2F08 är ett fel som lagrats i din BMW:s minne (en ISTA-felkod, inte en standard OBD-II P-kod).
Vad det betyder: DME — intake air temperature (IAT) sensor signal implausible. On most engines the IAT is built into the mass-air-flow (MAF) sensor. Usually a dirty/faulty MAF, a loose connector or an intake/vacuum leak — can cause rough or jittery idle. Not dangerous to drive; check/clean the MAF sensor and its plug, and inspect the intake for leaks.
