hey guys new to bmws and forum please HELP lol
 

hey all i have just recently bought a m reg 325i convertible which untill yesterday has ran like a dream .... however !
after taking it thru the carwash lastnight it died on me on the way home, i managed to get home but as i pulled up on the drive it died again,
after a bit of cranking it started but the seemd to be miss firing on a cylinder or 2,
assuming it is water ingress i left it over night and it started fine this morning and has done since ( on the drive )
i read on a thread that this can be caused be the drain pipe on the air intake getting blocked and allowing water to splash the ecu area i cant find said pipe or a tread to point me in the direction of it any help wud be much appreciated

thanks ;)
