I have just changed the oil and filter with the correct products on my 500L MPW.
I have tried to cancel the flashing oil light and message telling me to change the oil by using the system I've seen on line about pressing the throttle 3 times within 10 seconds etc but it's not cancelling the light. Has this happened to anyone and how did you get round it other than a visit to the dealer.
 
I had a faulty elm327 and couldn't perform the oil reset (the elm interface would flash lights but multiecuscan wouldn't connect to the ecu) and ended up taking it to Fiat.

This time around I will be personally doing it as there is no more warranty left. Manual states (for 2015), diesel engines use 5W30 Acenta C2 Engine Oil (preferably with the Fiat 9.55535-S1 certification for optimal engine performance).

I can't find any of the Selenia stuff around here and importing it is costly (and I can't be sure that its genuine oil from ebay). Castrol seems to have a C2 engine oil with the S1 certification with a much cheaper price; will be using that next time round with a MANN filter (Eurocarparts do deals regularly for weekends).

I believe it should work with the pedal combination as seen in the video?


If the video is correct, the service intervals cannot be reset through the pedal combination but the engine light should? Or is this variant with the P parking gear different to our dual-logics which only have a neutral.

i have the same car, its easy.
turn key on but not eng. hold the small right hand wheel on the steering wheel down, and the same time press the accelerator 3 times. turn off, wait 1 min, then start.the oil will be reset.
 
Not too sure if this is the best solution with the Diesels.

I reset the service indicator and performed the oil change via the diagnostic multiecuscan software so that the degradation counters are reset.

If the counters are not reset by the technique of pushing throttle three times, then the counter will think the oil has not been changed and will prevent further DPF regens (I don't know as I haven't had to do an forced DPF regen, but seems probable that it may not be reset)

What do you mean? In diesels you need both the diag tool and the pedal procedure?

Fiats diesel engines fitted with DPFs normally need two separate reset procedures carried out when the oil is changed. One is the normal "service light" reset that is performed in the body computer (some models have a switch twiddle process for this but Multiecuscan is better). The second is an "oil degradation counter" reset that is performed on the engine ECU. Only Fiat specific diagnostic equipment or software can do this. I recommend Multiecuscan. Note you may need an adaptor lead and the very cheap <€15 ELM327 interfaces have a design issue that can prevent them connecting to the Engine ECU. This reset is often missed by garages and can result in damage to the DPF or the car going into limp mode.

Thank you, Robert. I am interested in doing the oil changes myself, as I like to buy the best Fiat approved oil myself. God knows what some garages may use.

So, what would I need to buy so I can do both resets on my 1.3 diesel 500L? Can you tell me exactly what to buy and what to read to know how to do it?

Cheers!
 
Hi,
You need a laptop computer running Windows (any version from XP to 10), a ELM 327 interface "modified for Multicuscan" a "yellow" A3 adaptor lead and a registered copy of Multiecuscan www.multiecuscan.net (don't pay the registration fee until you have mangead to get it all working and can read CAN information.).
Asuitable interface is
https://www.ebay.co.uk/itm/Fiat-Alf...-OBD2-interface-for-Multiecuscan/281166266540

and suitable adaptor lead is https://www.ebay.co.uk/itm/Alfa-Fia...r-3-CAN-MultiECUScan-FiatECUScan/153031085002


It can be easier to buy a set like
https://www.ebay.co.uk/itm/NEW-Fiat...dapters-Diagnostics-Multiecuscan/282526378637 .

I've used these sellers but they don't ship outside the UK so you will have to search your local ebay and Amazon for similar items.
You can download MES and play with it without having the interface. Just click the simulate button instead of connect.

Yep, that sounds correct.

I've got the ELM327 v1.4 and removed one of the fuses myself on the cheap. The yellow adapter I got as well imported from China. Came out six quid for the elm and another four for the adapter leads.

When I did my oil change, I didn't even jack the car, I used an oil extractor pump (bought cheaply on eBay) through the dipstick, which is what many garages are doing nowadays.

For the filter housing, I went to a large B&Q last year and bought every single socket of large sizes until I found one which fit and placed it on my socket set. Returned the rest within 10 mins of testing outside the store.

I see! And is this something easy to do? Are there technical manuals available?

Cheers!

Are you using a manual or electric oil extractor? Can you get it all out using this method?

The software has on-screen instructions and there is on line manual. Download it (free) and have a look. If you use the "simulate" button rather than the "connect" button you try it out without an interface or car.

Yep, it got all of it out. I checked the cylinder and it was definitely 3.2L, it did take roughly 35 minutes as I used the small diameter hose, but definitely use the medium hose with the oil extractor to speed it up. I could see how an electric one may suck it faster but I wasn't in a rush and it's definitely cheaper ;)

I used a manual one, put it next to the car and inserted the hose into the dipstick until I could feel it's all the way in, make sure that the tube is straightened.

It looks like this, mine was a generic model from eBay, they should all do the same job to be fair:

Pump a couple of times and this creates some form of vacuum allowing the negative air pressure to be sucked into the cylinder itself.

When there isn't much oil movement and the tube sounds to make the sucking sound, it should be done. On my model, each barrel line is a liter. And 3 and a half was definitely in there.
A stock picture visualizes this:

I tried to jack up the car and do it the old way but couldn't find a sump plug in my parts and I guess I could use the pump to do the oil changes for wife's car and mine in the future.

ELM327 Modifications.

I just modified an Elm327 and just wanted to update this post on the information on how to.

So if you want to modify your Elm327 to support some engine ecu modules of the MultiEcuScan software, you should use preferably an Elm 1.4 and not 1.5 or 2.1, those chips just have the contents on the Elm software on and won't perform correctly. Some board designs do not have a resistor to modify! :mad:

I'll link a reliable Elm327 module to modify here. Do check reviews on others to see if other customers have tried to modify it. Also, you'll probably need to wait two to three weeks for this as it's shipped overseas.

You'll also need the Yellow adapter, check out ebay,amazon or aliexpress for one.

Then you'll need to remove the Elm sticker (use something flat like a flat screwdriver) and unscrew the four screws. If it is an Elm 1.4 board, then it should look like this:

You should see the resistor 121 (in my case) or 1200 between pins 14 and 6

If you can desolder that then do so, if you do not have the tools, I just used a sharp knife to cut the resistor but be careful to not cut other electrical components.

If you wish to put some electrical tape, I have loads and can't find a better use but you don't have to, you can put some :D

Thanks to my Brother printer not consuming loads of ink and loads of UPS blank shipping labels, you can slap on a Fiat sticker on Word and call it a day ;)

You'll also need the yellow adapter if you wish to connect to the service ecu to reset that. Mine one hasn't been very reliable so I won't suggest one but you know there's sites like eBay and Aliexpress.

Now let's see the ebay sellers upselling this go bust :D

Thank you, Robert! It seems pretty easy to get it working!

Cheers!
 
Do I need the registered version? The free one doesn't allow you to reset the dpf/oil lights?

Cheers!

Hi,
Yes, you need to pay the registration fee. Only CANBUS info is supported by the unregistered "free" version on the 500L. You can use this to make sure it is all working before registering.
€50 is a bargain, many garages charge 2 - 3 times that for a single diagnostic read.

Hey, Robert!

Don't get me wrong, I think it's money well spent. Where I'm from I believe they charge about €50 for an oil reset, so just one oil change and it's paid for.

My technical knowledge about these car diag systems is very poor, that's why I need so much help.
