[s-cars] Re: bad cats

[William Noland]

Audi issued a TSB re stinky cats on the UrS. Recommended trying different brands
of gasoline. I've noticed some are worse than others, but it's a matter of degree
of stinkiness. If you suffer from stinky cat syndrome, you might try shopping
around for gas and see if there's any improvement.
