Hi Guys,

I've managed to fix most of the faults on this car which were caused mainly by water ingress after an accident in the front ( I purchased as a non runner from a salvage yard). I have changed all the can bus connectors in the gutters but there is this one fault that is puzzling me.

A couple of things, firstly the fault is indicated as a "i" instead of "f" in the engine ecu, so does that mean its for information only and won't affect the driving? Secondly since I think I have fixed everything that needed repairing or changing and that the signals are "plausible" is it a software/programming issue?

I have noticed that the DPF has been removed, is this possibly something related with that along with the engine ecu not reprogrammed correctly to delete the dpf? does the coding need to be changed in IC to reflect that?

There are no fault codes in the IC.

I have also been told that it might be when someone has changed the mileage? I can't see any signs of that though.

Any ideas greatly appreciated as I'm clueless now and shooting in the dark.

In my experience that sort of message is often due to a can blocker device fitted behind the instrument cluster to reduce the mileage being recorded. Might be worth pulling the cluster out to check. It's pretty obvious if it's there.

Oh right I see, but isn't it taken off when you get rid of the car ? Does that mean the mileage wont go up on the dash when driving?

They are switch on and off via a combination of steering wheel button presses iirc

Or they alter mileage that is sent from the engine ecu to the cluster. They are programmed with whatever mileage the nefarious installer chooses. As such, they are left in permanently.
