This might be a silly question, but I haven't seen it asked before. Since the EGR (Exhaust Gas Recirculation) pump is the reason our cars can sound a bit like diesels (or at least tappety) on cold starts for 20-30sec, I know it's normal - but it's annoying! The car sounds shit with the EGR running.

Can it be easily stopped (eg by a tune or disconnecting)?

And I know it has its purpose to reduce emissions - I don't want to harm the environment. But I don't actually drive anywhere in the time the EGR pump runs (I have to open my carport gate). I still run an emissions-legal 200cel Cat, and my GT isn't even driven every day - I have the work van for that. And keep in mind that 'cold starts' are not exactly that cold for my car, because it only gets down to 20-25deg here in winter.

Or am I missing another purpose/advantage of the EGR?

Do yo mean the secondary air pump? This guy pump clean air into the exhaust to low emissions on start up.

If so, yes it can be removed completely/ tuned out - a lot of people have issues where these fail and throw a cell and have to either be tuned out/off, removed or replaced

Yes, I think so. This one in the left side of the engine bay (no pics but a description and a video with a brief mention at 1m 35s) http://forum.liberty.asn.au/viewtopic.php?f=18&t=7244

Excellent . Thank you. I will contact Matt (KiDo) at some point and getting it tuned out then.
