#378 of 831 Shaky engine by my740il

Dec 01, 2005 (7:02 am)

I own a 1995 BMW 740il with 205k for the mileage, and its going through some problems right now. When the car is started it shakes really bad, and will not stay running for long without me giving it some gas. Sometimes the car starts up, runs fine and after being driven for a while and then shut back off again, it will not start back up for up to two hours sometimes. Any suggestions on what may be causing the engine shakes and the car from not starting back up right away?

#380 of 831 1990 735iL with trans problem by quigs

I have a 1990 735iL (204,000 miles) that needs a new transmission and has a power steering reservoir leak. It will only be driven for fun, about 10 miles a day. Is it worth putting $2,000 into it. Or should I expect to keep putting in $200 a month into it as I've been reading.

Well it's an old car that has, at least statisically, run just about as many miles as the engineers planned for. So its "natural" life is over, I mean statistically, and so you must expect maintenance costs to increase.
 
But with such minimal use, I don't see how you could consume $200 a month driving just 300 miles a month. You'd have to have really bad luck, or you'd be plagued by old problems you still haven't repaired.
 
So if the REST of the car is tip-top, then $2,000 isn't so much for such a nice ride...but if the car has other issues, this may not be a good idea because at 200K, anything can happen.

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

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.
 
thanks

#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.
