That is how I understand it. No one has yet tried the "pedal pumping" trick with a before and after check of oil degradation status with MES or similar so we don't know for sure it it works properly.

Re: Flashing Oil light - how to reset

As luck would have it the cable I use to interface with my Triumph motorcycle is the same one for connecting with a Multipla.

I downloaded MultiEcuSacn and can confirm the oil regeneration was reset, so the pedal pumping which turned the light off does work. See below screenshot.

I have a Fiat 500 diesel 1.3 Multijet and although I had the car serviced and engine oil and filter changed I had the flashing oil light appear and the message in the dash said change engine oil. I took it to my usual mechanic as it was serviced where I purchased the car and he confirmed the oil had been changed as had the filter but I couldn’t get the pesky light to disappear! Just tried the instructions in this thread and it worked. The light has disappeared. So thank you very much!

Re: Flashing Oil light - how to reset

Welcome to Fiat Forum. As you hve found Multijet diesels with a DPF have an additional reset that normally fiat specific software that your mechanic did not have. It appears there is another reset method that appears to work.

The second is the oil degradation counter in the engine ECU. There is no light to tell you to reset this but if it is not done (even Fiat garages have been known to miss it) eventually the flashing oil light will come on and the DPF will stop being regenerated. If this is ignored you eventually get limp mode and a blocked DPF. Only Fiat specific software can reset the degradation counter. It' related to fuel getting into the oil during DPF regeneration.
shaggy1970's post is a little misleading as it says "that's all" without mentioning diesels or DPFs.



Robert G8RPI.
I drove a peugeot bipper with a fiat 1.3 multijet diesel engine for 6 months with the oil light flashing, and it kept on doing regens and never went into limp mode. I reset it with autocom in the end and serviced the car again after that.
On a side note I tried this pedal pressing malarkey on my 2014 doblo 1.6 multijet which is whinging about my service coupon has expired, but it didn't work. I've ordered a set of leads and downloaded MultiEcuScan anyway as I recon it will be helpful for various things in the future.

Re: Flashing Oil light - how to reset

Interesting update. Although my oil light wasn't flashing I tried this procedure again and when I restarted the car, the oil light flashed 3 times and went out. I think this might have indicated that the counter has been reset. (don't worry, I am servicing the car this week). However the pesky service coupon expired message is still being announced, and it still says 0 miles left on the service section of the display.

Re: Flashing Oil light - how to reset

I own a 500L 1.3 diesel and I also went to National to get an oil change but they couldn't reset the light. I followed shaggy1970's instructions and when I turned the ignition on the light flashed a few times and then went off. I don't know if the oil degradation status is reset so I'm going to a Fiat specialist garage on Tuesday to find out. I called the local Fiat dealership in Poole and they were asking for £99+VAT to run diagnostics I will post an update after my visit on Tuesday

My understanding is that you need to plug.in to correct the degradation index
And the service coupon message.

My mj isnt DPF.. so its not something I have needed to cover.

Resetting the oil degradation status is a necessary part of the job of carrying out an oil change on a DPF-equipped car and failing to do so could lead to some expensive problems later. If I had taken such a vehicle for an oil & filter change and this was not done, I'd refuse to pay.

Re: Flashing Oil light - how to reset

My 08 1.3mjet 500 is going in for a new sump and oil change on the 14th. I have multi ecu scan. I'll take a screenshot before and after the work to see if the mechanic reset the counter. I'll try the pedal pumping and take another screenshot afterwards.

We are taking ours for an oil and filter change as the flashing oil light is on. We buy the parts and a local guy does the change for £10, and he says he will get the counter reset

I'll report back how it goes and if he had any problems resetting .
