I SHUT OFF MY SRT-6 AND when walking away i could hear a loud spinning noise from under hood so i opened the hood and the AUXILIARY AIR PUMP part # 0-580-000-021 816 was spinning with the key in off and i could smell like a wire burning so i pulled the 2 wire prong from the unit and lit it cool plunged it back in to see what was happening and nothing it seems OK i start the car drive to work and it seems OK ......i really don't know what this unit does except its for smog from what i read so far....can my car run without this unit or will it cause Moore problems....has anyone Else had this problem?? it seem fine but maybe i should replace it ....if so wheres a good place to buy it from ??....( THANK YOU FOR ANY INPUT!!)

 

The pump is probably still OK, you probably have burnt contacts on the air pump relay in the RCM causing it to stay on at times.
You can leave it disconnected without causing any damage, it is just to heat up the O2 sensors faster at initial start.

 

THANK YOU for you input i knew it was for smog but i did not even know what part it played,( like if it had to run all the time) but you did inforum me so again thank you

 

If you disable the air pump then eventually you will get a check engine light with a code for secondary air issues. I would repair the relay, and leave the pump operable. These pumps are most active in winter and sometimes don't even activate in warm summer weather.

 

if you do get a check engine code it won't pass smog inspection, (at least it won't in CA) you may need to clear it before you get your smog done and also make sure you schedule your smog appointment in the afternoon after you've driven it for a few miles. I replaced one on my BMW and it had blown the relay too, it also blew a fuse, not just any fuse, but one not listed in the manual. I found it, after a lot of searching on the internet, under the front passenger seat, under the carpet, and I believe it was a 60 amp fuse, an expensive one, like everything else on that car.

I found the air pump off of ebay, new for about half the price BMW was asking.

thank you all for the input so far no code.......im looking now for a new pump..is this pump like everything else on the car, like look out for who made the new part?? and is a rebuilt one OK to use? whats a far price ?

 

Sent ya a PM reference replacing the relay.

 

If the problem is the relay situated in the RCM why would you waste the money on a pump? You get advice and then ignore it.

 

sorry.... if you had meant me you can tell i have had a stroke on line you cant i understand ....... my speech is not good and sometimes i dint understand things ..... the air pump got so hot i could not touch it and i could smell something like wires burring so my thought process was something bunt in side of the air pump so thats way i was asking if it also needs replaceing ...... i was not trying to ignore anything just wanted to repair all that needs to be....

 

The problem basically is the relay, I would fix that first and if the pump still works you are good to go, if not then get the pump.
Why waste money on something that may be fine.

 

" THANK YOU"!! for your help ..........

 

OK thats what ill do ...im sending my PCM for repair....thank you

 

RCM, not PCM. Don't send the wrong module to DJ ( tighed1 )
The RCM is the one closest to the engine with all the fuses on top.

 

yea thank you thats just a typing air.... DJ sent me the info on removing the RCM and sending it to him for a few updates and the repair.....

 

i now have use of my wifes car for a few days so im pulling out my RCM and sending it to be repaired .......sunday morning on the way to church my CHECK ENGINE light came on im hoping it is because of my needed repair so after i get my RCM back how do i clear the CHECK ENGINE LIGHT??? im thinking i have to go to a shop to have it done or when the repair is done no moore problem and light goes off???

 

For engine management Check Engine Lights you should be able to go to Kragens and get it scanned and reset for free. It may reset itself after a few drives.........

 

Thank you for your help...

THANK YOU VERY MUNCH FOR THAT LEAD IT WILL SAVE ME A LOT IF NEEDED ......im going to wait till i get my RCM back and see if i do need a new air pump ..........

 

i pulled my RCM out sent it off to D.J. for repair and yes my points needed to be replaced so D.J. did a great job going out of his way to repair and get it back to me as the fire was only 7 miles from my front door so we where ready to go but as it turned out the fire went the other way and is now 40% contained anyway i received the RCM put it back in place and hooked battery back up and it worked very well and the engine light went out so today i drove about 80 mils or so and bang the engine light came back on so im thinking i DO NEED to replace my air pump???....
