Advice on reading fault codes

[Wayne370Z]

Anyone offer any advice on the following. It`s for the wifes Mokka 1.7D but I presume it`s the same sort of thing with most cars and I think there`s far more competent and technically minded people of here than the Mokka forum.

Every now and again it will display a "Service soon" message on the display. It isn`t due a service till July and I first thought they had just not reset the mileage/service interval after the last one as it had just about reached 20K.

However, have also read that it can throw up this message for minor issues and so bought a code reader and downloaded a couple of free apps to try before taking it back to the dealers.

I have this morning tried it but they both just show no fault codes, no pending fault codes and no permanent fault codes. Am I right in presuming that this means no faults currently and no previously stored ones and, if so, why is the fault not there.

Is it perhaps down to the apps and the paid for ones will be better at bringing up any faults ?

Cheers, Wayne.

i'd guess the apps,

 

do you get a confirmed connection with the ecu?

 

if its not due a service, Could be something simple like an emissions sensor been triggered etc.

Yeah it does connect to the ECU (eventually after a bit of messing around) then checks it and comes up with the - 0 Faults.

service light coming on is not a fault so that`s why it displays no fault codes
