HI Just need to know what is the right tool to use for the drain plug. The last time/1st time I change the oil, i used a hex key to remove and tighten the drain plug. Since there was no way I can use the torque wrench, I hand tighen the drain plug (using new washer) with the hex key as tight as I can without stripping it. After a couple of months, I saw oil leak from the plug. I realized that the drain plug looks like it can be torqued with a torx set even though the hex key works. Now is time for another oil change, I used the torx to remove it but it started to slip. To prevent any damamge with a stuck drain plug that will require to be tapped out, I decided to leave it alone until I figure out the right tool. If it does use a torx, what size am I suupose to use? It was either T40 or T45 that had the best fit but still slips. Or am I suppose to get a hex key to remove and use a hex key end that can go on my torque wrench to tighten down properly for seal. Thanks! |

does anyone have DIY direction and diagram/photo on the air pump/ valve and where it is located? Bentley manual shows nothing that I can find on that and i can't seem to find anything detail on other forum, aside from the fact that peole claim is a easy easy diy. The dealer quoted a price of $1000 for parts and labor any help will be appreciated

Replying to: gmonkies (Jan 08, 2009 11:18 am) GROUP 12 Engine Electrical Systems Bulletin Number 12 04 00 Woodcliff Lake, NJ July 2000 Service Engineering SUBJECT: Secondary Air System Faults MODEL: All models with M52 and S52 engine All models with M44 engine produced as of 1/97 All models with M62 engine produced as of 9/98 All models with M73 engine SITUATION: Customer complains that the "Check Engine" lamp is illuminated and the following fault is set in the Engine Control Module (ECM/DME): M52, S52 Engine: Fault code 245 (F5 hex) - Secondary air injection, bank 1 Fault Code 246 (F6 hex) - Secondary air injection, bank 2 M62 Engine Fault code 80 - Secondary air injection, bank 1 Fault Code 81 - Secondary air injection, bank 2 M44 & M73 Engine Fault Code 80 - Secondary air injection system CAUSE: Failure within the secondary air injection system. PROCEDURE: The following diagnostic tips / steps should be followed if the above customer complaint is received: 1. For E36 vehicles equipped with M52 engine prod. 10/95 - 2/96 also refer to S.I. 12 04 96 regarding Recall Campaign No. 96E-A01. 2. Refer to the OBD II training manual for illustrations and explanation of system operation. 3. Perform test modules/component activation of secondary air system located in the "Service Functions" section using DIS/MoDiC. 4. Check operation of secondary air pump using instructions provided in DIS/MoDiC. 5. If pump is not operating correctly check air pump relay. For vehicles with M52 engine a modified relay was introduced into production P/N 12 63 1 742 690. 6. If the relay is operating correctly and the electrical connections/wiring to the pump are OK, check the condition of the pump. 7. If the air pump is seized it must be replaced. Important note :If the pump is seized as a result of moisture (water in pump), an improperly operating non-return valve is the cause. The non-return valve may stick open and allow exhaust gases to condense within the air pump housing leading to a failure of the pump. Non-return valve sealing / leakage check: The non-return valve must be checked as follows any time a seized secondary air pump has been replaced due to moisture. Disconnect the air pump feed line/hose at the non-return valve (line from the secondary air pump to the non-return valve). Visually inspect the non-return valve fitting internally for carbon type contamination. (Twisting the corner of a clean shop rag into the valve fitting as shown will assist with this check.) If no carbon type deposits are found on the rag, this indicates that the non-return valve is sealing correctly and does not need to be replaced. If carbon type deposits are found on the rag, the non-return valve is not sealing correctly and must be replaced. Note :A non-return valve which is not sealing correctly will cause damage to the secondary air pump as described above. 8. Check also for cracked vacuum lines going to the non-return valve. -- For vehicles with M44 engine the vacuum line P/N 11 73 7 501 180 going to the non-return valve has been improved since 11/98. -- For E46 323i/iA and 328i/iA vehicles produced 4/98 - 7/98 see S.I. number 12 04 98 regarding the vacuum hose to the secondary air non-return valve service action.

Replying to: jd1971 (Jan 09, 2009 9:37 am) I really don't know if these loopholes have been corrected or not. I'm just so used to being on alert with titles from New Hampshire and Alabama that I remain on high alert when I come across one. Didn't mean to alarm you! Best thing for you might be something like Auto Check |

I am thinking about buying a 2005 BMW M3 fully loaded with navigation with 48,100 miles. I was wondering if there are any known reported repair problems with this vehicle? The 2008 Consumer Reports Buying Guide saids it is a used vevicle that should be avoided. It reports transmission, electrical, power and suspension problems, but most of my internet research for the most part does not state anything like this.
