Read evidence and context
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: 'Disconnect however' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Disconnect however' (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.

Mates C4s can the 4 wheel drive be turnned off? To get roar feel 2 wheel drive.
I thought you could, but not sure.
Migration info. Legacy thread was 126992
Errrr no! It's permanent although the viscous differential will vary the amount typically it's 5% front, but can reach 40% under extreme conditions.
The front propshaft can be disconnected however
Migration info. Legacy thread was 126994
No (unless I am very much mistaken) - but only a very small % goes to the front wheels under normal conditions.

To be more precise:
PSM (Porsche Stability Management) is a far more comprehensive stability control system. PSM 5.3 was introduced as an option on the 1999 Carrera 4, and PSM 5.7 became an option on all models from MY2000.
"PSM is an active control system for stabilising a vehicle at the limit of its driving dynamics capability. PSM includes functions such as ABS, ABD, ASR (traction-slip control), EBV (Electronic Brake-force Distribution), as well as a longitudinal dynamics control system MSR (engine drag torque control). In addition to this, the vehicle is stabilised at the limit of its driving dynamics capability within the transverse dynamics control system by FDR (driving dynamics control system)."
Lots of nice acronyms for you to get your head around there!
