Noisey pump thing??

[eliterob]

hi all i have a noisey pump thing mounted below my nsf headlamp behind the bumper.
my question is this..
1 what is it?
2 what does it do?
3 what would happen if i just unplugged it?
if it helps it only rins for the first 30 seconds or so when i start the car.

thanks in advance rob

Its the seconady air injection, fitted to assist in a clean qquick cats warm up cycle to reduce emmissions etc...

No harm in simply unplugging it, lots of them have been disconnected....

just what i wanted to hear
thanks bud

Or if you want a non noisy one...I can send you one cheap

...but if it was me i would leave it connected - it should only be a noise occassionally when cats are cold and not impact anything else.

the only reason I disconnected mine was to confirm that was what was squealing for 30 seconds after starting from cold (and not something more critical).  Otherwise I would leave it connected.

It may not be that important but it is there for a reason, so why not just get urself a cheap replacement and have a non noisy one

It is there to get the cats up to temperature faster but Vx themselves dropped it for the 2.6 V6.

I preferred to replace mine, but rather than unplug it you could remove it, it's a big lump and you'd be lugging around dead weight.

yup - if mot`d properly it will fail - or you will need to put them back in for mot and remove again.
