rotten egg smell from exhaust
« May 14, 2018, 22:53:30 »
i have a 2016 i30 active x

for months now every so often the car smells like rotten egg gas. my first thought was the cat is on its way out but i heard there may be an update to the ECU to fix the problem.

has anyone else got this problem??
has anyone else heard about any ECU update regarding this problem??

Welcome.  Is it petrol or diesel?  Our 1st i30 (a diesel) used to get a bit on the nose in some situations.  Can't recall this particular issue being mentioned much if at all on here. Hopefully you're right and there is an ecu update.  :Good_luck:

G'Day exadus23,
Have a 09/16 Active X , sometimes there is a smell out of the pipe. Think it's more of a e10 stink.
Varies from none to whoa ! .
Try normal unleaded for a while and compare.
A battery will smell like that if low on water, but, you should be having other trouble by now.

Keep us updated.
