Technical Wing mirror advice

[Steve24]

I’m looking for a new Drivers side wing mirror for my 2015 Fiat Ducato campervan.
My original mirror is manual, not heated though does have a temperature sensor.
I can only find on line a manual mirror without the temperature sensor.
The only mirrors with the temperature sensor are electric.
Would an electric one be ok though just not work with the electric functions?
Also the option of 5w or 15w indicator bulbs is offered and I’m unsure what to get.
Grateful for any advice

I think that you would have difficulty in adjusting the mirror.

They do seem to be rare, but available if you're prepared to wait a week or so (If I'm reading this correctly).

You need the indicator bulb wattage to be compatible with your van, otherwise it will throw Canbus errors. I think most are fitted with 16W bulbs now, but earlier that was a fitment largely on chassis destined for professional motorhome conversion, so yours might well be 5W.

Not definitive, but I think the 5W version was fitted with an amber bulb in a completely clear reflector, whereas the 16W had an amber surround in the reflector as well.

Whatever, you can check by looking at the wattage on the original mirror (or check the other side if it's completely destroyed or missing). It's relatively easy to get the alternative bulb and/or reflector to fit the replacement mirror. (widely available and and not generally difficult to fit).

Thanks Hugh. That link is what I’m looking for. Yes it is 16w. I’ve previously replaced the passenger side with a mirror that came with a 5w bulb. I was unaware when I ordered it though managed to change the bulb to a 16w one and sorted it. I can get a manual mirror without the temperature sensor for about £50 so will need to think if the extra £70 is worth the cost.

You need that temperature sensor because the computer uses the temperature reading from that to adjust the engine, and will give you all sorts of problems if its not connected. Can you get the sensor from the old mirror? - preferably fitted in the new mirror for accurate reading and ice warning but doesn't have to be for engine adjustment - you could stick it inside the door - just as long as its connected.
Amazing how many different mirrors there are for the Ducato. A passing council lorry smashed mine when I was parked - their insurance paid and sent someone to my home to fit a new one - I had to send them photos because they said there were something like 64 different mirrors fitted to the Citroen Relay (Ducato X2/50 with a Citroen badge)

I may be wrong, but ISTR that the 15W bulb is only fitted on the LWB heavy chassis (Maxi) vans that have the side marker lamps also, and all others use the 5W bulb. The other thing to bear in mind is that some vans use clear bulbs with an amber plastic lens inside the lamp housing, but others use an amber bulb and a clear lens. But if your original indicator lamp is OK you could just swap that into the new mirror.

 

[Steve24]

Went for the cheap 5w mirror without the temperature sensor. Went to Halfords and bought a 16w orange indicator bulb though as it is slightly bigger than the 5w bulb that it came with it won’t fit through the hole in the lamp housing. Very frustrating as the wing mirror I previously bought for the other side has enough room for the slightly larger bulb.

Reg65 I dont think the Ducato uses the mirror sensor for engine purposes. If you have any evidence contrary to my opinion then please publish so I can review my view.
Heres my responce to a previous thread about mirror temp sensors
The boxer and relay use the ambient sensor for regen with engines that use ad blu. The ducato does not, it uses a different temp sensor
There are a number of ambient temperature sensors on the Ducato
1 IAT in the MAF sensor
2 with MAP sensor (not exactly ambient but is use to check MAF )
both controlled by engine ecu
3 temp sensor in mirror
controlled by body ecu.
with the Adblue models there are even more temperature sensors( on the fiat they are in a separate Adblu module.)
The temp sensor in mirror has a significance in regeneration of adblu models definitely Peugeot Citroen models. Was this then inherited by the adblu fiats just using the pre existing adblu methodology?
Does it have significance in regeneration of X250 or earlier ? No it was an optional extra on the X250 (maybe x290) many with and without but have the DPF.
I suspect the IAT is used for the regen function, why? Because these are all important critical to the engine and are controlled by the engine ecu on the high speed can bus. The mirror sensor is controlled by the Body ECU on the lo speed canbus and is used by electronic climate control and the comformatic.
The information in the X290 Converters Manual implies that (at least for non Ad-Blu models, which it pre-dates) the external temperature sensor is a requirement only when the vehicle is fitted with Automatic Climate Control and/or the Comfortmatic gearbox. Some vehicles are provided as Chassis Cowls, without any mirrors (or doors ) and thus the converter must add a sensor elsewhere. Hence the questions wheres my Hymer A class temp sensor.
Thus the mirror sensor does have a significance but not to the extent of the Doom and Gloom merchants i've read elsewhere (i repeat elsewhere)

Is the Fiat adblu system no longer used in the latest Peugeot 2.2 engine thus the mirror sensor may be relevant to 2024 models.

My Motor home is Right hand drive and has long arms. Thanks to a Black Van man in the Yorkshire dales Ive had the oportunity to see if a medium arm mirror would fit. Having read about other Rapido owners doing the same with sucess, ie the long arm sticks out too much., i decided medium arm was...

Its just that i saw a you tube video of a Ducato/Relay/Boxer driver who had all sorts of trouble with engine management which he traced to replacing his broken wing mirror for an aftermarket one without the sensor
Unfortunately I didn't bookmark it - Just done a quick search of you tube and didn't find it but found this one

That's a Peugeot Boxer though. I was sceptical of that video when I first saw it. Whether or not the ambient temperature sensor does affect regenerations on the Boxer I have no idea. It may be correct, but I always approach YT and social media videos with a large dose of scepticism. Truth soemtimes takes a back seat to revenue for the creator

I agree with @theoneandonly though. The functional description of the DPF systems on the X290 states that regeneration activation is based only on the values obtained from the pre and post catalyst exhaust gas temperature sensors and the differential pressure sensor. Regeneration starts when the catalyst inlet gas temperature exceeds 230C and temperature in the filter exceeds 600C with free oxygen in the exhaust gases or greater than 8%. There is no mention of the ambient temperature sensor at all.

Unfortunately another utube myth turned into legend if not truth , a Boxer/ Relay is not a Ducato even though a bit lump is the same another big lump is different. I quoted readily available fiat info. As yet i have not seen Peugeot doccumentation refered to wrt mirror sensor
