#383 of 831 NAVIGATION SCREEN WON'T APPEAR by bmwthad

Dec 02, 2005 (9:44 pm)

I WENT OUT OF TOWN FOR 4 DAYS & WHEN I CAME BACK MY 2001
BMW 740IL WOULD NOT START. I GAVE IT A HOT SHOT TO START IT. IT STARTED RIGHT UP BUT I NOTICE THAT THE NAVIGATIONAL DISPLAY SCREEN, MY TRUNK RELEAST & ALARM WOULD NOT
COMING ON. A FEW DAYS LATER THE ALARM & THE TRUNK RELEAST
MAGICALLY STARTED WORKING. BUT THE SCREEN IS STILL NOT DISPLAYING. THE DEALER SAYS THAT THE SCREEN IS GETTING SOME POWER BUT THEY ARE NOT SURE WHY IT IS NOT WORKING. CAN SOMEONE PLEASE HELP ME? BECAUSE THE DEALER COULD EASILY SPEND A FORTUNE TRYING TO FIND THE PROBLEM.

#384 of 831 Check Engine light issues - 740i by vchiu

Dec 03, 2005 (12:36 am)

Dear all
 
I am the owner of a 2000 740i I bought second hand in february 2005. I drove it about 6K miles and reached about 110K miles overall.
 
My main problem is that the "Check Engine" light is always on.
My early mistake is that I did believe the salesman who told me that this was an unimportant glitch and that the Engine works well.
Indeed, it went through pollution test with success, whereas the engines revs smoothly and silently. I am just a bit disappointed by the car overall performance, as I would have expected more torque and brisker speed pickup.
 
The BMW repair agent is unable to give me any explanation for this light. It seems his computer does not give much over standard figures. 2 Lambda sensors have been exchanged and "check engine"light reset, but it light up again after 30-50 miles.
I had the card serviced immediately after buying it (in the BMW network) and no issue was diagnosed.
Twice, the light went out itself for a few minutes, when I was going at slow speed, but it lit up again and solid.
 
The on-dash computer gives me too optimistic figures by a consistent 6%. My average fuel consumption must be around 18 MPG ( 14l/100km), 20% city,50% highway, 30% smaller roads.
 
Does anyone has a clue?
 
Thank you for your inputs

Try posting with CAPS LOCK off. Most people find this type of posting very hard to read and skip over it.

#386 of 831 navigational screen won't appear by bmwthad

Dec 03, 2005 (5:16 pm)

I went out town for 4 days & when I came back my 2001
bmw 740il car battery was died. I gave it a hot shot & it started up but I lost the display on my navigational screen, the truck release and the alarm would not work.
   
Magically a few days later the alarm & trunk release started working but the navigation screen still would not come on. the dealer briefly look at it & seems to
think that the screen is not bad because it has power & sight illumination. Can someone please help me. the
dealer could cost me a fortune trying to find the problem.

I have an identical car 2000 740IL and know that the scroll feature to select is clumbsy and difficult. I am sure you have probably tried to click the knob in to see if that free's up the problem. My computer did hesitate often and pause sometimes for long periods of time when entering selections and it was frustrating, but not as frustrating as when it recently just died and the screen faded to black and has not come back. In addition, Navigation System FAILURE - HELP!!I have an identical car 2000 740IL and know that the scroll feature to select is clumbsy and difficult. I am sure you have probably tried to click the knob in to see if that free's up the problem. My computer did hesitate often and pause sometimes for long periods of time when entering selections and it was frustrating, but not as frustrating as when it recently just died and the screen faded to black and has not come back. In addition, the radio will play for about 2 minutes, and then it shuts off automatically. I have to double click the on\off knob and the radio comes back on, but then 2 min. or so it shuts off again....and so on.
 
I know the radio must be caused by the navigation system problem but my dealer has no intention of trying to solve the problem, they want to sell me a new car at best or at worst, a new navigation system for thousands. Somehow I think there must be a better and more reasonable solution.
 
I am afraid your small problem could be the beginning of a bigger problem like mine.
 
I bought the car new, paid well over $70k when all said and done and after 5 years, this system should not be failing and if so, there should be a reasonable fix available.
 
Sorry I couldn't help you, but I am having similar problems. Others say when you disconnect the battery or get a jump, that is what causes the problem, but I did not have any electrical issues that could have caused this.
 
I recently brought it to the dealer to fix a low coolant level situation, brakes (front and back) a suspension problem, wipers, brake light and oil service (over $4k) and he tells me another $2,600 or more if I want the Nav system replaced.
 
HELP

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.

#390 of 831 E38 730i brake light sticking on by tigs

Dec 23, 2005 (8:03 am)

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?
Thanks
