BMW 7-Series Maintenance and Repair



  • How about checking on this for me with (2) 2001 740i models, one with 3/00 production date and one with 12/00 production date. This is concerning the telephone interface issue.

    Hi everyone, I have a 1994 E38 730i and it has just one tiny problem: every so often the brake lights stick on. It's not the switch, that's been checked and on the diagnostics machine no fault comes up. The local dealer wants me to pay £75 plus VAT per hour to have an apprentice check it out until he finds something or nothing. Not a hope of me agreeing to that one. Anyone had a similar problem?
  • I paid $400 a few months ago for a pump. 3 days ago my 1990 735il would crank but would not start could it be my fuel pump again? :(
  • my bmw cranks but won't start.I'm wondering if anyone have any suggestions
  • I have almost exactly the same problem. I've had some kind of electrical drain that has caused three battery replacements in the last 5 years. I have a 2001 740i with 105000 miles. All the miles are highway. The battery started failing again a month ago, the trunk softclose stopped working, the trunk open warning went off as soon as the car started moving, and the car alarm would not engage properly - but the navigation screen continued to work! I brought the car into the shop (Prestige BMW in Ramsey NJ) for a regular service. They replaced the battery, performed a normal service, fixed a number of other items and detailed the car. When I started the car on pickup, THE SCREEN WAS BLANK but backlit. This was rather upsetting. This was a GLARING issue and one they should have caught before I drove all they way out to pickup the car (it's a 45 minute ride between my house and Prestige BMW). My service representative (Jason) was very apologetic (obviously) and suggested the I drive the car for a couple of days and perhaps it would clear up on it's own.

    On my way home, about 20 minutes into the ride, the screen started to flicker and came back partially. It was shifted to the right with a blank non-backlit strip down the middle. It also had lots of wiggly lines flitting across the screen. Over the next couple of days the wiggly lines stopped and I was left with a split screen (shifted right) with a 1.5 inch blank strip down the middle.

    I brought the car back to Prestige BMW the following week. After a couple of days of diagnosis work they called me back with the BAD NEWS. THE DISPLAY WAS SHOT. However, that is not really the BAD news. The BAD news is that THEY decided there was nothing THEY did to cause this. It was all just an unhappy coincidence.

    To compound that, the replacement part is $2000 and the labor quoted at between $200 and $300. The initial deal they offered was for me to pay them their cost ($1500) and they’d pickup the labor. There is NO WAY that this part just coincidentally happened to fail while it was in their shop. To me, it doesn’t matter whether or not they know what they did to cause the failure, they should still be liable for the damage. I’m going with the preponderance of the evidence – and I don’t believe in coincidences.

    After walking up the management chain a bit, I got them down to $1200 (my cost) to replace the screen. This is basically splitting the full retail cost down the middle. Although a closer look will reveal that they are eating the labor (~$150 their cost) and paying $300 of the $1500 cost of the part. They pay $450, I pay $1200.

    The fact that bmwthad has almost the same problem makes my case stronger. I strongly believe there is a FLAW IN THE DESIGN of the 2001 740 that makes the navigation screen vulnerable to battery voltage and current fluctuations. If I can find other similar issue in 10 minutes of searching on the web (Thanks bmwthad) then BMW has to have seen this problem. At a minimum, there should be a service bulletin that helps the technician avoid this failure when changing the battery and perhaps even a recall to fix the problem.

    And I still think they should have replaced the part a no cost to me.

    I’m interested in what others think about this and welcome any recommendations regarding how to pursue a more equitable resolution.
  • Clue: I recently spent a great deal of energy, time and $ on the check engine light in my 2000 X5. The oxygen mass flow sensor (something) was finally replaced and fixed this problem. I could not get an emission sticker and therefore could not renew my tag with this light showing.
    It took a very good private mechanic and his mechanic buddy's shop to figure this out.
    Ouch. But all better now.
    I still would not drive another make.

    I own a second hand BMW 740I with which has 89,000 miles on it. the service engine light just came own. I was told after the 60,000 mile service, that the next service was 100,000 miles by the BMW agent. If this true or I have to get the service done at 90,000 miles to get the service light swtich off

    Yougot an awesome deal. I bought a black 2001 740 I with 70,000 miles on it for $24,000 back in march.

    I now have 85 on it and I have had no problems with it. The only annoying this is the cup holder.

    How many miles intervals do you change your oil? 5K or more?
  • My 1994 740 iL transmission just quit (103,000 miles on the car). It has been explained as a problem with a ball that moves to a different place for drive than reverse. When I go into drive, it is like the car can't decide whether to go back or forward, so it just goes nowhere. Works OK in reverse.

    Dealer and usual repair shop say replace. Local transmission shop thinks a rebuild will work.

    Any thoughts?

    No! This is a common problem and USUALLY a "valve body repair kit" can fix this---it replaces all the little springs and detent balls in the valve body. A tedious job but often repairs the problem and a lot cheaper than a new/rebuilt transmission.

    I had the same problem; a Version 25 (V25) software CD has to be loaded & installed where the Nav CD goes. This CD is a spacial tool that has been sent to all BMW dealers. V26 is also now out.

    mr shiftright or others,

    I want to replace the brake pads on my 2001 740i w/ 69000 miles. I do not care for the local BMW dealer and am looking for an independent in Memphis. Can I use any premium aftermarket pad or is the OEM pad superior? Suggestions? price paid for job?
  • See message #343. Similar problem with 1993 740iL.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,404
    I think any premium German pad would be fine. Be prepared however to replace the rotors if they don't meet minimum thickness or are roughed-up. You don't want to be cutting rotors on a car of this size and power. If you needed four pads/four rotors you could easily hit $1,500--just pads, maybe $300 per axle something like that..

    I have the exact problem witht he radio and nav system. Wondering if anyone has sourced this out and found a solution?
  • kdubbskdubbs Posts: 1
    hello all. I purchased my 740i about 6 months ago.
    And I noticed that it had 3 garage door opener buttons.
    Unfortunately there was no manual with the car.

    So I have to use my Genie Garage door opener (which of course is bulky and messes up the over all interior look of the car).

    I was planning to purchase a manual, but in the meantime can anyone help? THANKS

  • mimeomimeo Posts: 10
    You can download or view a .PDF version of the owners manual in the "owners" section of the BMW site. Much easier/ cheaper than buying manual.

    Thanks to Mr Shiftright for brake pad info!

    >"You don't want to be cutting rotors on a car of this size and power."

    You mean cutting them below minimum, right? As long as the rotor is within spec, do you think there would be a problem with grinding them?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,404
    I'm not even sure BMW allows you to cut rotors on that model no matter what....I suppose you could clean them up a little of course but if I recall there is no cutting allowed even if you make it to spec. You'll need to double check that but I personally wouldn't cut rotors on a car like a 7 series unless I really needed to be economical (and I've had to do things like this now and then).


  • My problem is that the knob to use the navigation system doesn't fully work and I don't think it is a mechanical problem. Are you saying that the software CD you referred to is able to fix some of the problems we are having with the Nav computer?
