not sure what’s best thing to do then tbh. What is the brake node
 
And which one is the vehicle speed sensor because that is the fault that says brake node
 
When I reverse sometimes it says transmission see manual. And goes into neutral any ideas guys?
 
Hi
Check the mechanical clutch function, a cracked membrane spring will make it impossible to fully release it, the controller compares the rpm of the motor and the input shaft of the gearbox using the speed sensor at the rear side of the gearbox, if they don't differ enough, it raises the alarm and it won't allow the function intended.
