981 profile
1800FF00Verified on a real 981: DME is KWP2000. 18 00 FF 00 reads the fault memory (returned P000C); UDS 19 is rejected (7F 19 11). Clear (14 FF 00) is the logical counterpart, untested to preserve a live fault.
987 profile
1800FF00Candidate — the 987 DME is likely KWP2000 like the 981; confirm 18 00 FF 00 on a real car.
991 profile
1902FFCandidate — newer 991 platform likely UDS (ISO 14229); confirm 19 02 FF on a real car.
