  • Might be worth it depending on the "exclusions" in the warranty. I'd spend a whole night reading it.
  • I have a 2001 740il.About two months ago I started it and by the time i got out of my neighborhood it was hucking and bucking and barely running and a check engine light was on. I pulled over, turned the car off and re started it and everything was fine and has been until this morning. On my way to work I stopped to get coffee and when I got back in the car and started it, it felt like I had little or no power steering. I pulled over, cut the car off and re started it and everything is fine. It's almost as if the car is running Windows98. Has anyone ever had a similar problem?

    Thanks,

    KDA
  • You need to have the codes scanned I think. There are so many things it could be. Could be sticking injector, bad plugs wires, bas sensor, etc. etc.

     

    You might try a can or two of dry gas in the tank just in case you picked up some grungy gas somewhere with water in it.
  • This message is for Mr. Shift Right. I finally got an estimate on fixing the leak from my heater core on my 1997 740I. My mechanic, said he would replace the heater core for me. The job will take approximately 2 days to complete. The cost will be 1,000.0 plus any hoses he has to replace, but the job should cost no more than 1200.0. The price at the dealer was approximately 2300.0. I hope this is going to solve my problem. I have to get it fixed regardless, even if I sell it or keep it. Just wanted you to know, that I didn't forget about u, and your advice. Thank you.
  • Well it's a shame you have to do that on a car only 8 years old. Heater cores, like radiators, do clog, corrode, etc. Maybe once they dig in there with the back hoe they will only find a broken hose or something.

    I own a 2001, 740i , which currently has 60K miles. Purchased as a Certified Pre-owned when it had 42K miles. The car has been great, no significant problems to speak of, except for one nagging item -- it appears to have what I would consider to be an excessive level of wind-noise coming from the sunroof area when the sunroof itself is closed, and the "sunroof panel" is pulled all the way back. The noise level is fine up to about 40 mph, however then increases significantly at 50 mph and above. When I close the "panel" it is much less noticeable, however whenever it is open, it sounds excessive.

     

    I have driven in a friends 97 7401, which seemed much quieter ... and even the 3 series loaner at the BMW Service center is quieter. The dealership replaced the sunroof "seal", however that does not appear to have helped much.

     

    Is this just normal for a 2001 740i, and/or is there some history of this problem, with common fixes identified. The dealership doesn't appear to "hear" the noise as much as I do, or so they say. All I know is that it is a heck of a lot noisier than any car I have owned before.

     

    Any advise/help would be appreciated.

     

    Thanks,

  • If you can observe that the roof is closing very tightly and evenly all around the seal, then your only recourse would be an aftermarket wind-shield of some sort---they work but they can be a bit ugly.

     

    Sunroofs are adjustable by the way. If you notice any un-evenness around the sunroof seal when it is closed, this can be adjusted out.

    Mr. Shiftright -- thanks for your response.

     

    From all appearances, it does look like the roof is closing tightly and evenly, so that is why I don't quite understand the wind noise. I thought the new seal would correct it. Maybe as you have suggested the Sunroof needs to be adjusted somehow. Is this an issue that has been seen with any frequency that you are aware of, or does it just sound like a one-off problem that I am having. For all I know, it could be normal for 740's to have a bit more wind noise, although I doubt it. My old Mercedes with over 200K miles was whisper quiet whenever the sunroof was closed, and I would expect at least as much from

    BMW. Anyways thanks for your response ... I guess I'll take it back to the dealer for another look.

  • It might not be quite snug enough. Are you talking about a 'whistling' kind of noise, high-pitched, or a very low, loud "drumming"?
  • mjc3mjc3 Posts: 3
    Mr. Shiftright:

     

    The sound is more of a higher pitched whistling noise. I took it back to the dealer today & had the foreman out for a test drive. He confirmed that it did seam a bit louder than normal, although not significantly in his opinion. So he took it back in the shop and did some re-adjusting make sure it was settled in full compliance with the specs. The result -- a bit better, however still not what I would expect for a higher-end car. I'll probably take to another dealer next week to get a second opinion.

     

    Thanks,

  • Hi George,

     

    First off, please turn off your CAPS LOCK. It's hard to read and it sort of violates online courtesy. Many folks will simply not respond to posts done in CAPS LOCK.

     

    But I will, just this once!

     

    I don't think I'd touch the trans unless you can look at the fluid and inspect/smell it. If it looks VERY dirty (like mud instead of pure and clear red) and/or smells like burning cork, you might want to drop it out. I don't see any harm in changing the oil and filter if it is dirty.
  • Hi All,

    I'm thinking about buying a '00/'01 740 sometime this upcoming May/June. I'm comparing this with a same year LS430/LS400 and S430. I'm already leaning towards the 740, but I'd like some of your opinions in the matter since I don't have much 1st-hand knowledge/info (yet) in this class of cars. I know that quality wise each individual car is different.

    I have done the basic research on Edmunds, so I know that the S was new for '00, and the LS was new for '01, but I still like the 7. I know the 7 is new for '02, but that's a little out of my price range.

    I guess I'm looking for why you would buy the 7 vs the LS or S.

    Quality/Reliability? Handling/Performance? Styling/Image?

    Thanks everyone!

    (This is my 1st actual post, although I have been browsing these forums for some time now.)
  • My personal opinion is that the BMW beats the Lexus mercilessly in all categories you mentioned except reliability. The BMW will probably have little burps and glitches and probably cost more per mile to run.

     

    I've driven both these cars and again, I personally would put up with an occasional spit up and temper tantrum for the benefits of having a car that is much more exciting to drive and a lot more fun to look at.

     

    But if you willing to trade off these things for the edge in reliability, then the Lexus would work better for you.
  • Thanks MrShiftRight.

    What do you think about the 740 vs (MB) S430 comparison?

    I agree that reliability wise (overall) Lexus probably edges out both BMW & MB, but loses in styling.

    Comparing BMW vs MB though would seem to be a little more difficult.
  • I still think the BMW is a better driving car in every respect than the MB. I think the engines are better definitely.
  • hello everyone,

    i am a new member.

    i just bought a 740 il sport and i am considering to buy the extended (platinum) service warranty. the coverage is for 36mos/36k miles for $3,300 with a $150 deductible. what do you think of it.

    since the car did not come with the owner's manual, i am having difficulty learning to operate its options/equipments. any idea where i can obtain a manual.

    comments and advise are highly appreciated.

    mahalo
  • The dealer sells the manual and probably has it in stock.

    As for the warranty---how many miles are on this car already? Also, I would strongly suggest you read this warranty cover to cover so that you know exactly what is included and excluded.

    You can run up a $3,300 repair bill pretty easily on a 740, especially if you drive a lot.

    If you are out of factory warranty already, it might be a good idea if the exclusions are not too many or too severe.
