318iS Owners - Cat or Not ??

[E30-Andy]

Do all 318iS cars have a catalytic converter?

Mine has no Lambda probe .... does this mean I have no cat?

ETK implies that all iS have a cat.

[Dom]

thought it was an option?

[Geeman]

Mine has no cat. It's an '89 on a G plate... (or at least it was before it became a track day slag!)

[Simon]

As Dom says, it was an option on all E30's after 88, ony cars registered after Aug 1992 (K plate) legally require one.

[Simon]

Just had a look at the ETK and it shows 2 types of centre section, cat prepared and non cat.

[Russ]

Doms (my old one) had the cat, but i had it removed.

[Kedge]

Mine used to have one, till i needed a new exhaust.

Thanks great help.
So if I have no lamda sensor then will there be no cat?
Cheers

If there's no lambda then no there won't be a cat.

Andy - another easy way to check. Go to BMW dealer with the last 7 digits of your VIN number and get an original spec list print out. This will tell you whether the car was originally supplied with a cat or not.
