Yes, especially since now replacements for these ECU's are simply unavailable!!

The auto electrician in Glenrothes [Daryl Murdock of Daryl's Auto Electronic 01592 774342] who replaced our ECU 2 weeks ago said [as an ex Service Manager with them], 'Bosch Batteries are not the best; Tools, yes, but batteries , 'No'. I had decided to replace the 2 week old Bosch with a new Yuasa, and the electrician said he would have recommended this brandIt is a Bosch powerframe technology, which is supposed to last up to 6 months without charge to give an adequate crank (3 months interim charge recommended). I can't find anything on the net about a minimum charge being held. My MH is in storage so I can't actually look at the battery. I am sure I do remember seeing this on the battery itself & thinking why was it not on the blurb anywhere. My memory is not the best though so now I am not sure if it actually meant that, so until I can revisit the battery take it with a pinch if saltThe powerframe technology is supposed to be good for batteries in storage though, so would recommend buying a battery with that technology.
The Yuasa is doing well, but the lack of Winter Sun in Fife is playing havoc with keeping starter and leisure battery topped up. We were hoping to have an Ablemail AMT 12-2 Battery Relay [with 2 dedicated Lithium Leisure Battery settings] fitted yesterday but the Installer has been taken ill, so, 25 mile trip once each week to charge up starter battery and warm up the engine, until we can get a revised installation date [New Year at earliest, and that will be dependent upon Omicron spread and restrictions]

Daryl managed to track one down 'locally', think it may have been a cancelled order [2 x Fiat Professional Dealers +2 x Motorhome Dealers had told us that the ECUs had been on Back Order for months and nosign of delivery dates]. Daryl did say that stuff is filtering through, but you wait and see what turns up. Possibly best to phone him.
He is not cheap, but he is very thorough and skilled [and a wee bit grumpy with it when under pressure ...] but he gave us print outs of the before and after electrical tests, and he wouldn't let the M/Home come back to us until he was satisfied that he had traced and corrected the battery drain that was back feeding the Leisure Battery, and that we would not be phoning back 3 days later to say that the problem had returned. We left the full set of Manuals, Elektroblok diagrams, Fridge Manuals etc, and when we collected the M/Home, there were Manuals at every corner of the vehicle, and evidence that the circuits had been traced through painstakingly. PM me if you want more detail, if that's easier than clogging up this Thread

Thank you for that, very interesting!! Probably more comprehensive than my icarsoft , I expect the 'security gateway' will be coming for the Ducato!! Honestly, just a licence for FIAT to print money, having recently looked at the govts right to repair scheme, which from memory is basically limited to things like the door seals on washing machines & a few other appliances, no doubt FIAT have every confidence that the money will be printed forever....

I think you are correct they will all do the security gateway set up very soon on all new vehicles.
I also would guess that after a very short period there will be software / kit to break the gateway. not sure i will own a van young enough to worry about that though.

My fiat has just had a 0100 - fault inside ecu - due to low battery - 11.8v.
None of my software - multiecuscan included - was able to reset it, so I paid £90 to crash data. Back next day so obviously an easy reset.
Annoying that Fiat havn't put in circuitry to prevent this anoying money maker.

My current precaution involves putting the van on EHU for at least 3 hours, the day before I want to take it for a drive. A faff that is FIAT's fault.
Anything approaching 7 days standing idle without charging the starter battery is a risk I prefer not to take given the shortage of replacement airbag ECU modules. Even though the 6 month old starter battery voltage is nominally 12.6v my trust in it holding enough charge after 7 days or longer is at rock bottom.

I have no such option with the van being in storage, at the storage they told me some newer vans discharge after a couple of weeks, because of the high parasitic drain of the electronics.
Obviously a major cost to provide EHU charging as an option rather than just running the engine once a month, but I would certainly pay extra for that service !

If I were in your situation I would get a portable Lithium "generator" like one of these to charge your starter battery at the storage site:

My paranoia extends to using a Multimeter to check the starter battery about every 3 days, especially if the Solar Panel has not produced much feed for the Leisure Battery ['Nil points' for 4 of the last 10 days, and a maximum of 10Wh each day during this period], checking again just before the Solar switches off to see what current has dribbled through to the starter battery; and, before starting the Van, waiting for the 'systems check' lights to go out, checking that the airbag light has been extinguished [thanks to Phill D for that tip!]. Then take a 22-25 miles drive every 5 days or so, say 3 times per fortnight. Today has been the best sun for abut 2 weeks [but still a Sea Mist 100m from the Van!], and the Solar has managed 20Wh at a maximum 5w over 5hrs 15 mins, putting the Leisure Battery, which is still on 'Absorption' at 13.47v. Probably 15 minutes of sunlight left [14:35], so my 'End of Day' starter battery check looms large!

I use a bm2 battery monitor. Allows me to read the starter battery by Bluetooth. Great piece of kit.
Thanks. I assume it will not reset the airbag ecu though? Otherwise Crashdata would not be so busy. I'd happily be corrected otherwise.

Being stop/start, my van runs to more than 14.6v when running.
It is really poor design if an ECU errors at a voltage like that - it is relatively easy to protect against.

No it won't reset the airbag ecu, but it will report, identify and clear all codes, it also allows you adjust and change many values in the system, many of which are best left alone by us mear mortals.
It will realign ( proxy align) new components etc.

PS, it may reset the airbag ecu depending on the error.
I have previously reset my airbag warning light but was unable to repair the ecu fault.

Phill,
Just for reference, my original ECU Fault was U172687 Body Controller & Instrument Panel in the Sensory & Diagnostic Module; and that is a code that means the ECU is gubbed and needs a replacement ...
So that took care of 1/2 of the Xmas present budget, and the reprogamming/proxi alignment, general diagnostics and 3rd new starter battery took care of the rest ... 'Merry Xmas, darling, I bought you a Yuasa starter battery, using your credit card ...'

i had to replace mine in the end after around 3 warning light resets. had some difficulty proxi aligning the new one, even with the correct software package but got there in the end.i bought the Multiecuscan as i was having constant trouble with the other bain of Ducato's the DPF sensors.... i seem to have sorted that out at least for the past 3 years.
simple resets are charged at £70 a go locally so it has paid for itself over.

My bill didn't quite hit 4 figures, but it came quite close, including tracking down the parasitic backfeed from the starter battery to the leisure battery that was using the Electric Step 25amp circuit as a conduit through the Elektroblok EBL99. Burstner wouldn't offer any help with more detailed wiring diagrams so the auto electrician did it one loom at a time and the inside of the M/Home did look like a bomb had gone off, but I didn't want to pay another hour's labour for the internal panels to be put back nicely etc. I can do that low level work and make sure that I put the Manuals etc back where they live ...Ouch!!

Had an appointment to have an AMT 12-2 fitted this week at Wildebus in the Scottish Borders, but David, the proprietor, has been taken ill, so that's curtailed the spending until New Year! David also supplies a Radio Loom for just £15, which kills the power to the multimedia unit, rather than leaving it on in 'doze mode', so we'll have that fitted too, given the very limited Winter daylight/Solar Power generation ... Anything to save the starter battery and ECU from impending disaster!

Crash data in Liverpool have a stock of new Fiat/Peugot airbag ECUs at the moment if anyone is looking for one. I’ve given up on my old unit and bought a new one from them….

£360 for a new unit & proxy alignment from Crashdata, doing it myself, wish I had FIAT dealer locally that cheap!!! Approx €150 & £40 tax & post from the Ebay dealers for a S/H unit programed to your setup.
Our van too has the air bag light illuminated. However, I read on the Out and About Live forum that complaining to Fiat had resulted in a new Air bag ECU FOC and only pay the fitting charge.The vehicle was a 2016 Fiat! So, I have emailed Peugeot Assistance and they have replied this morning to arrange a telephone coversation to-morrow(21st).At this point I have not been able to successfully scan for DTC codes because my scanner cannot connect properly. To this end I raised a support with Autel ( I have an Autel MS300).I had a phone call from their agent this evening from NEW YORK!!! The Autel agent told me my vehicle was too new for it to work (2016 Peugeot Boxer).Hows that for customer service? Impressive I think. He even suggested a scanner that would work an AutelEP200 which uses your phone on bluetooth to communicate.I still have to clear this with er!! my wife! Lets see what happens,I will keep you all posted.
Well,I had a phone call from Peugeot Customer Service from Marocco!! The lady pointed out that a diagnostic scan would be rerquired to pin point the problem.It was also pointed out that I needed a full up to date service history.I've only had the van 10 months but fortunately the service book is stamped up to date.I had to book the 'van in to our nearest Peugeot dealer who fortunately has serviced the vehicle since 2018. However, as I need diagnostic check to find the fault, that will cost £133.02!!

So a FSH may have saved the module in some way ? Anyway Good luck with FIAT, sounds promising.
