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.

Replying to: nickyc1974 (Jan 13, 2009 9:45 am) 3 Series Bugaboos However, with those low miles I wouldn't think too many items on the list would apply, so you may be okay. What I'd do if i were you is download this list of areas of concern and show them to the shop that checks out the car for you, and let them inspect these items. Some are minor, like valve cover leaks, and some don't apply to the M3, like the oil separator. Others might apply to low mileage, like the BMW power steering hoses, which tend to leak and which cost an outrageous amount of money for some reason. Anyway, I'm not sure Consumer Reports has much of a handle on BMWs. |

I have 49000 miles on my M-coupe. I have worn out my rear tires twice (byproduct of my right foot) but my front tires are just now coming to the wear bars. I want to get an alignment, but fear not getting the M numbers right. Does anyone know the correct specs for an M-Coupe? Also, I've called the 2 tire shops that I typically send my customers to, and they both told me to see the dealer because of special tools etc. needed to perform the alignment correctly. Is that right?!?!
