1994 Bmw 740i problems
The BMW 7 Series is a full-size luxury sedan manufactured and marketed by the German automaker BMW since 1977. It is the successor to the BMW E3 "New Six" sedan and is now in its seventh generation.
The 7 Series is BMW's flagship car and is only available in a sedan bodystyle (including long wheelbase and limousine models). It traditionally introduces technologies and exterior design themes before other models in BMW's lineup.
The first generation of the 7 Series was powered by straight-6 petrol engines, and following generations have been powered by inline-4, straight-6, V8 and V12 engines with both natural aspiration and turbocharging. Since 1995, diesel engines have been optional in the 7 Series.
Unlike the 3 Series and 5 Series sedans, BMW does not offer a full M model, but once offered an M performance variant, the BMW M760 with its 6.6L V12 (at the time the most powerful BMW ever made, not to be confused with BMW 760 6.6 V12 which does not offer the same performance). The Alpina B7 (G12) served as the high-performance variant of the 7 Series.

ENGINE AND ENGINE COOLING PROBLEM

- VIN: WBAGD432XRD
- Components: ENGINE AND ENGINE COOLING
- Summary: I HAVE LISTED A NUMBER OF COMPLAINTS THAT ARE EQUAL TO THE TYPE OF PROBLEM THAT I AM HAVING. TELL IF THIS TRUE AND WHAT CAN I DO. I HAVE A 1994 BMW 740I WITH 89,000 MILES. 1) 740I M60 SLIGHT SHAKING VIBRATING AT IDLE HELLO, MY 740I MODEL 1994 95,000 MILES (BUILT SPET. 1993) IS SHAKING A LITTLE AT IDLE. I HEARD ABOUT THE NIKASIL ISSUE, BMW SHOP SAYS THAT'S NOT THE REASON. THE AIR PRESSURE HAS BEEN TESTED FOR LEAKAGE (AT OIL FILL IN) AND WITH 2.5 (OF WHATEVER) IT IS OKAY, SAYS THE MECHANIC. 3.5 AND ABOVE WOULD BE BAD, HE SAYS. THEIR SOLUTION TO SOLVE THE SHAKING IS TO REPLACE THE ENGINE AND TRANSMISSION MOUNTS (890.00 US$ TOTAL), BUT I DON'T AGREE WITH THEM, SINCE THE SHAKING IS VISIBLE AT THE ENGINE BLOCK, AND THAT IS NOT NORMAL. EVERY NOW AND THEN (+-3 SECONDS) A SLIGHTLY STRONGER SHAKE IS NOTICEABLE. IT IS NOT REALLY DRAMATICAL, JUST ANNOYING, AND DEFINITELY NOT NORMAL, SINCE THE ENGINE DOESN'T RUN SMOOTHLY ROUND (MY DAD HAS THE SAME CAR, SO I KNOW HOW NICE IT CAN BE). RECENTLY THE SPARK PLUGS AND ROCKER GASKETS HAVE BEEN REPLACED. IF ANYONE HAS ANY IDEA WHAT TO LOOK FOR NEXT, I WOULD REALLY APPRECIATE COMMENTS! 2) THE PROBLEM IS LISTED AT HTTP://WWW.KOALAMOTORSPORT.COM/TECH/MISC/V8SHORTBLOCK.HTM TELL ME IF THIS MY PROBLEM?

1994 Bmw 740i recalls
The National Highway Traffic Safety Administration (NHTSA) has issued 2 recalls for different components of the 1994 Bmw 740i.
- Manufacturer: BAYERISCHE MOTOREN WERKE
- Components: VEHICLE SPEED CONTROL
- Summary: THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
- Consequence: THIS COULD CAUSE THE THROTTLE VALVE TO REMAIN PARTIALLY OPEN. IT HIS WERE TO OCCUR, THE CAR MIGHT NOT DECELERATE AS EXPECTED INCREASING THE RISK OF A VEHICLE CRASH.
- Remedy: DEALERS WILL INSTALL A SPRING STEEL CLIP ON THE OUTER TUBE OF EACH CABLE IN THE AREA OF THE ADJUSTING SCREW AND PLASTIC BUSHING. THE CLIP IS DESIGNED TO PREVENT THE OUTER TUBE FROM DISLODGING FROM THE BUSHING.
- Manufacturer: BAYERISCHE MOTOREN WERKE
- Components: EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH
- Summary: THE BRAKE LIGHT SWITCH CAN FAIL ALLOWING THE SWITCH TO REMAIN IN THE "BRAKE LIGHTS OFF" POSITION OR IN THE "BRAKE LIGHTS ON" POSITION.
- Consequence: IF THIS HAPPENS, THE BRAKE LIGHTS EITHER WILL NOT OPERATE OR WILL BE CONTINUOUSLY ON, REGARDLESS OF BRAKE PEDAL POSITION. FOLLOWING DRIVERS WOULD NOT BE ABLE TO DETERMINE WHETHER THE VEHICLE IS STOPPING, INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
- Remedy: DEALERS WILL REPLACE THE EXISTING BRAKE LIGHT SWITCH WITH A NEWLY DESIGNED SWITCH.
