Oil Change Warning Light on Doblo 2006

Doblo 1.3 Multijet Query
Hi all, as you can tell i am new to using forums. Due to the fact that my local Fiat dealer is extremely unhelpful it was suggested that someone on the forum may have had the same problem. After 3 oil changes between 5K and 12K on my Doblo I am getting sick of the warning light coming on for no real reason, other than that of profit for my Fiat dealer. They charged me 32.00 approx to turn it off the first time and they still want the same to do it again, i have been using the garage that i bought the car from to do any services or oil changes as they are cheaper than fiats.
Basicly is there any work around to stop this warning light on the dash other than paying a Fiat dealer?
The vehicle in question is a Doblo 1.3 Turbo Multijet on an '06 Reg.
I have been advised by the local Trading Standards Office, to send a recorded delivery letter to local Trading Standards Office and the OFT declaring it to be a Restrictive Trade Practice.
This may not help me directly but it might get some cogs turning in the system, Fiat have told me that Citroen and Jaguar do the same stunt.
Apologies for being long winded but just wanted to get my point across.

There is a software update available for the problem you describe. This is not a con by Fiat trying to get you to have more oil changes, it actually extends most peoples engine oil change service intervals.

Somewhat bemused over the need for such frequent oil changes - does anyone tell you why (or have I read it wrongly)

and secondly why can't the supplying garage deal with the issue - presumably they are paid for the work by you and yet they only seem to do half a job - (or have I read it wrongly)

thanks

Re: Oil Change Warning Light on Doblo 2006

most cars have been running well for over 80 years without the need for oil sensors., which i'm sure if research was done does not take the average motorists service mileage above the standard average hence saving money but rather shortens and increases oil change frequency.

Common sense needs to prevail here if you are putting in a fully synthetic 5w 40 diesel formulated oil in your engine it will more than do 12000 miles before a change possibly 18000 check to see what oil they have been using as if poor quality semi synth might be causing the problem. either way get it fixed by fiat for good or even ask them to disconnect the sensor wire and go back to standard 12 month or 12000 mile schedule that way we all know where we stand.

I'm made up with my 1.9 8v multijet because it is a simpler engine no DPF and no oil sensor and NO problems!!! Love modern diesels but have to say there getting a bit over engineered these days.

They have to be 'over-engineered' though to meet emission laws & the demand for performance (and economy) by the public...certainly better than tractors engines in older diesels.

Ok Chrisb, a few facts, there is no sensor, the oil degradation is worked out using information obtained through its engine management sensors, not an oil sensor. Secondly when a vehicle with dpf comes into a dealer the technician carries out an oil degradation inspection using examiner, this gives the approximate mileage (assuming similar type, and style of driving of previous mileage) before an oil change is required, typically we have found oil degradation measurements to be extending to 22000 to 25000 miles. This information is given to the customer or used to make a decision whether to change the oil or not. Many customers are unwilling to let the oil change be extended and prefer a yearly oil change. When the oil is changed the degradation data is reset using examiner, the quality of the oil is unknown by the management system, and is not used in the calculation.

Stand corrected

Interesting that most want a 12 month change irresepective of the data, beggers the question why bother having the technolgy. I'm afraid I too would want the oil change at 12 months as have a renault laguna 2.2dci which has 18 month 18000 mile service schedule which is woefully inadequate.

Better Yes!!! but at what costs to the publics pocket!!!!!!!!

making the point T that it has reached a point where maybe due to the emissions, economy, performance etc of diesels and the cost of derv at the pump that they have started to lose there advantage if the high engineering causes very expensive repairs early on in a life of a diesel vehicle.

have to say how ever much I love my Doblo the new ones just seem to have so many extra things on them to go wrong( and they do) that maybe petrol cars in the long run with a far simpler design aren't so bad after all!!!!!!!!

I wasn't asking you directly i was making a general statement nor was i having a bash at fiat, its a general observation in motoring.

....just giving the facts. Techs get a slagging (possibly more so) just as much as anyone else.

IMO I think the goverments of this world should come down harder on industries polluting the air/sea/earth rather than the motorist by ever stricter emission laws. DPF equipped cars should be road tax free!

You may get hacked off with it Chrisb, but so do technical people when non technical people make statements or give opinions which are not based on fact but on heresay. At the end of the day everyones opinion is important, as our customers are not technical (on the whole) and what seems perfectly logical for techs may seem totally ridiculous to our customers, and if we dont explain or listen then how can we learn how to make things more customer friendly?

Well said that man and thank you for the enlightement!

Please take the time to explain more on this subject as and when you are able - I am not technical but would like to understand whether DPF's are in fact going to last the course.

Re: Oil Change Warning Light on Doblo 2006

Hi,
I`m a newbie to the forum but thought I`d share a bit of good news about this "Change Engine Oil" warning light. Basically this is a service warning which won`t go away even after you change the oil yourself. Fiat want to make money for nothing by insisting that they graciously turn it off for you! Not one to give up too easily I perused the web and found our American distant relatives driving those huge monster machines (Chevrolet site NOT FIAT!!!) had the same problem and this is how they solved it (to give credit to where it`s due!)....

"To get the "change oil" light to turn off, you turn the ignition to the on position (the position right before you start the engine), and mash the gas pedal three times. The engine should not be running during the process. The next time you start your SUV, the "change oil" light will come on with the rest of the dummie lights and go off with them as well. This is the process that 1 useon my 2003 trailblazer and have also read that it works on 2002 and 2004 and can only assume that GM most likely kept it for the rest of the year models. Hope this helps everyone out"

Well it worked a treat on my 1.3 JTD 05 Doblo THANKS GUYS!! Seems that when they`re not dropping bombs on people they can be quite nice and helpful!

Ps. you may have to try this a few times before it works, the main trick is to push the accelerator (gas) pedal down hard into the carpet! GOOD LUCK!
