Hi i30 owners,
I am looking for some ideas on what I think are an odd set of symptoms.
I had a leak in aircon system for a while, but hadn't bothered in getting it diagnosed until recently and so I just never used the aircon. Gas with fluorescent dye was used to detect the leak, but it turned out the leak was much slower than I thought so I had cold air for a few weeks. As the aircon became less efficient, I noticed that after driving with AC on for 15 mins I saw the fuel filter light on the dashboard (never came on before). As soon as I turned off the AC the light would disappear. This happened on 3 separate occasions. I think this seems odd that the two systems could be connected?
Also, this may be unrelated but as the aircon has slowly lost it's ability to cool air (due to leak), I have had cool air coming out the vent at the driver's side and warmer air coming through the other vents.
I am due to take this back to the mechanic to look for the leak in the aircon but I was just curious if anyone has any ideas about why running the AC could trigger the fuel filter fault light?
Thanks for reading,
Fran
