Secondary Air pump & valve

[cmartin248]

Check my post about 4 post up,, my codes p0491 and p0492 came in a few days after I replaced my water pump. While replacing the water pump, I apparently moved the small vacuum hose around and it cracked/split next to the recirc valve. Worth looking at due to your recent work...

also check something called the main sucking jet. when i was working on my water pump / radiator hoses i knocked this bad bay around and it caused some trouble. i just put it all back to together and everything was fine. don't remember the codes, maybe i posted about it, but it definitely ran like crap without the peddle floored.

part #1
RealOEM.com BMW E53 X5 4.4i Vacuum control - engine

the top popped off it (whats pictured to the right, that comes apart). i lined it up properly, snapped it back into place, used a little glue/sealant and used a zip tie to hold it together.

Sounds like I need to make a run to The Home Depot j/k

Thanks for the help, I'll try it. Hope it works.

Can prolonged driving in this condition cause any additional damage? Gonna try to bang this out today, or tommorow.

haha... i would say that you will most likely notice considerable drop in hp/fuel mileage/ and you may cause a bit of trouble if the engine is not burning all the fuel coming into the engine. (as far as build up on injectors and oxygen sensors)

i wouldn't be surprised if you have a bad oxygen sensor somewhere.
