Replying to: papsephus (Jul 24, 2008 4:22 am) 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. WARRANTY INFORMATION Covered under the terms of the BMW New Vehicle Limited Warranty. Please refer to the latest KSD for all applicable labor operations and allowances. If the appropriate labor operation is not contained in KSD, then a work time labor operation should be used. Defect Code 24 00 39 61 00

Replying to: Mr_Shiftright (Jul 24, 2008 7:00 am) 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!".

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

Replying to: Mr_Shiftright (Aug 19, 2008 6:47 am) 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

Replying to: cobra99 (Oct 11, 2005 4:56 pm) 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? |

I have a 1998 BMW 740i. The dealer indicates I need to replace my Catalytic converter and they want 5800.00. I have checked out a few forums and seems many people are using the Magnaflow (universal fit) model. There are also other choices and they can be confusing with converters being listed as left and right and even 'eastern'. Has anyone here had theirs replaced? Thanks in advance! Mike

Replying to: mevander1 (Sep 28, 2008 7:35 am) You might find this TSB interesting: GROUP 18 Exhaust Systems Bulletin Number 18 01 99 Woodcliff Lake, NJ September 1999 Product Engineering This Service Information bulletin supersedes S.I. 18 01 99 dated August 1999 which should be removed and discarded from your S.I. binder. SUBJECT: Unnecessary Catalytic Converter Replacements MODEL: E36 with M44 engine from 1/96 prod. Z3 with M44 engine from 10/96 prod. E36 with M52, 852 engines from 10/95 prod. E46 with M52 engine from 6/98 prod. E39 with M52 engine from 3/96 prod. Z3 with M52, 852 engines from 1/96 prod. E38, E39, E31 with M62 engine from 1/96 prod. E38, E31 with M73 engine from 1/95 prod. Situation: Analysis of returned catalytic converters has proven that some converters are not defective and are replaced unnecessarily. The reason for unnecessary converter replacements may be due to the misfire fault code(s) in conjunction with the statement "catalyst damaging" being stored in the Engine Control Module (ECM/DME). Example: Fault Codes 63 - 70: "Cylinder misfire detected - catalyst damaging" If a vehicle is found with the "Check Engine" lamp on and one or more misfire faults are stored in the engine control module, the fault code description "cylinder X misfire detected - catalyst damaging" will be displayed on the diagnosis fault survey of the DIS or MoDIC. The qualifier "catalyst damaging" is a reminder that this type of fault (cylinder misfire) may over time cause damage to the catalytic converter if it is not repaired. Troubleshooting cylinder faults should be carried out using the DIS or MoDIC i.e. check secondary ignition system, etc. A catalytic converter should not be replaced automatically when a - catalyst damaging" fault code is stored in the Engine Control Module. A catalytic converter replacement is only necessary if fault codes 40, 45 or 233 (E9 hex), 234 (EA hex) are stored in the Engine Control Module which are catalytic converter efficiency or conversion faults and/or if a customer complaint of an audible rattle noise coming from the converter is verified. |
