interesting
I have a problem with the three warning lights.
They come one when ever they feel like it.
After being parked for a while, when I start it up they are not on then after 5 / 20km they will come on
All this started when I changed the seal on the fuel pump RR 2005 4.4 petrol
Any spelling mistakes are the fault of spellchecker

Present MERC 180e, RANGE ROVER L322, JAGUAR XJS, MERC 280SE, MG F, JAGUAR S-Type 6v 2003, jaguar s-type 8v 2004, Ford Cougar

Yes mine used to pop up the regular three codes - now gone three days since - at a similar place as you mention... around 5 - 10 - 20kms... and I wonder why at this point?!? I used to think it was when the vehicle - more the engine - had reached full working temp?!? Are there any other thoughts on this alert/ping poppage timing/distance?!? Just wondered...
