Technical Service reset MES

[The Panda Nut]

I checked Peanut today and found the service reset had not been done yesterday. I hate resetting these things!! Firstly it prompts you to fill in day month year for the service, but in fact refuses to accept the reset until you give it month day year, Checking the miles to next service in the cars menu I find its showing 9500 miles??? The nearest to 12000 miles I could get it was to reset the interval to 20000km whereapon it says 12500 miles in the cars computer menu. Next I find the service coiupon figure was 1. As this was the cars 3rd reprogramming it should have been 6. So I reset the coupons accordingly. Now thinking about it there are more services in the book than 4 so I need to do this again. What a pain. It makes you wonder who has been fiddling and getting this wrong.

You can disable this carry-on altogether using MES. Which is what I did.

I'd be interested to know how to reset and reactivate the interval, though. It has deactivated itself since the first official service was done in 2013, giving up on my case after reminding me for about 1000 km.

Using AlfaOBD on my Punto, I found the interval is still set to 15 000 km, there is also a time option which I didn't explore and I remember there is a "service coupon" item but since I didn't know what that meant I didn't try it out. So I imagine one would select "service coupon" and then what?

Thing is, doing the oil change way to late (beyond 20 000 km) because I forgot about it has happened before.

I use MES and connect to the service module and the adjustments tab Under this are
last service date
Service interval
Set number of coupons
Next service km reset

Last service is the one you have just done but enter Mo/Day/Year not day month year as initially suggested.
Service interval should be 12000 miles. I think I set this at 20,000km. For us the car computer is set for miles and converts this to miles. It seems to revert to 9500 for reasons I dont understand. At 20K km is now showing something like 12049 miles which is near enough for me to accept it. The value you set is the one you should see in teh computer menu when you select service. It will count down to zero and should start to prompt you about
Service coupons are for ? but keep a record of the number of service resets. This must be >0 for the reminder system to work. Factory set at 09 and neeso needs resetting when it reaches 1
Next service km reset You reset this and the ECU remembers and starts the countdown. My 2019 car has days to service as well.

Note
If you disconnect the battery at any time the service counter settings may get lost. Coupons stays but the interval seems to be lost or upset, and the countdown is lost,

I hope this helps

Thanks! The advantage with MES seems to be: you don't have to worry about the modules.

I read on an Alfa forum that the service reset for an oil change using AlfaOBD needs actually three things:

• tell the engine ECU that an oil change was done
• tell the body computer to reset the service interval
• verify that the service coupon counter has not reached "zero" as it will apparently stop reminding once it reaches that number (counting down from 9)

I have to try and check this out for myself, as there is also some conflicting information on the net. Some information seems to be stored in the instruments module, too.

And changing the service interval distance apparently restarts the counter.

‘Service coupon’ is Fiats way of recording that a service was done - think of it as a stamp in the book (in the US, cars - of any make - come with a book of coupons for each service interval and one is torn out at each service)

Regarding the distance between services, Fiat reduced the recommended distance (for the TA) from 18,000 to 9,000 at some point (more accurately a round number of km) and that’s prob why it defaults to 9500 (as being the nearest round number in miles to the revised distance in km). At the same time the interval (in months) was halved.

With a diesel Panda, there’s another reset to do, to say the oil was changed. The ‘oil change due’ light has no set value for miles, but instead counts DPF regens, so the number of oil changes can be different to the number of services carried out.

 

[Herts Hillhopper]

Also, ‘service due’ message will clear itself 1,000 km after the ‘due’ mileage has passed (even if not serviced — the message clears but not the need for a service)

The service interval for the TA is either 9,000 miles since the previous service, or 12 months - whichever occurs first. So, with low mileage cars it will also stop showing the ‘service due’ (I think) 30 days after the due time.

I was told that with a diesel - if you drive more than 500 miles with the ‘oil change needed now’ light on (flashing red oil can and ‘oil change due’ on the digital display) the car will go into limp mode to protect the engine. Never waited that long to find out (Also flashes up if 24,000 miles or 2 years since last oil change if the DPF count doesn’t trigger it first — which can happen where used mostly for long, fast runs). Since leaving work, my annual mileage dropped from around 16,000 to nearer 8,000 - and the Hillhopper is now serviced, with an oil change, every 12 months regardless (at MoT time). Now I also have the Landy, that will drop further…

I bought the mes software and did all the oil and service resets and dates on my last service it was good to see when my car had its last oil service I even reset it so the car will remind me 200 miles before it needs it's next oil service
