740i passenger window rubber guide removal by scholder
Jun 07, 2008 (9:30 am)
Reply
trying to replace a window regulator and while dismantling window having a problem in removing the rubber guide along the side of the window. There seems to be no starting point or joint where to work from and don't know if a special tool/trick is needed to get it started. The step before called for removing the outside metal covering strip which I did. Next step says remove screws and take off plate. Could someone help explain better?

'03 745 Transmission bump when stopping by papsephus
Jul 24, 2008 (5:22 am)
Reply
When I'm driving my car and am stopping at a red light or stop sign I get a bump that lurches the car forward right before I come to a stop. It has almost caused me to hit the car in front of me when I'm parking at the grocery store.
 
The car is still under warranty, and they have done some reprogramming, but it has not worked. Has anyone else experienced this? I think I might need some transmission parts replaced, but I think they are holding off because I have 83,000 miles and the warranty is up in January '09.

Sounds like a delayed and harsh downshift into 1st gear. Maybe electronic problem? They should be at least reading the trouble codes.
 
Here's a TSB on the subject:
 
SI B 24 17 07
Automatic Transmission
 
July 2007
Technical Service
 
SUBJECT
Harsh 3-2 and/or 2-1 Downshifts
 
MODEL
E65 and E66 (7 Series) 745i and 745Li with N62 and GA6HP26Z transmission
 
Vehicles from SOP up to 03/2005
 
SITUATION
IMPORTANT :Depending on the production date of the vehicle; there are different situations, and corrective measures, that must be carefully followed. Running production changes in vehicle hardware and software divide these situations into three distinct production periods.
 
A. For vehicles produced from SOP up to and including 02/2003:
 
^ Harsh 3-2 and / or 2-1 downshift when slowing to a stop
 
^ Harsh downshift when accelerating at highway speeds
 
^ "Clunk" noise during a 2-1 downshift while driving slowly to a rolling stop, or during load reversal as described in SI B24 14 07 and SI B26 01 06.
 
B. For vehicles produced from 03/2003 up to and including 08/2003
 
^ "Clunk" noise during 2-1 downshift while driving slowly to a rolling stop, or during load reversal as described in SI B24 14 07 and SI B26 01 06.
 
C. For vehicles produced from 09/2003 up to and including 02/2005
 
^ Harsh 3-2 downshift when slowing to a stop
 
^ "Clunk" noise during a 2-1 downshift while driving slowly to a rolling stop, or during load reversal as described in SI B24 14 07 and SI B26 01 06.
 
CAUSES
EGS software calibration
 
Driveshaft guibo coupling deterioration for "clunk" noise complaints
CORRECTION
For Situation A: Harsh downshift complaints
 
1. Verify that the transmission fluid level is correct.
 
2. Perform a "Short test" and correct all Drivetrain related faults first.
 
3. Submit a Puma case titled "Coasting Jolt" to obtain the access code needed to complete the retrofit reprogramming of the EGS module.
 
4. Start a Progman session using only V26.1.1 or higher and select "Coasting Jolt" from the retrofit options menu. The measures plan should indicate a higher programmed number and an EGS calibration change.
 
5. Clear the EGS adaptations after programming is completed.
For "clunk" noise complaints, vehicles produced 10/2002 up to and including 02/2003, inspect the driveshaft guibo coupling for deterioration or separation as described in SI B24 14 07.
 
For Situation B: "Clunk" noise complaints
1. Verify the complaint
 
On vehicles produced from 03/2003 up to and including 08/2003 the only repair is to inspect the driveshaft guibo coupling for deterioration or separation as described in SI B24 14 07.
Note :There are not any further EGS software changes for vehicles in this production period. For Situation
 
For Situation C: Harsh 3-2 downshift complaints
1. Verify that the transmission fluid level is correct.
 
2. Perform a "Short test" and correct all Drivetrain related faults first.
 
3. Submit a Puma case titled "Urban Program" to obtain the access code needed to complete the retrofit reprogramming of the EGS module.
 
4. Start a Progman session using only V26.1.1 or higher and select "Urban Program" from the retrofit options menu. The measures plan should indicate a higher programmed number and an EGS calibration change.
 
5. Clear the EGS adaptations after programming is completed.
 
For "clunk" noise complaints, vehicles produced 09/2003 up to and including 02/2005, inspect the driveshaft guibo coupling for deterioration or separation as described in SI B24 14 07.

Thanks Mr. Shiftright,
 
I am taking it back the dealer next week. They have always done a great job on my vehicle and I have always been pleased with their excellent service. But the vehicle has been in twice on this issue. Hopefully they can resolve it this time.
 
I have had this vehicle for five years and I have to say that I love the engine, the handling, and the comfort. But this one thing spoils it all, especially when you have a new passenger and they say, "what was that!".

Brake job on 1998 740i, help by mevander1

Hello all,
I have had my 1998 740i for 6.5 years. At 75,00 miles it needs another brake job, both front and rear, however I don't want to pay the dealer the high $$'s, approx 1100.00 for the job. Anyone have a good experience having it done by someone else than the dealer and what price?
 
Many thanks!
 
Mike

That's actually not too bad price for that job, in my experience. I've seen it as high as $1,800 for a 7 series. I presume this is all 4 rotors, etc?
 
Sure, shop around but stay away from chain stores. You don't want Chinese pie plate rotors trying to stop a locomotive. Quality German parts, please.

I have a 2000 740il and I do my own brakes -they are quite easy - for added help they have a pictorial view i believe in the bimmerforum sorry I dont have the link
5 key items
metric hex driver is needed (easy to buy)
Use only Greman rotors (chinese rotors warp trust me
need a flat bar and big c clamp to pull back the pucks
replace the electronic sensor
 
total cost with german rotors should be in the $800 - I enjoy it for 1100 and Germany Rotors you may want them to do it

Thanks for the replies! Mr S. How handy do you have to be to do it yourself? I am not that mechanically inclined, except when it comes to PC's. (everyone comes to me for help there and can tear one down and back,.. not my day job:)

I always encourage people doing DIY to have a good repair manual, read over the procedure as it is listed, then check in here before you start if there's something in the procedures you don't understand. As long as you don't open the hydraulic system, I think you'll get by with genuine common sense, a few good tools and a repair manual.
 
The public library may have this.
 
I'm sure would give you some free advice!

Hi
 
I have the same car, and same problem, only SOMETIMES the radio works, sometimes not, (mostly not lately).
 
I bought a replacement (used) radio and swapped it out and NOTHING.
 
Did you ever find out the cause?
