Ok, so the IDS system, the little laptop that plugs into your car and does all the diags and updates, gets update discs set out by ford to update the IDS sytem and any updates for cars that use the system, the IDS is also updated in between times via internet updates, so the only way a dealer can update anything on your car is via the IDS and the updates that ford send or push to it... so yeah the update does exist, it's obviously been released by ford au as it was out in march in the EU and took till like Sept/Oct to be released into the system here, it took about 30mins for the update to be applied to my car. Does it exisit for TDCi and Zetec... well, the first question would be is instant fuel consumption availble on the current models of those varients? From reading the UK forum, from what i remember, yeah it was available for cars with the HMI and those without... anyways, never any harm in asking, it will be interesting to see if anyone else has any luck...
Realistically, the ford dealer isn't going to update anything at a normal service, unless there is a
TSB regarding an required update, if it aint broke, dont mess with it
but if you ask, they should comply with your request, if they can find it and / or do it, then yay!!!
Thats all...
