My mechanic is still searching for the cause of which one is draining the power within that F39 fuse ( this is the fuse that draws 0.170 , battery dies within 6~7days if left stationery ), which shares radio bluetooth, or EOBD diagnostic socket, or volumetric alarm ECU , or alarm siren ECU .
Have done all checkings, such as alternator, new battery, no lights left on, etc and none from the usual suspect.
The following symptoms on my car-
-Flashing odometer
-Missing menu options
-Steering wheel volume button works sometimes
-blue n me none whatsoever, cant update, pairing, window button no response

Mind you, we only had the car 1 month, and only use it 2 times a week, although i am very cautious about how to observe my car faults , Thats why the sold vw golf had no problems with the same care.

Please help if anyone comes across with this type of electronics problems, thank you.

Hiya, How old ids the car, and what version, petrol/diesel ?
Cheers Qube O.

PS, Welcome to the forum.....

Was it a private sale or a dealer? If it was dealer of any sort you have rights and should go back to them to get this sorted.
The flashing odometer indicates a CAN bus issue. I'd suspect the radio or Blue & Me unit.


Robert G8RPI.

14 plate, 80k miles though.
Diesel multijet.
We suspect the previous owner sold it because she cant find the fault, the battery was fairly new, 1 would change the battery first, but we have checked all and now my mechanic may withdraw as he doesn't want to charge me while it taking awful long to locate the hidden wires, according to him, these Canbus wiring makes it difficult.
Pls help.

Robert G8RPI,

My mechanic did mentioned it could be the wiring for the radio because of Canbus type, but not the actual radio unit as i unplugged the radio and something stil drew power.
I love to diable the Blue n Me if that's the cause, is this a good idea?
Many thanks, and its a pleasure to join this unique group of enthusiasts!

Robert G8RPI,

It was private sale, i tried to contact the previous owner on several attempts , she never replied.

May be worth starting with the simple things......known Qubo faults which cause all kind of electric gremlins.......1st, the rear light in the luggage section, the switch, built into the door mech' can stick, leaving the light turned on.......difficult to see. 2nd, the rear light clusters have been known to get grotty/crummy terminals on the connectors.....causes all kind of grief, and 3rd, (this one is silly), the brake light switch can fail/short, even though it may still operate the brake lights............may be none of these, but hey ho, I've had all of them on mine..........

Qube O,

How you dealt with them 3 issues of yours?

Thanks!

Where are you located?
It sounds like you mechanic is not used to modern cars. My next move would be to plug in diagnostics like Multiecuscan (www.multiecuscan.net) and see if any of the modules on F39 are missing or showing a fault. Ifthey are it's likely they are faulty or there is a wiring issue connected to them.

Robert G8RPI,

I am in St Albans, Herts.

This mechanic actually Fiat trained before running his own shop.

He did come across with Fiat wiring faults in the past, stating design flaw.

He did plug-in with his equipment, a long list of codes, he deleted them all, yet those came back , thats why he is suspecting that Fiat Canbus wiring.

I was hoping to find a known cure and relay it the mechanic, at the moment, this seems like a 1 off?

Thanks.

A bit far away to come have a look (I'm near Cambridge). It could well be a short circuit on the CAN bus system, either wiring or in a ECU. Rather then looking at specific codes it can be useful to see if any ECU's are "missing" from the bus. Unpluging a missing unit will let the others work properly if it's an internal fault. Failing that giving a clue, it's time to get an oscilloscope, ideally Picoscope Automotive, on it a see what is going on. Bigges problem I'd have is getting the wiring diagrams, elearn does not seem to be available for the Qubo.

You know your car, in depth!

I will show your view to my mechanic, so how exactly does it work with your way? Can you fix it if it is how you see it?

Thanks

New hatchdoor/lock/switch assy', new brake light switch, and remove the rear lights, (simple to do), and really clean up all the terminals/connectors. Problems encountered were, haphazard warning lights on dash/failure of various electrical systems to work, flat battery, made no sense, and no fault codes except for the brake light switch.
These faults occurred separately over I guess a two year period..........
Hope you get it sorted.
As a point of interest, I'm not the only Qubo/Fiorino owner on here to have had these faults.................

Thanks for the info, dont think mine relates to your issues, but it definitely is a know how for future encounters.

I certainty hoping to gather as much known and resolved mechanical issues here from Qubo/Fiorino owners , its a community where we can share n help.

Thanks

Had some PM's from Zron on quiescent current draw. He is seeing 180mA (0.18A) while my Croma Eleganza only draws 25mA.
With a fully charged 60Ah battery the Qubo would only last 14 days, not good. The Croma would last 31/2 months.

Water in a plug,socket,connector ? Causing carbonisation of plastic and surface leakage .???

Michael Dranfield,

Hi,
Thanks for your suggestions, at the moment my mechanic has checked with his diagnostic machine and came back clueless as one can imagine to perform thorough checks at every single plugs, sockets and connectors is a mammoth job that unles its worth his week worth of income, to which i cant possibly afford to pay him, at the moment, he is checking whats available on the surface, spent the odd 10 mins here and there over the course of 4~5weeks so far..

This is where a wiring diagram would come in handy, however what I would check are,if removing the said fuse stops the ,170 ma drain it's pretty safe to assume this the right path to start the search,have a look in your hand book what of the cars systems this fuse is protecting,if as you say it's possibly the ECU then check out anything connected to the ECU that could be exposed to water ,if you remove the ECU connectors water ingress is usually given away by green or white deposits on the connector pins, if the fuse is protecting a higher current circuit such as the electric windows have a look for any wiring that is exposed to physical movement such as the loom connecting the body to door as repeated opening and closing can cause insulation of the wires to crack and short together.

It would not be to difficult to try and diagnose yourself without paying a mechanic buy a cheap multimeter set it to read current and place it across the fuse holder with the fused removed and then unplug items one by one untill the current flow falls away.What is the amperage of the fuse you remove to make the fault go away ?

Also have a good look under the bonnet,are all the wiring looms properly clipped down,do you see anything that may not be clipped in position which could be subjected to mechanical vibration that could be rubbing or chaffing onto a metal surface,any wiring running near the hot engine will soon go brittle and vibration could cause a short .

Hi Michael Dranfield,

It is Fuse F36, 10amp, for the following ~
radio bluetooth,
EOBD diagnostic socket,
volumetric alarm ECU ,
alarm siren ECU .

The mechanic said the last resort is to send the ECU away to be diagnosed by some company who has the expensive equipment, and that would come at a price, but at this stage he is unsure, i would very much like to DIY, the name ECU is quite remote to me, can you throw me some clue where is the likely place out of the above mentioned 4 electronics, where is volumetric alarm ECU and alarm siren ECU situated?

i totally get your clue about the green and white stuff on copper, my mechanic did mentioned definitely not EOBD diagnostic socket, i think because the socket is visible where the cabin fuse compartment is, he suspects its the radio unit not original, it looks the same as original, i cant be certain as only had the car for 2 months, i have installed a Kenwood unit anyway.

I will check again whats anomaly in the bonnet, one thing worth mentioning , there is a kind of socket right under the oil filter cap is, and its cover with black oil, i imagined its from previous oil changed dripped down, pin pointed this to my mechanic, he is adamant that not to worry , but i have doubt, simply because oil in the socket, he said oil is a good protectant.

Pls advise, thanks
