November last year I had the " engine system fault " message appear on the dash and the little red led to the right come on my focus 1.6 tdci zetec.. After going to my local Ford dealer I was told likely cause was that the additive eloye needed topping up.. had this done at a good local garage as it was cheaper than the main dealer.. this solved the warning on the dash and has been fine for last 6 months...

on sunday the " engine system fault" message reappeared... been back to the garage where had the additive topped up and they put it on the diagnosis which came up with 2 codes of " p2485 & p2585" the garage are now saying that they think the actual dpf needs replacing!!!

any help or info to clarify this would be grately appreciated... car has done 78k

cheers..

hi mate,

the light can sometimes show if the regeneration process has been interupted or not completly processed.

best advise i can give you is get the car up to temperature then take it a run for 15minutes on the motorway and keep it in 4th gear.

this will keep the revs high and allow the DPF to get hot enough to ignite the suit.

if this doesnt make any difference or stop the light from coming on in the dash then the garage are correct.

and if you want a second opinion on what ive just advised you.

ive read it on the AA website.

cheers for the reply lenny.... Just been out for a good 40 min motorway blast at high revs.... engine system fault message still there.. just wondering if that would naturally clear itself even after a good blast or would it still need restetting/clearing at a garage and see if it comes back...

thanks..

it should reset it self from my understanding mate,

and the fluid has been topped up by a garage so i dont see any problems except for the light.

the aa guide i linked you to says that if the dpf is blocked you will notice a lack in performance and you havent noted any so i persume your performance is ok.

one last thing i would try is to get the garage to clean your pressiure sensors on both sides of the dpf then see if the light stays on or off. other than that i suppose we can only believe what the garage say mate,

unless anyone else can advise

Could need whats called a static regeneration or you could have sensor issues ie dodgy sensors or pipes leading to them. As far as I know only your local Ford dealer can do this. If its not this youll be in the best place to have it correctly diagnosed.
