The Griff is parked inside the garage when not in use.

Of late, there is a sulphur/gas like smell coming from where the car is parked.

It has got quite strong now and can be smelt from outside the garage door and in the hall.

I'm sure its coming from the car.

Any suggestions what this could be?

If it's a catted one, then it's the cats. if there's sulphur in the fuel, then the cats oxidise it to SO2, which stinks. You get whiffs of it in the street occasionally.

If it's not a catted one, then gawd knows.

Yep, it will be the cats, try organising some ventilation in your garage...

Yeah, it is catted.

Does this mean they are knackered or what?

How can it be prevented?

Yep - cat pee stinks. Won't ventilation holes just make it easier for the cats to get in though?

This is sometimes just an unpleasant feature of catalytic converters, usually nothing to worry about, the smell usually comes and goes, ignore it, unless it is there all the time, then take specialist advice....

How can it be producing SO2 if the engine's not running?

'Cos the cats will be full of gasses, which will diffuse out over some time, once the engine is switched off.

No, the cats are not knackered - they're doing what they're supposed to. It may help to change brands of fuel - in particular to switch to a low sulphur brand.

I only asked as mine never does it - ah, but then, I just remembered the offending devices fell out in a servicing accident...

I use Optimax which I believe to be really low in sulphur.

Maybe not low enough!

Lazyitus, solve the problem at source with a tin-opener, big stick and some gaffer tape to stick it all back afterwards.

Besides, my car is safer - SO2 dissolves in the lungs to produce sulphurous acid... and think of all the little kiddies that would be affected otherwise...

Suppose I'd better get on with some work!

had this with a chim of mine a few years ago, turned out that the lambda sensors had gone. easy to replace. take car to any garge and ask them to check your exchaust emmisions.

One hundred and fifty.....

Think you'll soon find out at MOT time if there's a problem, but surely if the lambda's are sh@gged you know about it a bit sooner when the ECU throws a wobbly???

If there is a sulphur smell when the car is not in use then I suggest you check out the battery, it is full of sulphuric acid, or at least it should be. Check it has not cracked and is leaking.

And be very careful - if the smell gets stronger in the battery area get some rubber gloves on quick, and don't touch anything else or you'll get holes in it! Can't see how a battery can split, but if it has hopefully any leakage will be retained in the battery box and not got into the carpet...

It would appear I've found the problem so I thought it only courtious to let you know.

As my car has been away from the house for two weeks, I was surprised to find the whiff still lingering.

Would appear we have a gas leak!

Thanks for all your concerns!
