I have a Mocca SE Turbo 1400cc petrol automatic with a engine warning light on, after diagnostics from the garage I was told to use super unleaded, after filling up the warning light came on again has anybody else had this problem.

You need to find another garage!

Engine warning lights set codes which can be read by the diagnostics - there isn't one for "use higher octane fuel"

A Mokka 1.4 will be perfectly OK on ordinary unleaded 95 RON, just like virtually every other car sold. Your garage clearly don't have a clue what is wrong.

, after diagnostics from the garage

Is this the garage who sold you the car- I think you have bought someone else's problem. As it is recently purchased you have rights :-

If you think THAT is an example of bad medical advice, you clearly havn't had any.

Speculation, because we dont know what the fault code was, (and they seem to be pretty Delphic anyway. ), but I'd guess knock sensor activation is recorded, which would be a fairly rational (though rather treat-the-symptomish) explanation for this advice
