    Weird, but sounds like you have a large vacuum leak somewhere, like a hose popped off or something....certainly the symptoms are exactly like a large vacuum leak might exhibit.

    Are you satisfied with Warranty Direct? I have compared prices and Warranty Direct seems to be one of the best around as far as price. I just want to make sure that when you need them they will be there! The guy that does the work on my car has not heard of them.

    Thanks
  • There is a rumble by the right front tire, like a vibration, but it's only sound, no
    vibration. Also, there is another rumbling sound just under the front seats and an
    actual rumble near the backseat on the right side, but it is mild and it lags power
    when gas is pressed.

    During acceleration, it seems the left side picks up the power and there is no
    sound from the left, but by the right rear tire, it feels like the differential isn't
    producing enough power to the right side since I have to cut the wheel left to
    maintain driving straight. Is this just an axle or do I need a new differential? Or
    should I change out the driveshaft (since it sounds like its coming from just
    underneath the driver's seat)? It was in an accident, but it wasn't a major one and
    the car is structurally fine.

    I found on the left side 2 plastic, large diameter hoses and 1 on the right side,
    under the front bumper which are cut. Does anyone know where these hoses go
    to and what do they do? I also found what looks to be a small pump and part of
    the hoses connected to it in my trunk and don't know what that is. Is it the wiper
    motor for the headlight/ foglights? When I activate the windshield wipers, there is littlewater that sprays out of the hood sprayers, none out of the headlight or foglight wipers and there's alot of water that comes out from under the hood.
    When I activate the turn signals, is the side reflectors on the front fender and rear quarter panel supposed to blink or is this too old a model for it to have side blinkers? How do I fix this? Why didn't my diagnostic computer tell me about this?

    Also, does anyone know how to remove the rear window shade and brake light
    indicator from the back window? I have been trying to fix the window shade and
    replace the red glass on the indicator, but it doesn't seem that I have access to
    remove those panels.

    And lastly, where is the switch to activate the driver or passenger side vanity mirror
    lights? I have been trying to activate them, but I can't find the switches. As for the driver seat memory control, how do I program my memory selections in? Every time I try, they just go into some other selection. Any service information you can provide will be greatly appreciated.

    Mr. Shiftright,
    Are you aware of major problems concerning bushings (leaks) and rear main
    seal (leaks)? I just purchased this vehicle, a CPO with only 45k but am somewhat
    disappointed with these leaks. Otherwise, I like the power, comfort, responsiveness, safety features, and looks. My 528i ('97) had 105,000k when
    traded in on this 740il and I feel secure with the warranty. So, two trips to the
    dealer in 30 days is not good. Are leaks a major concern with this vehicle?
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,643
    Not to my knowledge...the front end bushings yes, they wear on most BMWs and your radiator will probably crack on the upper hose connection, but never heard of a particular leak problem on a BMW. On new Porsches, yes, but didn't hear anything about BMWs in that regard.
  • jackiebjackieb Posts: 4
    Thanks for the info. The radiator was replaced at 44k before I purchased the
    vehicle. The cooling fan and steering center link were also replaced before my
    purchase. What are some other potential problems down the road on this car?
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,643
    Probably your only other potential issues will be electrical glitches....the driveline is pretty bulletproof and you've already addressed the most obvious (to me anyway) weak points.
  • I know about the vanity mirrors. When the car is on the lights will turn on when the vanity mirror panel is slid open. I believe we have the same car so it should work that way. Maybe the bulbs or wiring connections? I'm not sure, I don't know anything about cars really, but my car does lag when you press the gas like when merging onto the freeway.

    First of all I must say that I completely love the way this car looks and drives. I am looking to buy a 02 745Li in the near future. Have been reading on this discussion board about problems with the car. Also have been surprised with some peoples experiences with BMWNA customer service ( post # 258 ) . My concern is that I am in my residency and currently own a 03 4runner which has been to the dealer a total of 6 times ( oil change and service ). I simply don't have the time to take a car repeatedly to the dealer for repairs.
    -How reliable is the '02 745Li ?
    -What are the most common problems with this car?
    -Which ones put the car out of commission for a few days and how often do they occur?
    -If you had your money back would you buy it again?

    Thanks for your input in advance.

    02 745 A/C problem. I have had my car in the shop 6-7 times for the A/C. every time i turn it on it smells liek a cat ha spissed in my car. The smell is horrible and they kep flushinh it and changing filters, but it never helps. It is in the shop now again and I told I do not want it back if you did what you did in the past. Has anybody had this problem? Resolved ? I am very sick of this and must say this car is the worst I have ever had. It would eb OK, if BMW would act on it. I have aclled BMW USA no call back. Besides this, I also have issues with cd player get stuck, window does not go up, navigation system, seat memory does not work, trunk would not close, engibe failure twice..

    HELP ???
  • keeskees Posts: 3

  • keeskees Posts: 3
    I noticed yyour messsage on the board. Since I cannot get any reply fro BVMW USA by phone, I am addressing you. I have an issue with the A/C. It just stinks very bad when turned on. the mechnics admitt that this is a problem with the car and they have flushed and chnage filters 6 times. It doe snot help. The car is in the shop now and I told them to keep the car until they fix it. No more filter chnages, I need something done for real. Do you have a solution for this? It has been very frustarting!!! And why doe snobody at BMW USA call me back . Twice !

    I purchased a used 2002 745 in March 04 with 19K miles. I had read many of the reports regarding quality issues and realize BMW's are not Toyotas(I have owned both before). Since March 04, the following problems have occurred. 1. Airbag Failure light(no found issues) 2. Passenger Window Broken 3. AC Never worked right 4. Navigation System-didn't work(slow) 5. Bells going off when the car is parked and key removed 6. Hum in Speaker 7. Air Seats not blowing properly 8.Radio not showing presets. The car looked and drove great. Couldn't stand all the problems..traded it in on a Lexus at 38K miles 11 months later. Lexus, 5000K miles no problems. I will keep my 1999 Z3, but will never buy another BMW. I heard the factory is offering a 100K warranty for 02 and 03 owners. It would be great If BMW would have sent that information to me(they didn't). Very Sad.

    I'm currently stationed overseas in Europe and just purchased a 1995 730i. The car is truly awesome but the owners manual is in German; is there anyway to get the owners manual in English via PDF file or purchasing one so I can truly understand all the features and capabilities of this great machine?

    Thanks
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,643
    I'd try eBay or have a friend in the USA buy one at a BMW dealer and send it to you. Keep in mind though there is no 730i in America, only a 530i. So you might have to try a dealer in the UK.
  • I just got a 1993 740il used and for the most part it has been great. I put a few things into it before I took ownership and the dealer was a friend of the family so he also did a few things that ordinarily would not have happened. The car is in mint condition inside and out especially for this many years old. It truly was a pampered car who ever had it. Ok, now the problem....Of late, every time I step on the brake the 1 Brake Light comes on with a bell sound. I check the bulb and the brake light is fine. After the car is turned off the 1 Brake Light sounds and continues to display. I guess at some point it goes off because it is not on when I get back in the car. As soon as I step on the brake I get the warning again. Why is this happening!!! The bulb is fine. I was trying to avoid a trip to the dealer because all of the early gifts from the dealership are through. Is this a prelude to electrical problems I have heard so much about with BMW's? Any advice I would greatly appreciate it.

    94' 740i with 140K. Always maitiamned and the transmission has developed a strong surge / firm shift when shifting into the 5th gear.

    Fluid has been verfied . Looking for thoughts to follw-up that may assist. BMW want to replace....

    Service company indicates it somewhat normal. Everyone has different thoughts.

    Any suggestions,
  • Do i need to change the Rotors if i change the Brake Pads.The car computer says check the brake linings.Pls Suggest.
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,643
    Depends on their condition. If they are worn down or grooved, you follow BMWs recommendations. They may require that you replace rotors and not turn them, I'm not sure on this particular model. Rotors aren't all that cheap for this car so I wouldn't just chuck 'em like you would with a Honda. Also you have a big fast heavy car and you don't want to cut corners.

    So to summarize:

    1. Does BMW authorize turning rotors at al for your model?

    2. Are your rotor surfaces in pristine condition or are they grooved or smooth but worn too thin?
