Title: Engine/exhaust egg like smell
Post by: Wakkk on March 01, 2020, 12:19:12 am

I’ve noticed when revving and giving it some on quiet roads that the car gives off a kind of rotten egg smell, any idea what it could be? Mk5 gti in question

Is this since you having a misfire?

Could be because unburnt fuel from the misfire has got into the cat and it's burning off.
