Hi,

I got a 2004 BMW745Li, it has run over 130000kms. Can somebody tell me, aprox how many kilometers more it will run reliabily. I heard cars become trash after 200000, is that true?

Then, how do you personalise the settings of the cars? How to program the Car memory- like to automatically lock the doors, audible alerts etc. Anyone knows where to get the list of programmable options for my car? Can this be done by ourselves? If taken to the dealer, how much will they charge for doing the programming?

Now the problems that I face with my vehicle:
1. The airbags show an error, even though the problem was fixed.
2.The driver seat seat cooling shutsdown after a few seconds. Sometimes it functions for 3 min- but still it shutsdown automatically.
3. The cd drive does not work- the shutter in front opens and makes some wierd noises but nothing else happens.
4. The trunk does not open fully with the remote and it has trouble opening on its own and occassionally needs manual human help.
5.The doors get stuck, and requires extra effort to push open at times.
6.And now the MAIN problem- The air conditioning! Theres wierd and nauseating smells coming from the air conditioning. It also smells damp and very dusty, like an old unused attic. If the MAX setting is put on, the problem reduces to the front passengers, but the back passengers still face the problem.
7.The front light covers have faded too, the dealers tell me its because of the excessive heat from the Xenon lights. I tried cleaning from the outside, but it seems the problem is in the inside of the cover.

I would love to hear any opinions to my problems. I also hope that an expert can tell me how to solve my problems and how much it would cost me to do it.

    it seems to me like you need a ton of repairs done on your car. It also seems to me like you don't maintain your car that funny smell from the AC that might be the cabin air filter, the doors i would buy some WD40 and grease the joints same thing with the trunk also do the hood, about personalizing your car i would try to find an owners manual the cd you may need to repair the air bag your gonna have to get diagnose. solve all these problems before 200k you may have to change the water pump alternator, battery and may other components that have a life span of about 150k

    I can answer a couple from personal experience.
    I wasn't able to set the door locks myself (I was told) because of the 745Li brain. If I took it in just to have something like that done, my dealership would charge $50. Next time I was due for service, I had them set it and I didn't have to pay.
    Also, my car's trunk did the same thing. The paperwork said: Cause - Rear lid Gas pressurized spring no effect. The repair - Replaced both gas pressure props.
