BMW 7-Series Maintenance and Repair



  • I give up, I am going to have my buddy take it into the dearlership this week, and would be happy to report back

    Been thinking through this one after week of observations. Must be some kind of fuse that trips for the nav system when hot? Should not be a computer problem as you (I) can still access info on the dash. Therefore the main? computer is still receiving and sending info. Seems to work fine when first initialized, then after 20 minutes or so, screen locks up, radio turns off, etc. Was on a long round trip yesterday and paid close attention to the interval of radio shutting down. Every 3 minutes exactly. Must be a fuse or nav computer software glitch. I'm going to try and upgrade in software to see if it's a fix, then fuses, then hard reboot (disconnect power source) Will let you know if this is a fix.

    I have a 2002 745i and the idle was going below 500 rpm at times, especially at stop lights, signs, etc. Even though it was smooth during driving, the drop in rpm was annoying and it seemed as though the engine would shut down, then jump back up to 600 rpm. I took it to my local BMW dealer and they adjusted the idle to 700 rpm at rest. I haven't had any problems since. A simple fix. Otherwise, could not be more impressed with my Bimmer!!!!
  • rvorbaurvorbau Posts: 3
    UPDATE...May have found the fix! Downloaded version 26 software upgrade, followed instructions for the upgrade exactly, and now(cross my fingers)the problem seemed to fix itself. Will see how it goes in the coming days.

    Thanks for the reply. I will relay this information to my dealer. The car has been with the dealer since last Saturday and the dealer is working with BMW b/c they cant seem to figure it out.

    Also, does your rpm slightly jump up when the AC is on? When my AC is off, at rest my rpm is sitting at .5. Once the AC is enabled, the RPM jumps to about 0.7 (and stays there till the AC is disabled). Just wanted to know is this was normal or not. My wife has an 01 X5 and this behavior doesnt occur on her vehicle.

    I can't see why BMW has to keep your vehicle for such an extended period of time just to check the idling issue - seems strange. At one point before my local dealer fixed the problem I had with my car, the tach needle was "idle hunting," going up and down below 500 rpm, especially when I had no auxiliary equipment in operation (A/C, defroster, etc).

    My rpm does increase to a little above 700 rpm when the AC is on, and once it is off, the rpm goes down to around 600 rpm. I believe this to be normal due to increased load on engine when the A/C is turned on.
  • sadatxsadatx Posts: 70
    So I called my dealer asking if the tech has tried adjusting the rpm at idle to 700 rpms at rest. Service rep indicates that the tech working on the car is the best they have and is pretty sure he's tried it - whatever. Service rep mentioned they have a pullman case opened (not sure if I heard him correctly though - could be called something else) with BMW on this issue.

    At least the dealer gave me an 06 530i (as a loaner) with the sport package which handles great. Now I regret (and only regret so far) not having the sport package on the 745. Vehicle still handles great, but Im sure the 7 woulda been a lot more nimble and not feel like the boat it is w/o the sport package. Next 7 series I purchase will definitely have the sport package.
  • cjennjrcjennjr Posts: 7
    Hope you get the problem fixed, even though driving an '06 5 Series isn't bad either!

    The sports package on the BMW's are the best - firm, yet comfortable ride, and with the 19" wheels for the 7 Series, the look really catches the eye, especially chrome 19's!!

    In some cases the warranty for an 02/03 is 6yrs/100k. Not sure so check with your dealer. Lost of times its an software update. Let us know what happens as I was thinking about trading in my perfectly good Lexus for a 745, but I can't bring myself to do it given the ongoing issues with these models.
  • kevin3344kevin3344 Posts: 5
    I went to LeighBMW in Raleigh last week and thought about trading in my Lexus for an 03 745. I took the 745 out for a test drive, and honestly it was the best car I’ve ever driven. From what I’ve been reading, however, it’s not the best to own. I can’t even imagine having some of the minor problems owners incur, let alone a major one. The car had a little over 40,000 miles on it, and the salesman told me about the 6yr/100k warranty, but I can’t bring myself to purchase the vehicle. I keep thinking, what if this car turns out to be a lemon, and I traded in a perfectly good vehicle with no problems? For the price, the 745 should be much more dependable.
  • sadatxsadatx Posts: 70
    Hi Kevin,

    How was the 745 a better driving exp compared to your Lexus? Did your 745 come equipped with the sport package? I'm really picky when it comes to wind noise etc, and I think my buddies lexus has a quieter cabin than my 03 745Li (but barely). And when my car is idle, it is definitely not as quiet when compared to the Lexus. Of course when I drive my car, the driving exp is a lot more enjoyable :)
  • kevin3344kevin3344 Posts: 5
    Hi sadatx, there was a little more road feel with the BMW, but I haven't decided yet on whether to trade my car in just yet. To tell you the truth, I'm a little concerned after all of the reading I've been doing. My friend has a 325i and he's never had a problem with it. Of course, it doesn't have the iDrive and much of the technology the 745 does. What has your ownership experience been like with the 745? It will need to be a lot more dependable for me to make a move. An extended warranty is one thing; but time and inconvenience is another.
  • sadatxsadatx Posts: 70
    Hi Kevin,

    Ive had my 745 for abt a month now (but its been with the dealer for 2 weeks of the one month ive owned it). I took the vehicle for regular service and a few minor issues. turns out one issue isnt so minor (an rpm issue). dealer cant seem to figure it out and is working with bmw on the matter. aside from that, its been fine. but i wouldnt be a good example considering ive only had the vehicle for such a short period of time. two of my buddies also has 7 series. one has an 02 745Li and the other an 03 760Li. both are happy with their vehicles but they do mention the glitches of idrive, etc all the time. my wife has an 01 X5 and its been great. only time will tell if my 7 will be good to me.

    Hi sadatx, let me know what happens when you get it back.

    I went back to Leith BMW today to test drive a 02 and 03 745. I asked for the Vehicle History Report on both autos, which my salesman provided. The 02 had a history of 18 service issues. In the comment section of the report there was an entry that read: “Bmw trade assist vehicle, ineligible for intial enrollment in bmw cpo program in CA or states with similar restrictions”. I’m not sure what that meant, but it wasn't something I wanted to see.

    The 03 745 had a much better history and drove much better. There were only 6 service dates which looked like normal service dates; for the most part the car was in and out of service in two days or less. Just what I wanted to see. However, we could not meet on the price. The car was on the lot for $49,999, dealer came down to $47,500, I offered $45,000. Maybe I'm asking too much, not sure, but I think that is a fair price for a cpo 7 (?)

    I hope you can enlighten me as to how often brakes need to be replaced on our 740Il. We had them done 20K miles ago (7 months) and now the brake lining lights message is coming on? I need help! Thanks!

    Hi Kevin,

    I got my car back finally. The dealer recalibrated thirteen modules (not sure what that means) and so far, the issue hasnt surfaced. Im gonna give it a few weeks or so to ensure the issue has disappeared.

    I would stay away from the 02 you drove. From reading the comments, I think the vehicle wont qualify as having a clean title.

    The 03 you drove has a similiar service history as mine. I would also look for any paint work (from previous accidents, etc), misaligned chrome trim (if this is not the sports package) on the bumpers, etc. What options did the 03 have? How many miles? I think your offer is reasonable - the 7s dont exactly have a waiting list :) I paid $45,500 (dealer had it listed for $52k) for an 03 Sterling Gray/Black leather combo that had 22k miles. Options on my vehicle were:

    * Convenience Package
    * Luxury Seating Package
    * Premium Sound Package
    * Tire pressure monitor
    * 19" wheels w/performance tires
    * Park Distance Control

    I bought it from a VW/MB dealer b/c I couldnt find black leather with low miles for the life of me from a BMW dealer! So technically, my vehicle isnt a CPO BMW. I wasnt to concerned with the CPO stamp as I was with the additional 2yr, 50k mile warranty (which applies to most 02s and 03s). I emailed BMWNA prior to purchasing the car to be certain the vehicle qualified for the additional warranty - and it did :) I also had to sacrifice the promotional financing that BMW was offering (maybe they still are) on the CPO 03s. They were offering 3.9% for 5 years. I ended up paying 5% thru my credit union.
  • kevin3344kevin3344 Posts: 5
    Hi sadatx,

    Good to hear about your car. The 03 I drove had comparable options; lux seating, logic 7, park distance control. Very nice when backing up I might add! The list was $49,999 with 40,100 miles. I went in knowing I wanted to spend $45k. The dealer came down to $47.5k, which was close but not close enough. I thought he could come down a little more to tell you the truth. The financing had just went up to 4.9%, which still wasn’t bad, keeping in mind the Fed had just raised the rates and I knew it would trickle down. But like you mentioned, it was 3.9%. Pretty good in this interest rate environment.

    I must say the service history on the vehicle was great, in comparison to the 02. Someone told me the 02 was probably a buy-back by BMW and I should avoid it at all costs. Going by the service history of the vehicle, I certainly will.

    As it stands now, I’m going to wait and see what happens. He has several 2003 745s on the lot so I can afford to wait a bit. The saleman told me “well, these might be sold next week” but for two weeks in a row when I have driven past they are there. Every once in a while I might see one missing (out for a test drive maybe?) but for the most part they get them in regularly on trades. I also check the Leith BMW website and look at the inventory. When I see one I like I will definitely check it out.

    I can't seem to get the grin off my face. :shades: After extensive research and patience in looking for a 745 I finally pulled thr trigger today on a low miles 21K 2003 745 for around 40K. Clean history and maintenance records. Theres one problem tho' the trunk doesnt open either from the remote or the switch inside the car.

    What could be the problem? Taking it to the dealer tomorrow to see whether they can fix it. I hope so.
  • newbie225newbie225 Posts: 1
    That looks like a great deal. Can you tell me where you've got such a great deal. Currently I am looking around and found one place for 03 745Li with 17k miles for around $52k. After your deal this doesn't look too good.?
  • 73,000 miles and the computer board that handles the navigation and cd player, and radio is out to the tune of a new board from East Bay BMW for 500 bucks! anyone else have this problem?
  • kuwait06kuwait06 Posts: 1
    just checking to see if anyone has heard of husband say when he turns the steering wheel to the left he hears some kind of noise that sounds like air coming from the one of the tires????..we just got it serviced less than a week ago and nothing was now it going back again!!!
  • I have 2001 740i with 59,000 on it. Last night i was using Navigation and by accident clicked on emergency option on the screen. Nav showed me my location and then screen went blank. I turned off the car but screen would not come back. Radio, cd etc. are working ok.
    I took out Nav DVD disc and turned on the car, screen came back. I turned off the car, put the DVD disc back in and turned the car on. Screen was blank, grey with white lines. I then tried taking DVD out again but it would not come out.

    Just wanted to know if anyone run into similiar issue and how it was resolved. It sucks that my certified warranty run out in June.

    Thanks for your help.
  • I've researched some aftermarket shops and have found angel eye bulb replacements for BMW 745s 2002 and up. The bulb give the look of HID like the headlight, not the yellow halogen light that it currently has. The question is, does anyone know where the angel eye bulb is located within the headlight module and how to replace it? I've looked over the Internet but can't seem to find any info regarding this. Any help would be appreciated.
  • I followed the 7 Series boards for many a month a couple of years ago when I was considering a new car. It seemed like everyone was having massive problems with the new style 7 Series and it was clearly star crossed. I bought a Porsche instead and love the great customer service and the fact that there is no unscheduled maintenance.

    I'm still puzzled though why people still want to buy these things. A quick scan through these boards reads like the Land Rover boards: most people love the cars, pay up for them, yet the ownership experience is awful! While the Rover thing is utterly baffling (a 70 MPH lane change in a Disco is a white knuckle experience while the ladder frame chassis takes a set and the roof decides much it is going to lean over) , I do understand how nice a 7 Series can be on a good day when the computers are all working, the I Drive in intuitively clear, and it is sunny out. But still, why do rational people buy such a problematic car?

    Moreover, I can't understand the Bimmer resale values. Everyone agrees that the car has lousy reliability. Yet, a used new style 7 Series is still close to 40K and the car is 4 to 5 years old. Are there that many people out there that just have to have the Bimmer brand, to heck with the underlying value for the money equation?
  • I have a 2002 745i, and I would agree that BMW's reliability isn't in the same league as Lexus, but they did realize the problems they had with the new 7 Series and extended the "new vehicle" warranty for another two years and 50,000 miles for '02 and '03 models. What other luxury marquee would do that?? I was in the market for a Mercedes S430 or S500 before I bought the 745. One of the many reasons for buying the Bimmer was the extended warranty - MB offered one at additional cost. Kelly Blue Book ranks BMW as the best in residual value over 5 years. Also, I think I can say with certainty that Bimmers are better in reliability than Mercedes, especially in recent years. Audi, I really can't say. Additionally, the technology is unparalleled (look at the new Benz S550 - they reek BMW inside and out!), the look of a Bimmer is unique, the interior is simple yet breathtaking, and most of all, they are FUN TO DRIVE!
  • OK, thanks for the reasonable response (I had expected an ad hominem attack by a cool aid drinker). Sure, the Lexus IMHO is a Buick made in the Far East, no one is really old or fat enough to want to drive around in an isloated S550 and lord it over his employees/clients/customers/vendors/neighbors, and Audis haven't been a paragon of reliability.

    I guess that leaves reasonable people like you (and me) who want a high end lux sedan that is fun and will handle with a short list to choose from. Don't forget about Jag though: great reliability, great pricing, and it is significantly lighter and nimbler than a uber German sedan. Resale? Lousy. But you can work it in your favor by buying an '05 for 42K as a CPO.

    I found a 1990 735i sedan, needing some interior repairs, but overall very nice for $1,300. Aside from that, it needs an engine which I can have purchased and shipped for about 1,000.00. Should I purchase this car or not?
  • No. Here's why. Rather than figure that for $2300 you are all done (or at least partially there), figure what a 1990 in geat shape would cost. Maybe 4K? Thats the better deal because you have no way of knowing right now what else besides an engine (and speaking of engines, what could possibly be the warranty on a 17 year old used engine?)this jewell needs.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,564
    Absolutely not. You can buy these cars all day long in very nice condition for $2,500--$3,000. The 735 is a very good car and there are plenty of them around in good operating condition. I wouldn't take that car you want to buy for free, quite frankly. Save yourself a nightmare.

  • I was able to temporarily solve the problem by:
    1. Disconnecting the battery for 10 minutes
    2. Taking out Nav DVD
    3. Putting DVD back into reader

    Everything worked ok for about 2 days and then Nav screen went grey again while i was
    driving. I reset the computer (see above) and screen started working again. But this time
    radio stopped working after about 5 min. I had to turn radio off and back on again. It worked
    for another 5-10min and then stopped at which point screen went dark again.

    Any ideas/suggestions???
