The funny thing is my 2002 has the picture inside the engine bay of the air pump and valves but nothing is i9nstalled on the engine? this car wa spurchased in washington and i am currently trying to get the car to pass smog. Does anybody have any advice. The smog tech said i need to install the airpump and all the tubes in order to pass.

Have you just considered slipping the dude at the smog station a $50? I know many people may be shy of attempting to bribe a gov't employee, but I doubt he personally cares whether the car passes or not.

There is a 49 state version and a 50 state california version. The sticker, if it still exists tells you what car you have.

There are few Cali board members who can help you out with your questions and get it to pass smog.

From what I hear you can't just "slip a dude a $50" anymore.

All USA '76 2002's have air injection wether 49 OR 50 state cars. It is the EGR system and Thermal Reactor that is deleted on 49 state cars.

  • That being said the air hoses are usually only available from a BMW dealer or Maximillian Importing...
    The air pump is available rebuilt from most auto parts sources.
    The main and adjusting brackets are best bought used from a specialized BMW Dismantaler like Double 02 Salvage in Hayward CA.
    The Air pump diverter valve is very hard to come by and is NLA from BMW

Here are the parts diagrams with all the #s you'll need



Last but not least you need the correct exhaust manifold with a fitting in the front for the air injection pipe to enter the exhaust stream.

I have many more 74-76 2002 smog parts and opperation answers if you have any more questions...

non-complying car past the CA test would be to have an identical car available to put on the dyno, AND find a smog tech that would be willing to risk a huge fine, loss of his smog license, shutdown of the shop where he's working, and possible prosecution to run a test on that car while putting your license & vin #'s in the computer (the emissions dyno's computer is online with a state database during smog checks, and either issues an electronic certificate to the DMV if the vehicle passes or logs a failure if it doesn't).

From what I understand, the CA BAR (Bureau of Automotive Repair) and ARB (Air Resources Board) run regular "undercover" checks of shops around the state, verifying that shops are complying with state regs - a shop that was caught circumventing smog regs would probably be out of business immediately.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
