Question 2015 500L MPW Dualogic - No Temperature or S/S

Hello,

I am a new owner of a Fiat 500L MPW 2015 Dualogic Pop-Star (no climate control); I used to have a Stilo back in the day and am returning to the forum (I fitted the cruise control install following guides on here to that car - very useful).

Anyway so the dash has no lights - so all seems fine; however I notice the outside temperature readout is just dashes? (attached) Is that normal or a sign of a broken temperature sensor?

There are two further things that I think could be related but I'm unsure.... the stop start (S/S) doesn't appear to work; press the button says connected, says disconnected but nothing actually happens. Again no lights or warnings to indicate it doesn't work. Could this be because it has no valid outside temperature?

Additionally (and maybe unrelated) the passenger side wing mirror is secure but it doesn't half wobble/vibrate - I suspect someone had it off at some point and its not replaced correctly - but I understand that is where the temperature sensor is? Or am i wrong?

Any thoughts on where to go would be great; thanks

Reis

Re: 2015 500L MPW Dualogic - No Temperature or S/S

Slight follow up, In looking at the passenger side wing mirror it appears the sensor is missing (attached). I've not managed to get it open yet as I'm not sure how.

Does anyone know what sensor is fitted? I imagine it's a thermistor of some description. I'd like to order one or find out where to get one. Or is it a whole wing mirror replacement? (Seems extreme).

Solved...

500L MPW Pop Star doesn't have a temperature sensor! Only the automatic climate control models do as far as I can tell. I took the mirror glass out to check and no cabling is present so I suspect that its true; unsure if you could fit one.... as I understand it the mirror goes to a plug maybe its wired from the plug into the car but not from the plug out to the mirror (if you follow).

Autostart starting working - I'm guessing as it was reset at a dealer, new battery etc it took a while to learn in what was happening. Seems to work on the money now.

So issues resolved [Solved]

I am not too sure about your temperature sensor as I have a 500L MPW Lounge without climate control and it does show the outside air temperature on the uConnect 'More' menu and on the dashboard.

For start and stop, in some conditions, the system won't activate. Mainly in the cold and when the battery is not charged enough - I believe it has to reach over 6mph before the system activates.

If the ECU has been reset, the car will have to learn the neutral signal for S/S.
