    So I've encountered my first SAP on my grandfathers E46 318i. Basically the motor is not working (when cold it basically has an exhaust leak), I measured power at the plug and getting nothing. Checked 50a fuse in panel, checked the fuses in the engine bay, replaced the relay behind the...
  2. E60 / E61 (2004 - 2010)
    Let me start with by saying, I've had this code pending every since I had the car, never went away after clearing the code but only if it was hot outside and car was up in temp. Recently, I've updated some modules on the car usng Winkfp and now the code isn't there anymore and engine light is...

    Hi all, Please help, I've got a 318ci n46 4 cylinder and can hear a roaring sound from the engine on a cold start that lasts for about 2 seconds. I'm pretty sure it's the secondary air pump, but after looking for it i can't find it anywhere. I've seen a few pics where it shows the sap should be...
  4. E36 (1991 - 1999)
    Alright, so I keep getting this code and I can't figure out what to do. I am trying to get this car smog ready for CA and at this point I'm trying to avoid the SAP dummy connector. Car: 1999 BMW M3 - Automatic (Stock S52) Problem: Code P1453 -Secondary Air Injection Pump Relay Control Circuit...

    Hi all - I purchased a 2003 540i about 4 months ago and have dealt with SAP issues from the beginning. The pump was really loud, sounded like a vacuum cleaner with a sock stuck in it. I tried all the diy's out there including cleaning and replacing the valve but nothing would alleviate the...

    I've been all over the internet and forums. I know they're out there. Does anyone have a link to somwhere that sells headers for a 1998 528i automatic transmission that are OBD-II compatible (ie they have a spot for those small metal tubes to go, and the check valve to attach to as part of the...

    Good Morning - hope all are having a great Labor Day Weekend. I spent Sunday afternoon troubleshooting an P0491 error code on a 2002 540i with 125,000 miles. So far I have: 1) Removed Secondary Air Pump - connected to battery - validated it works - cleaned filter - reinstalled. 2) Inspected...

    Hi all, Does anyone out here have any recommended product(s) to use to remove a light sap stain from the cloth roof of my convertible. Obviously nothing harsh ; stain is less than 2 weeks old (was not there the last time this OCD BMW owner wahsed his car ... lol). Also any ideas/suggestions...

    This quizzically precise suggest by Steve530 today got me wondering how the secondary air system (SAS) actually works: - E39 (1997 - 2003) > 2001 530i question... Doing a search for "SAS" in the bestlinks, I skimmed these threads to see if there was a good description of how the entire...
  10. E39 (1997 - 2003)
    I recently got a CEL and the Peake code 0F50, 0F51, 0F5D seem to suggest it's related to SAP, I tried to clear it but it will come back within a few days. I read a lot DIY's about SAP but most are for I-6 engine where the air valve is easy to access, I had a hard time locate the air valve which...
