    I might be wrong, but i thought that they carried on the single vanos engines in the 5 series..

    I just noticed 25s63 are single vanos and 256s4 are double and they were both made up to 2000. So it all depends on the engine code.

    Correct....the 2000 model 523i has the M52TU engine with bi-vanos. Single vanos were available on the M52 Steve, but this stopped somewhere in 1998/99 when the technical update was introduced and the TU engine came out with double vanos
