VANOS on a 530?
Hi folks,
Does a 530i 2001 have VANOS system or no? when was it ontroduced? what about double vanose. I am actually buying a 530i 2000 in germany. but since it was introduced in 2001 in usa i am asking the question for a 2001 one. I guess a 528i 2000 does not have VANOS technology.
thanks

Yes. The 530 has the M54 engine. And thatīs allways a double Vanos unit. The (late) 528 is an M52TU. Thatīs either a single (intake side) vanos or a double vanos as well (not entirely sure on that one)

M52 is a single vanos unit on the intake. The M52 is an evoluton of the M50.M54 is dual vanos As far as a 530i, dont be confused with valvetonic, which is a variable valve lift and timing system, which is only available on the 04+ 545i, 745, 06+ x30i's and x50i's.

I beliee this engine was introduced in 99 to coincide w/ the relase of the e46. The M54 didn't change much over rhte m52tu except newer engine mgmt computer, different intake and exhaust and something about a revised coolant flow to help the engine get up to temp faster (don't remember the details). HTe primary purpose of the M54 was to maintain performance levels while improving emissions.

Thanks for the enlightenment though.
