    Question Exhaust smells of sulphur/rotten eggs

    Hi gents,


    Ok, this is a weird one: I've noticed a smell of sulphur/rotten eggs when parking the Rangie - have any of you ever experienced this on a petrol car?


    I noticed it last week, but thought it was a drain/gutter as it had rained the night before. But yesterday when I parked the car, my wife was waiting in the garage to get stuff out of the car, and she also mentioned that something smells funny.


    Since the lockdown started, I only go out once a week for essential groceries, so the car is not being driven much. The shop is 2 km away, so I try to take the longest route possible to give everything a bit of a workout.


    Anything I should be concerned about?


    Thanks

    Also check your battery voltage, could be the alternator overcharging or fault with battery.

    Thanks Jelo, other RRS owners say the same.

    Our Spar is 1km away, hard to get the car to operating temps, even if I take the 'long' way to go shopping.

    Do not be alarmed when you see excessive white smoke bellowing out at some stage. It happens when the cat gets partially blocked, which is not a good thing though. You might even get engine performance restriction. Cats do not like short distances. Best is to get a good burn on the highway.
    I am sure your Spar does not always have the goods you are looking for, which the Spar at Somerset West will have...

    That RR is a petrol. Petrol cats don't get blocked, at least not within a few weeks.
    Algea form in diesel, petroleum and Kerosine type fuels, not in petrol.

    That smell is caused by some hydrogen sulfide, which the cat at proper operating temperature would usually convert into something without odor.
    Since the cat can't get to proper temps, the exhaust smells like rotten eggs. It probably is in solution in some condensation water inside the exhaust system, too. Hence the smell might linger around, even if the car has been switched off for a while.

    Mine does it too, it's the Cat one up to temp or disappears. Takes quite a while to get a Cat to proper working temp. Nothing to worry about.

    Sealed batteries give off a rotten egg smell when they pop (sulphuric acid)

    With spar only 1000m away, why not walk there and get the essentials you need in a backpack? Unless indeed the body isn't willing.
    It's an opportune time to walk the streets as I personally belive crime has dropped during this time. Still be cautious ie don't walk with phone in hand or on ear.

    2 more weeks and you can give the cat a proper burn!

    That was my first thought, but that smell would normally take longer to develop than a short 1km run. I won't hurt to check the battery and charge voltage though
