Thank you for your advice
 
It seems it makes sense as I have been told the diag showed there was too poor or too rich a fuel/air mix in some cylinders. I will check when I am back in France ( the car is there)
 
The car is running OK. It is regrettable the BMW electrics are so fragile. I sometimes have some error messages saying the rear plate lights are not working (they are) or the coolant level to be checked (even just after a BMW-service).
 
I regret they don't take electrics reliability courses at Toyota's. They wouldn't have trashed the 2002 model this way.

#411 of 831 1994 BMW 740 IL - Hard starting...to...no start by bosox406

Jan 20, 2006 (6:22 am)

My 1994 BMW 740 IL (93-94, E32 model) won't start. This was slowly starting with the symptoms of taking longer and longer to crank over. I changed the spark plugs and even change all the ignition coils. It will crank, but not turn over. In the past, when it would eventually start it ran fine. It just started taking longer and longer to turn over until now where it will not start. When it was running I ran a can of BG44K through on a tank of gas. Any ideas I can check myself before unloading my checkbook at the repair shop?

#412 of 831 Service Manual for 2000 740i Sport by forrestl

Recently purchased the car and do most of my own work. Is there a factory service manual available on this model? If not, what is the best service manual available for this vehicle?

This may be a dealer only item and I'm not sure they even have a 7 series beyond 1994 (E32). It's not a car most people work on themselves, so probably not enough demand. Bentley Publishing does the best job for German cars but they only have BMW 3 and 5 series for year 2000 and up cars.

Funny how that check engine light keeps coming on. I just bought a 740il and within 24hours the check engine light came on and said coolant level needed checked. So we took the car back to dealer and he sent it to BMW dealer where they said it was a sensor and replaced it. Well, it has been one month and the check engine light came on two days ago and it went off today. My husband said to take it to the dealer, but it is two hours away and if the light went off, I'm thinking it is just a short or something dumb like that. I keep reading about the check engine light having problems. Hopefully it isn't anything serious since the light went off. How is a person to know whether to believe it or not???

Well it's hard to know because the engine light being on doesn't always mean you have to do something like RIGHT NOW...on some cars only if the light blinks are you in an urgent situation...not sure about your model...it would be worth reading up in the owner's manual to see if you have a check engine light with both a steady and a blinking mode.
 
Sometimes the engine light is activated by minor things like a loose gas cap.
 
Even if you read the codes the computer scanning tool doesn't tell you the defective component, only the circuit or system that is affected. So even if the dealer reads a code and is says "check the so and so", you still don't know exactly what the problem is. No car computer can do that (yet).

Thanks. That's what I was afraid of. Has anyone purchased a late model Series 7 service manual from a BMW dealer, and if so, what was the price?

#417 of 831 Front end noise by sunnboye

Jan 23, 2006 (8:20 am)

'97 740 IL, looks and runs great, 135K miles, when driving over 60 m/hr I get sort of a humming sound coming from the front end. Car has 2 week old Kumho sport tires, so I know it's not the tires.

See if the noise rises and falls in frequency as you speed up or slow down. See if it goes away if you shift momentarily to neutral and let the engine idle down (be SURE no one is behind you!). Try it on different road surfaces, such as concrete highway or smooth black asphalt.

I would recommend just checking on ebay for a Bentley manual (Bentley is the name of the company, not the Bentley cars) or Chilton's or Haynes manuals. You can probably find good deals on used books (or maybe CD-ROM, if you prefer).
