Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'Check car's build sheet and no lsd' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check car's build sheet and no lsd' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

It was only available on 99s and 40th anniversary editions. For the 99s, I believe it was usually coupled with the DTC option. It's not extremely rare amongst 99s, but that still makes it rare among 996s in general. I wouldn't want a 996 without it.
220 is definitely the option code for LSD, but I don't think I've ever seen it on an '00-'04 (40th anniversary excluded). Mind posting a picture of the option code sticker as a record for the future? I would like to be proven wrong about the LSD being unavailable on the e-gas cars.
Unfortunately, tampering with the LSD would bump me out of my SCCA autocross class. I have often wondered what the car would be like with a proper one, though.
You can have your LSD serviced; the disks & ramps are wear items. Guard makes nice parts that seem to last longer than the Porsche or Porsche Performance. It really wakes up your car to have the LSD function as it did when new.
ALE, I thought about this while I had my transmission out yesterday during the clutch job. I unfortunately have neither the time or money for it right now, but I would like to rebuild it myself at some point. I would have to use OE parts or parts there were basically exactly the same as OE.
Had a second look at the option sticker under better lighting and looks like knfeparty is right. It's 238 & 288.
Also I checked my car's build sheet and no LSD. At first I was feeling bad but I think someone said option code 220 is not a performance LSD so I don't feel as bad.
This is a source reference. Confirm exact model applicability in the original material.
