    will i find everything I need in a US printed 7 series owners manual for a 730i. I understand that the 730i is not available in the US but will the manual cover the specifics? if not what would not be covered?

    Well what I meant was you won't find a US printed manual for a 730. You might find a UK printed one however.

    I'd have to do some research, as I'm not sure how a 730i differs, having never seen one.

    Hi all

    I returned to my UK 1997 740i today to find that I couldn't open the central locking with the remote. No problem, I thought, it's probably the battery in the key fob, so I will just open the door manually. However, no dice, the key doesn't open the drivers door, the lock just turns, although the boot will open. There seems to be power in the engine battery, but I'm still locked out ! Does anyone perhaps have anything to suggest ?

    Thanks in advance

    I have a 90 750il that has a transmission problem. When driving, it seems that it takes quiet sometime for the car to go into gear. I had the oil change and transmission fluid checked four months ago and was told the the transmission fluid was full. I haven't noticed it leaking. Is this a major expense and is it worth it? Please advise.

    Hi everyone,
    First of all I want to say that this is one of the most informative bmw web-forums I have ever across with oddles of experiences and anectodes shared by various bmw vehicle owners. I just want to say keep up the good work :)

    I am a proud owner of a 750iL 98, with about 37K miles, yes I know thats ultra low but I drive it really less, its practically brand new. Never driven in winter, maybe I'll break that record this year who knows ;)

    Anyways I live here in Toronto and its been really hot lately these past couple of days... and whenever I go for refueling....its a mission in a half to fill up the gas-tank. :( ....I mean as soon as I put the noozle in the pump clicks in the first 2 seconds! :mad: I gently pull it out so only the top portion of the nozzle is submerged in the fuel tank ....again :cry: same thing the pump clicks....and it keeps doing it through out .....its sooooooooo embarassing driving a 7 series benchmark and this sort of thing happening everytime I go fill up on gas. I get all service done from the dealer the service rep said its normal and that you should pull the nozzle out gently and pump in that way....but hey thats what I've been mentioned earlier....

    I dont know what to do.....they said everything is normal....the mechanic voluntarily agreed to come with me and show me at the gas station how to do it...but I havent gotten the chance to meet up with him yet...however I want to know is there any cure for this?
    is this normal?
    am I in a very hefty expense?
    Can I use one of those fuel additives and put it in next time I fill-up to get rid of the air pockets?

    Sorry about the long post....please I need someone's opinion and advice as to what I should do... I mean I love the car its in immaculate condition and still has the new car leather smell in it....even after 7 years! and I hope there is a practical easy solution to this problem

    Kind Regards

    Hi, First time user,
    I have a question: My 1994 740IL, has a vibration when I reach the speeds of 52 - 55 mph, it is in the front. I replaced the original rims with rims from a 5 series that were alloy, same vibration, then I replaced the rims with chrome 17" mags. It didn't vibrate as much, but still there is vibration at the posted mph I mentioned. Any thoughts guys?

    Hi there f1buick,
    I have been there in your boat with my Lexus GS300. First-off whats the mileage on the car? Are you the first owner of the car, do you have service records on the car?
    Have your brakes been recently serviced?
    Are your tires new?
    Do they run true, i.e. do they have flat spots?
    Did you get the front control arm bushings checked? There is a possibility they have worn out considering its an 11 year old car.
    Are rims ok, you mentioned you only changed the front end rims....maybe the back rims are bent which is causing the vibration.
    Did you use roadforce for wheel balancing?
    Alignment could be out which could cause irregular wear patterns on tires and eventually cause them to vibrate.
    Many factors could lead up to the vibration you are talking about at the speed mentioned....please be more specific as to where exactly is the vibration felt from.
    Hope this helps
    Kind Regards

    Mr Shiftright, is there a BMW web site that shows illustrated pictures of replacing various components, on 7 series that is free for the use. Sometimes it helps to see a picture when they are explaining a repair or replacement, e.g. brakes

    Thanks in advance, if there is such a place.
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,644
    Gee I haven't seen such a place per se but I'm sure everything is out there if you have the patience to look. There are often sites that do this but most are subscription I believe. (like

    You know, if you are going to DIY, there is nothing like a paper workshop manual right there in front of you. Even if you aren't doing the repair, you can look things up and even take the manual to the dealer to show him what you are talking about.

    Hi, thanks for the advice. Hmm let me see if I can describe this best: I did have front brakes replaced, also, the front control arms were replaced, as well as bushings, as recently as 2 months. The car has 197,000 miles, I'm the second owner, tires and rims as just 1 year old, Bridgestone tires are on it. All 4 tires/wheel have been together since bought. runs great and drives great, except for the problem I described. Again, I appreciate you thoughts.

    Having two problems with our 1995 740IL BMW. We've had the car for about 21 months and ran into these problems last summer also. Wanted to know if anyone else had the same experience and if they had any luck correcting the situations.

    Problem 1: air conditioning stops working--only blows warm air when the car is idling--otherwise ac works fine.

    Problem 2: Digital Sound Processing Display goes out when temperature outside is 85 or above. When car cools off the Digital Sound Processing Display returns.

    Many thanks.
  • For the last few days the front passenger door on my 740i will not unlock with either central locking/key or from inside with the handle. Tried checking all fuses etc.with no joy, anyone have any idea how to solve the problem?
    Hope you can help as the wife is a getting a bit miffed having to climb in through the window all the time!!!

    I thinks its time to take it to a BMW dealership and get it checked out! See what they have to say and then go on from there...might be a ECU lock programming glitch or something
  • MrShift@EdmundsMrShift@Edmunds Posts: 43,644
    Can you put your ear to the door and hear anything working in that door? What I'm driving at is whether you have a malfunctioning lock motor that isn't even working or if the motor is working but the mechanical connection to the lock itself is busted.

    Hi...Newbi here:

    1. Can anyone tell me if there is any harm in burning 89-octane in a '95 7-series? My BMW mechanic says that's what he burns in his. He said "That's why they have knock sensors. The computer detects any knock due to octane and makes the appropriate adjustments to timing, etc. Can 89 really have a noticable effect on fuel injectors?

    2. Does anyone know of a place to purchase a repair manual for this car? I have seen them for 3- & 5-series...and for earlier 7-series (like Haynes, e.g.).

    3. I am the 2nd owner of this car. Bought it at 63,000 miles. It was pristine. Only problem was that I've had a shimmy since day one. The BMW shop that sold it too me went over the front end (and I have since had several other mechanics do so) and couldn't find anything they could attribute this to. He insisted that it was the tires. So I bought a new set of Dunlop A2 Sports...same problem. He then said "Oh, you HAVE to run Michelins on this car". So I next bought a set of MXV4s. Seemed fine for a short while, then back to shimmy (can feel it in floor board and very prominent in steering wheel). I've replace the rotors and brake pads. Any thoughts?

    Many Thanks

    I have been thinking af getting a bmw 7 after this last cycle change..I was wondering when the all new 7 would be introduced? The Lexus I have has the last four yrs is still a year away from the big change, and I also am tired of the same old same old, although it has been an easy car to own....I got my wife a new bmw 530xi station wagon and she loves it...I have been messing around with the i drive and find it complicated at first, but I think it will get easier with more familiarity...That has really been a big negative for even thinking of the bmw, so now I am thinking...Thanks Tony

    I have the same vibration problem and have the same tires as you do on my
    2001 740il. Having talked to BMW techs and gone to the website,
    I believe that Michelin Pilots are the best tires for the 7 series. When my MXV wear down, I will replace them with Pilots. Also, are your bushings leaking? That
    may be a factor in the shimmy. Air pressure. I run 33 psi in the front and 35 in
    the rears. Alignment. Costly and be sure that BMW techs use the weights in the
    care for the proper alignment. Good luck.
