Well I'm no expert on the TA but virtually all 4 stroke car engines have an oil pump to circulate oil at pressure around the various bearings and drillings to direct oil to piston skirts.
My point is the majority of engines only have an oil pressure switch that will switch when the oil pressure rises above about 7psi. So if the engine is running at a pressure below this it will be ruined.
So my question is does the TA have a more sophisticated monitoring system that measures pressure at different engine speeds and temperature?

.... undoubtedly it will have, such is the nature of the electro-hydraulic control and operation of the inlet valve gear on the TA. What we don't have is first-hand experience of the symptoms, nor had the benefit of the explanation (detailed or otherwise) from the Fiat technician. However, lack of oil/pressure might seem a reasonable theory as to the cause of the problem, if 1/2 litre of oil was reportedly needed before and then further required when at the dealers. If that is the case, then the cause of the oil usage needs sorted and quite quickly. It should ultimately be a low oil user - I've hardly ever had to top mine up in 23,000 miles.

Re: Low oil pressure causing loads of errors

An update!
Just collected car from dealership. Apparently, they put in "about half a pint of oil"! This will be on top of the 500ml I had already put in some days ago.
The fault codes have been cleared.
They were:
ASS U1700-86 Body Control Module (BCM) - Signal invalid
ASS Ul728-87 Controlled Coupling Module (CCM) - Missing Message
ASS U1702-87 Electrical Power Steering (EPS) - Missing Message
ASS U1701-86 Engine Control Module (ECM) - Signal Invalid
ASS U0001-88 C CAN Bus - Bus off
BCM B1052-86 ECM (Engine Control Module) FPS (Fire Protection Strategy) Failure - Signal invalid
BCM B1067-67 VDSM (Vehicle Dinamic System Module) C CAN signal- Signal incorrect after event
BCM U0426-31 Minikrypt error - No signal
BCM U0001-88 C CAN - Bus off
HVAC U1701-87 Engine Control Module (ECM) - (Absent) missing messages
EPS U0001-88 C CAN Bus - Bus off
PCM U0001-88 Engine Control Module CAN Transmission - Bus off
PCM U1701-87
PCM U1800-87 BodyControl Module CAN transmission (only for Trekking application) - Missing message
PCM U0426-63 Immobilizer - Circuit/component protection timeout
IPC U1706-87 BSM (Braking System Module) - Missing message
IPC U1701-87 ECM (Engine Control Module) - Missing message
CCM C2005-68 Electronic Lock Differential (ELD) from brake system fail - Event Information
CCM U0001-87 C CAN Bus - Missing Message

I have no idea what these mean and can't find an online database of them.

Am hoping this is the end of the problem, but I have this niggling fear that it won't be!

Don't see how low engine oil could throw up all these (seemingly) unrelated faults. At no point has the oil level light come on.

Half a pint of oil is not much; it's about a cupful (284ml) and is a bit less than you'd need to bring it up to the top mark on the dipstick from about halfway down. If the total amount needed to bring it up to fully filled is 750ml, then it's unlikely to have done any lasting damage.

No more do I. I'd say it's more symptomatic of an intermittent fault in the wiring connecting the various CAN modules; possibly a bad connection at one of the connectors.

If all they've done is to clear the error codes and put a cupful of oil in, then sadly I'd bet money you'll be back at the dealer before very long.

ignore the prefix,
the U codes are basically bit's of electronic kit on the car talking to each other.. and flagging up errors where they've not received expected answers..
Googling the U codes will tell you a bit more,

so - do tell , how old is the car..and is it still in warranty??.

the oil consumption needs addressing.. mines used less than that "cupfull" in 26K miles..!!

because I used a relevant running in method.

Re: Low oil pressure causing loads of errors

The car has done a very easy 4.4k miles and is only 11 months old. Should never have bought a Fiat?

Re: Low oil pressure causing loads of errors

Hi,
I don't think that your car has had low oil pressure or any engine problem. It's had a electrical problem of some sort that has caused multiple errors on the digital communications (CAN bus) between various modules on the car. This could have been a bad battery connection, voltage surge, loose plug, or even something external to the car like a high power radio transmitter (this is unlikely though). The oil pressure warning was a symptom of the electrical issue. You neeed to wait and see what happens. I suggest you take it back to the garage in a week or two and get them to read the error codes again to see if any have come back.
The oil consuption seems a hit high but not excessive. Low milage can do this as it can take a while for modern engines to settle down.

perfect time to use a break-in method,
to get the oil control rings doing their job,

AND it's doesn't cost anything..!!

Re: Low oil pressure causing loads of errors

At this stage a break-in would be a good hard run under high load at a range of engine speeds. The links below are for new or rebuilt eniges (yes one is bikes) but give an idea of what is going on.

Re: Low oil pressure causing loads of errors

Hi.
Engines last longer when used in different conditions. Low loads and low revs cause the bores to glaze which can increase oil consumption and higher crankcase pressure due to poor ring sealing.
The old age "Italian tune up" is quite correct, a good booting works wonders.

Re: Low oil pressure causing loads of errors

With all those fault codes, I strongly suspect your battery is FUBAR.

I'd second the battery. The dealer was probably right to top-up the oil, and obviously clearing the codes is good, but there's no way that there's that much wrong with the car - if a car fires off that many warnings then it's just saying it's been unable to complete the checks of the various on-board systems - the most usual reason an Italian car says it can't complete the checks of the onboard systems is there isn't sufficient electrical voltage to do so. That's usually down to the battery. Fiat's do occasionally have duff batteries from the factory, which only last a few months before giving up. My Parents Nissan Juke had the same problem with battery, though it only fired a couple of warnings.

If the same thing happens again I'd tell the dealer to change the battery. I'd have thought most Fiat dealers would know this is the most likely cause to be honest!
