I did not grow up with BMWs. I am reading posts here and learning lots. I searched, but could not find a list that explains the various abbreviations and engine code you guys use so easily.
Is there a list...i need a decoder ring!
I know I've typed this before, but don't know where it is.
Chassis: E36/7 (roadster), and E36/8 (coupe). It's a derivative of the E36 ('92-'99 3-series).
Engines (just US Z3):
M44B19 - 1.9L 4-cyl ('96-'98)
M52B28 - 2.8L 6-cyl ('97-'98)
M52tuB25 - "2.3" (really 2.5L) 6-cyl ('99-'00)
M52tuB28 - 2.8L 6-cyl ('99-'00)
M54B25 - 2.5L 6-cyl ('01-'02)
M54B30 - 3.0L 6-cyl ('01-'02)
S52B32 - 3.2L 6-cyl ('98-'00 M)
S54B32 - 3.2L 6-cyl ('01-'02 M)
Then there are all sorts of other acronyms for suspension parts and engine parts. I'll start with some that come to mind -- feel free to add to the list, everyone.
LCAB: (front) Lower Control Arm Bushing
RSM: Rear Shock Mount (top of rear shocks)
SAP: Secondary Air Pump
I like the unicorns.
'99 Z3 Coupe - Jet Black/Black (1-of-114)

'03 540iT - Sterling Gray/Black (1-of-24)
'16 Z4 sDrive35i - Estoril Blue/Walnut (1-of-8)
RTAB: Rear Trailing Arm Bushing
Lollypop: Front Lower Control Arm Bushing Mount
Giubo: Rubber Drive Shaft Coupler (to transmission)
LSB: Laguna Seca Blue
FLCA: Forward Lower Control Arm or ‘Wishbone’
RTA: Rear Trailing Arm

There are three sets of acronyms in play.
BMW specific. Very precise, but sometimes don't make sense because they are German based. DME = engine computer
SAE. Again, specific and universal. This is what your scanner will show, and your mechanic will use. Rarely used in the forum
Forumspeak. This is a bunch of random letters strewn together based on what the poster thinks the part is called at the time. Ambiguous, vague, and sometimes contradictory.
/.randy
Some common forumspeaks:
NLA - no longer available
OP - original post (or poster)
AFAIK - as far as I know
IMHO - in my humble opinion
PITA - pain in the ass
LOL - laughing out loud
ROFL - rolling on the floor laughing
TU = Tango Uniform = broken

Seems to put US owners into some sort of fit.
